    DIY Subwoofer

    Isn't the SVS system the same in this regard? They both specify using a 2.4 GHz signal? I can't see why not. No harm checking with Monitor Audio though. Is your amp an A-S801? I was just having a nose at its manual. At the risk of asking a dumb question - have you experimented with boosting the bass with the tone control? The sub output rolls-off at 90 Hz, which is fine but worth bearing in mind when thinking where to set any cut-off frequency on a sub. Looking at secondhand prices would be a good guide actually. Searching for Sold items on eBay may be informative.

    System advice please!

    I'm afraid my thought is that I know nothing about vinyl playback paraphernalia . I will though add that having speakers as the most expensive part of a system is generally as it should be as far as I'm concerned. Certainly for digital playback anyway.

    DIY Subwoofer

    I'll be honest I'm still a little unsure where you mean to place the sub. Corner placement will give maximum output but not necessarily the flattest response at the listening position. An Anitmode allows this to corrected to some extent, and I think a miniDSP could do better (but is harder to use). What you really want to avoid though is a frequency null at your listening position, since no room 'correction' can fix this. The only option is to move the sub and/or the listening position. I guess that was a long winded way of me saying that some flexibility over position is good . If your room is at least approximately cuboidal then the Room Sim feature in the free to download Room EQ Wizard would allow you to get some idea of what your intended spot would be like. What are you speakers? Your Info says 'WA Allegro' but I can't work out what they are? My first thought was Wilson Audio but my Googling hasn't found an Allegro loudspeaker. I was trying to find out what sort of bass extension they might have? The potentially trickiest bit with subs is how you integrate them with the mains speakers. In terms of wireless signal connection, Monitor Audio make a cheaper alternative to the SVS wireless kit, which going by this post works perfectly well with subs: They cost £70 for a pair: Have you used a subwoofer with stereo speakers before? I'm only asking as my gut feeling is that if you go down the DIY route there is reasonable risk of you ending up with something that you don't like that has little resale value. A second hand sub to at least try out first might be worth a try? Just a thought. Not trying to derail your thread! I'll shut up now .

    The obvious question is why change anything then?

    Ed Selly reviews the Kii THREE

    Something tells me the speaker positions in the review photo aren't entirely optimal .

    DIY Subwoofer

    FWIW a downfiring BK Monolith can work like that. My sister happily popped her ipad on top of mine next to a chair without realising what it was . The wood finishes definitely help. Dimensions are a little bigger than your ideal though, at 60 cm (H) x 54 cm (W) x 420 (D). (The plate amp and all connections are along one of the 54 cm long sides.) I'm sure you'd have more fun making your own sub but are your DIY skills up to making a good looking cabinet? Edit: whether the spot you have in mind is a good location for the sub to work well may be a relevant factor BTW, especially if you aren't intending to use any DSP to manage room modes.

    Impressions of KEF LS50?

    FWIW the LS50 wireless model does have a single analogue input as well, so it isn't completely restricted to digital only use.

    Digital Source Question.

    For balance: playing music CDs is different to simply transferring data since it is read and played real-time, with timing variations (jitter) having the potential to affect the sound. There is also the possibility for electrical noise from the transport to affect the DAC. My personal inclination is to believe that a well-designed DAC shouldn't be significantly affected by either of these but I don't know enough to totally discount it, and there is obviously scope for poor DAC design to make a particular model more sensitive to these factors. Many years ago I was at a bake-off* where we switched between transports at one point and all definitely thought we heard a clear improvement. This was however a sighted test and I'd now want to hear such a comparison un-sighted to be convinced this was real. Where I'm at with transports personally is that I suspect it's unlikely they make any significant difference but I don't feel I can categorically discount it. For myself though I'm currently focusing on much more significant changes to sound at the speaker and room-acoustics level. Last night for example playing about with a sub and miniDSP to go from a ±15 dB variation to ±3 dB from 20 to 100 Hz. I mention this purely for perspective when considering possible differences between transports. Depending which DAC I've used recently I've changed between either an OPPO blu-ray player or Pioneer Stable Platter CD player as transports, with the choice dictated by whether I want to use an optical or RCA SPDIF connection. I prefer using the Pioneer because it is faster to operate. I have no plans to rip all of my CDs to a networked hard drive, primarily for reasons of time and cost for no significant up-side. FWIW the measurement-based DAC reviews from the likes of ASR do test significantly more than simple frequency response. They do though still have to pick a subset of all possibilities to test of course. *Hosted by the founder of this forum IIRC.

    Digital Source Question.

    To prove a point, here is a mains lead you can buy for your HiFi for £3300: They've even had the gall to register the name 'CopperConn' for their copper connectors .

    Digital Source Question.

    Bear in mind selling HiFi equipment is a business. People will sell products they think there is a market for, at prices they feel they can make a profit from. Just because someone makes and sells a £2k CD transport doesn't tell you anything one way or the other about whether there is any benefit to buying one.

    Wanted: Audiolab Power Amp 8000SX

    I'm pretty sure the gain of the 8000P will be the same as the 8000SX, and this is what matters for matching rather than the (maximum) power. (Although do try to confirm this if you end up considering an 8000P.) I'm only mentioning this as I suspect you may find it easier to find an 8000P.

    Wanted: Audiolab Power Amp 8000SX

    Out of interest, any particular reason you want an SX rather than the more powerful P model? (I have and 8000P sitting in a box upstairs, but only one channel is currently working. Not looking to sell it though.)

    Power Sound Audio Subwoofer in Stereo System?

    (You posted the above in the Bits n Bobs thread but I thought I'd reply here.) From what I've read I believe the S1510 should significantly outperform even a Monolith Plus in terms of peak levels and low frequency extension, despite it's smaller size. I'll be honest Sunfire is a brand that wasn't really on my radar. I'll do some investigating .

    Anyone going to try the upcoming Okto dac8 ??

    If you were local to me I would actually have been interested in having a listen to your Bel Canto. It wouldn't offer the functionality I have in mind though.
