    Pro-ject Phono Box S, set up?

    Sorry - I swear I had more smilies in that post than that (just reread it and my post might come off a tad rude :-( ) I blame Tapatalk - no decent icon integration imho Btw the reason I’m using Tapatalk is I only have my iPad/iPhone on me ‘cos I’m here: Sent from my iPhone using Tapatalk

    Pro-ject Phono Box S, set up?

    Yes I know mine is different - because I own a DS+. I also know it’s all set via buttons rather than dip switches - because I own a DS+ . That’s why I specifically mentioned “your manual” before posting a picture of the ACTUAL PhonoBox S manual that the OP has (you might want to reread it if you missed it)...... ......those dip switch positions are those from the OPs user manual and are the values recommended for his given cart Sent from my iPhone using Tapatalk

    Pro-ject Phono Box S, set up?

    According to my Phono Box DS+ manual, Gain of 40db is "standard" for MM, or 43dB is "standard" for High Output MC, 60db or 63dB is used for Low Output MC carts. Here is the relevant page from your manual: Your capacitance is recommended for 100-200pF so I would set that at 100pF (within range) and change to 200pF to experiment. as mentioned, your load impedance should be set at 47000 Ohms - which is all those resistance switches set to off So for example (U=up/on, D=dpwn/off): 40db Gain + 47kOhm Impedance + 100pF Capacitance would give you: UDU DDD DD 123 456 78 OR 40db Gain + 47kOhm Impedance + 200pF Capacitance would give you: UDU DDD UD 123 456 78 EDIT: Bloody 'ell - 10 replies in the time it took me to type that up

    Skyline diffuser ?

    From the post title I thought you meant this for a minute: . . . . . . . . . I'll get me coat
  5. I know I'm arriving a bit late to the party but based upon my experience (I own some ribbon super tweeters myself) super tweeters are not only "super", they're also "normal". They ALL extend into the audible range and it is THIS that alters the sound: Townshend Maximum - their own website clearly shows extension down to 2kHZ - yes it's down 20dB, but the next plateau is from 10kHZ - it's therefore still adding to the audible band Tannoy ST - manual sets many XOs at 14kHZ - again within the audible range. My point is that the reason they change the sound is they are within audible range and are therefore simply.....tweeters. You could get some PYLE tweeters and piggy back them onto your speakers and have a similar effect. The "super" part of these tweeters won't have any effect on the sound....for a human anyway. One way to check is for a manufacturer to make a "Super Tweeter" that ONLY works above 20kHZ and then try to sell us the same story of it altering the sound lower down and then you can also hear for yourself if they truly work as advertised ----- I wonder why none of them do that ...hmmmmmm Plus, I have Tannoy DC - i.e. a point source......which would no longer be a point source if adding a tweeter on top (for the audible range) and would be pointless adding a superthingy on top (for the inaudible range) - all imho of course (bought mine for use with my Quad 12Ls as they were a "laid back" speaker and yes, they extend into the audible range too - been packed away unused since I got my Precision 6.1s)

    Pro-Ject Phono Box DS+

    Well I got the 2.5-2.1mm convertor jacks and can provide some thoughts on the improvements: A-B comparisons between them, with LPSs on = slightly less grainy/harsh treble, same deep bass but better controlled, slightly more forward soundstage. ^^^ Of course this is all VERY subtle so it's not exactly night & day but it's enough of an improvement to warrant the (£69 each) outlay. I have also heard a friends circa £250 LPS upgrade on his similar phono stage (bought in the UK) and don't think it offers anything better than what these ones do so I'm quite happy with the results.... ....happy enough that I've just bought another one from the sister company (Breeze Audio) for the DAC/DSP Oh, and I did those things as advised: 1) Earth cable to a plug so get earthing lead - connected to Phono Stage ----- No change that I could discern 2) Put the gain down to 60dB from 65dB and use the amp to provide the gain ---- MUCH improved with much less audible hiss now. There is still a very tiny bit present if you listen hard for it (which wasn't there with my previous 2 box system) but it is almost negligible and as it has improved with time thus far, I'm hoping it continues to do so

    Pro-Ject Phono Box DS+

    Will try that on a spare plug socket (got plenty of wire floating around in the garage so should be able to knock one up easily enough) ..........but.....whilst fiddling around today I moved some things around the back and now the hum has gone (from the tuner input - i'll still do that plug Earth trick though).... ....talking of which, that upgrade I was talking about earlier arrived today: Linear Power Supplies . Unfortunately, stupid me didn't order the correct DC Jack sizes (I swear I measured them at 2.5mm but they're apparently 2.1mm).....so until the DC Jack adapters arrive, I can't try 'em out . PS. They look 'on' but the units are being powered by their SMPSs - this was just to get an idea of what it'll all look like powered up. The LPSs do look a bit oversized where they are so I might move them around later. EDIT: To give you an idea of how flimsy the original Pro-Ject SMPSs are, here are the Speed Box S and Phono Box DS+ ones compared to a penny: ...and here compared to the much heftier Graham Slee one: So I was always looking to upgrade to LPSs

    Pro-Ject Phono Box DS+

    Aah, thanks, I'll try reducing the gain to 60dB (today it sounds a bit better though). I have noticed LOTS of interference and hum on the Phono input when I turn the tuner on (which didn't happen before) so I think i'll try something else first as I reckon I can isolate whatever's causing it..... I think you can get Pro-Ject ones like the Power Box (about 4 different models I think) or 3rd party ones. I must admit, it's one of the disappointments with this, the wall wart is probably the smallest/flimsiest pile of carp I've ever seen bundled with a device.....even the Speed Box S has a bigger more substantial PSU. I was considering doing something similar. Before I had an earth wire connecting chassis of PL-Z to chassis of Communicator and then from Communicator to TT. Now there is just TT to Phono Box -> should I add one from Phono Box to Amp or is that too much? When you say "mains earth plug" you don't mean connecting a wire between it and the mains earth directly do you?

    Pro-Ject Phono Box DS+

    So I have been listening to my vinyl with this (the 2 boxes in the middle): Initially had a Grado GF3 MI high output cart with a Graham Slee Phono Stage (rrp £150)...... but then I upgraded to an MC (low output Ortofon MC15 Super mkII) and needed either a SUT or other pre-preamp to bring it up to the level to allow me to carry on using my Communicator. I bought a Pickering Perfection PL-Z (rrp £140ish?) to fulfill this role and everything worked well. Positives are an inky black silence with little bg noise - which I attribute to the PL-Z being battery powered and the Communicator being quite well behaved in this regard. However, I have noticed a negative in that although it sounded good, it was very bass-light. Switching between CD and Vinyl for the same tracks and bass would just disappear. Reading around the forums and quite a few folk have mentioned this as a "feature" of GS amps, but I think my problem lay with the fact that that PL-Z was designed for Pickering MC carts so I suspect the setup wasn't impedance matched to my cart maybe? (e.g. the Ortofon requires >20Ohm but maybe the PL-Z combined with the GS was less than this - I don't know as it's hard to find quantifiable evidence online about what they're "set up" as). So anyway, I thought I'd take a punt and upgrade to a different Phono Stage: Enter my new Phono Box DS+ (rrp £275).....a dual mono design with much more configurability than I currently have. I'm amazed how few reviews there are on the web (you can pretty much find reviews of most of Pro-Jects multitude of phono amps but I can't find one for this anywhere). Stereo Separation/Soundstage: WOW, it's an order of magnitude better than the previous 2 box set up - soundstage wider, deeper and taller with more spread out sound/better stereo separation. For instance, whereas before a vocal and a guitar string for a track might happen to be roughly centre line in the same spot, now they are in distinctly different spaces not just L-R but also Front-Back. Treble/Midrange: Much better texture and definition - Dire Straits Brothers in Arms sounds brilliant with strings being plucked in the air in front of you. Bass: Yaaaay - I have bass back. The configurability has let me experiment and with lower impedance the sound becomes bass light, higher impedance a bit bloated. 100Ohms is perfect and within the range Ortofon recommend for the cart. It's not too much to need the Subsonic Filter on but I can feel the floor shake with some records now (talking of which, I don't need the filter on as my sub DSPeaker has one already) BG Noise: Here is the only negative in that it initially had more bg hiss when I first switched it on than my previous set up, but over the day, bizarrely, it has definitely improved and is almost no noisier than the 2 box setup now. To be fair this has confused me as I'm not sure what to make of stories of "run in" (unless you're talking about speakers).....but there is a definite improvement here over time. ^^^ It just arrived today so maybe it will improve with use and as I fiddle but those are my initial thoughts (given that I found it so hard to get reviews before I took the plunge). I'm due a different upgrade in the next few days which will give the other reason I switched to the DS+ (will post a separate thread) but overall I'm very impressed and would recommend it to anyone else looking for a circa £250 all dancing phono stage (I got it for £247 online).

    Tannoy Prestige Stirling GR or ATC SCM40 ?

    Well the toe in is such that they cross about 1.5ft in front of my ear position when sitting (I'm trying to approximate what Tannoy recommend at the moment as I can't measure it**). My ears are about 100cm from the ground on the seat and the plinths raise the tweeters to 96cm - which is much more on-axis than the 71-72cm height they'd be when on the floor. I'm still fiddling so will keep trying different angles and the felt pads (used for furniture normally on hardwood floors) on the base of the plinths makes sliding them around relatively painless despite their 30kg weight ** Actually I think I think I can try to calculate more accuracy -they cross at a point roughly 306cm away from the tweeter-tweeter line (tweeter @ back wall -> X point = Opposite), the tweeters are 243cm apart (tweeter-tweeer = 121.5 Adjacent) ------- using sohcahtoa, angle to back wall = 68.344deg , meaning toe-in angle (angle from side wall) = about 21.7deg where they cross. If I point the speakers directly at my ears, using the same method they'll be toed in about 18deg............so if Tannoy suggest 15deg "further in" than on-axis, that means a toe in angle of 33deg, so I could try moving them in a little bit more....

    I quite like the look on the ....ahem...custom plinths ....but you're with my wife on that one, she prefers them on the floor too. The plinths don't really change the character of the sound at all, they merely bring the soundstage up so it now sounds like the singer is standing in front of me rather than all of them being double amputees. Plus they weren't very expensive. My grills are off as I find they don't just do the cut in treble as mentioned, but also have a diffractive effect making the soundstage slightly recessed/compressed (which is fine for a relaxing listen)....but I prefer off for most listening (they're actually behind the speakers leaning up against the wall). The more I listen the more I'm impressed - I think it's the NaimFrontend/el34/TannoyDC combo that works really well together (although vinyl is where these have had the biggest improvement - to the point that I'm listening to more LPs than CDs currently). I'm not in the least bit inclined to change from these and feel they'll be the last speaker upgrade I do - but if I were to consider it in the far distant future, pepperpots is where I'd go ......just sayin'

    Thanks - they sound better the more I listen. They even excel at “busy” tracks which with previous speakers became a “wall of sound” - chucking things like Pigeon Detectives or Prodigy “RokWeiler” doesn’t trouble these at all (and boy can they rock) All I can say is Thank you - I can tell they’ve been well looked after by you and Zouch Audio have also been great. Not only was the price reasonable (I’ve seen grottier examples for sale with damaged cabinets/grille/scratched front treble plates etc etc for more than 2.5k) but delivery was too (£100 which given the size and weight was not unreasonable I thought). My previous thoughts on the sub were correct, after recalibrating, REW shows that it simply fills in the lowest octave (40Hz and below) and subsonics (you can feel the bass) but also it fills in a 90Hz room dip nicely (adds about 10db) whilst not exacerbating the 110Hz mode. I can happily listen to most tracks with it turned off though. The trace happens to be flatter than any other speaker in this room but I’ve only done a few quick sweeps. The treble is more interesting on REW though. The front plate does exactly what it says on the tin in terms of gain and interestingly the grill is pretty much a 1.5db cut when in place - so the trace with “grill off and neutral treble” closely follows the trace with “grill on and +1.5db treble” albeit with a few variations along upper mid and treble - which explains the slight difference the grills introduce (slight treble cut but also vary slight change in presentation). I have them off for listening as vocals and instruments sound more “there”. That’s not to say they sound bad being on - merely a bit more laid back (a bit like my old Quads in general tonality) and actually perfect for night time listening.... ....and that’s another thing I love about them, I can listen at very low volumes and still hear ALL the music, rather than having to turn it up a bit to get that balanced sound. I’m at work now but I think my custom stands have arrived so I’ll see how they are when I get home tonight (if they’re bad I can always leave them off and repurpose the stands for use elsewhere in the house).... Sent from my iPad using Tapatalk EDIT: Yes, my new custom stands have arrived : No more wobble than on the floor (which isn't suspended, it's engineered wood on an underlay on concrete) and just the right size. Tweeters are now at ear height when sitting down .

    Tannoy Prestige Stirling GR or ATC SCM40 ?

    Look what came today (yes, delivered by Zouch Audio): Firstly, WOW..... the sheer amount of detail being thrown into the room by these far eclipses the Precisions. The pin-point imaging remains but soundstage is even deeper. Listening to a lot of CD's and I'm noticing things I never did on tracks before. The biggest improvement I've found is with live recordings and things like piano and guitar strings sound amazing now like they're being plucked in front of you (even non-audio folk like my wife and brother noticed the improvement right away). Not only that but the speakers are in Fantastic condition (don't know what the previous owner used but the Tannoy Wax jar remains sealed). The great thing is I can chuck these right against the walls and toe them in slightly with NO detriment to the bass. The Speakers produce much faster and tuneful bass than the Precisions and I've had to turn the sub right down to 40Hz XO (the Turnberrys go to 39Hz I think so just about seamless) and the BK won't utter a peep unless it's called for (EDM/DUb etc).....playing some Bob Marley and the sub hardly moves with most of the sound coming from the Turnberrys alone - play some Rüfus and they start pumping out deep bass you can feel. So I think the sub stays (it's only on 1.5 notches gain but I notice/feel when it's not on with certain genres - otherwise it sits there doing nothing). I also have to recalibrate my brain to what loud is on the PrimaLuna vol knob. Invariably putting the Amp to 2 notches (I got used to this with the Precisions) is FAAAR too loud - I have to keep turning it down . Grills ON or OFF? ON sounds very slightly less "airy"/more "closed in" even if you put the treble energy up a bit to compensate but this could simply be because the tweeters are slightly low and therefore off-axis. For the time being the grills stay OFF though with treble energy set at neutral... I would like some stands to bring the tweeters up to ear height but don't fancy trying to get hold of the RFC ones - I'm getting some "custom" ones delivered soon and will update the thread when done. After the stands arrive I'll recalibrate the Sub with DSPeaker and run REW to tweak things a bit more (although the fact that these simply sound so right from the off means I hope there's not too much to do there).

    Ok so I have done some rearranging in preperation for the new arrivals: I've made it symmetrical with roughly 63cm either side - hopefully this will be plenty of space for them. The sub is slightly more into the room and away from the wall which according to REW room simulator should improve some room modes a bit. The VCS is now side-on giving more space on the left. Speakers arrive Monday and I'm hoping that's enough space for them as I think that's the best I can manage

    Tannoy Prestige Stirling GR or ATC SCM40 ?

    That's a fantastic idea ......why didn't I think of that - I think plants behind them will make the room look nice as well so will have a look in some garden centres at the weekend. Too late - they're arrirving Monday . The Precisions were about 5-10cm further in each side and you're right, that improved the bass and midrange reinforcement (ie reduced it)....but also worsened soundstage depth and width. I was forced to put them where they are now (in the picture) as the VCS needed to go somewhere. As mentioned after a lot of fiddling (e.g. port blocking, adding 1st order XOs etc) I have finally got them sounding great - the Turnberry's are therefore more to scratch an upgradeitis itch than anything else. If I can place the VCS elsewhere, that will give me more room to bring the Turnberry's further in - i'll need to experiment when I get them and am considering having the VCS and sub on the outside if needed.....I'll only know after I unpack them.
