Sorry to be a bit thick, but would I be right in guessing that this wee box goes between source and amp?

Tempted to ask for a dem with my Worst Room In the World, Evah . 3 walls (the 4th "wall" is open into a double-height atrium. One of the 3 remainiing walls is glass. Wooden floor with a single rug. Sparse furniture. Drunken, angry owner.

Well done Jack, room correction can make the biggest single improvement to any system, because it deals with the one component that you cannot swop, the room!

KR Keith.

Gyro yes,between source and amps.

I have to be honest and say I have wanted to try this sort of unit ever since I read about an original one devised by AR many years ago. I also read the articles about the Lyngdorf and TAct units and wished I could have at least heard them . Sadly never had a local dealer who stocked anyhting like this. Would really like to try it out in my room but I am little too far away . Will read the results with interest and if you ever decide to offer a unit for home trials let me know.

I know these type of units often come with a mic to use for setting up but anyone I have talked to has always said if you get a better really good mic to use then it will make a difference is thsi the case ? Or has the unit been carefully calibrated to the mic supplied and takes in to account all the mic faults (they all have them just some worse than others ) .

I have a Berhinger DSP pro curve, will this do the same as that? its for control of the bass on my open baffles. what sise is the unit and would i need the stereo one for the bass drivers?

Yes I believe the Berhinger does a similar job, this unit is 9 X 6 X 2 1/4 inches. You would need the stereo unit for the bass control or the Dual core if you wanted to deal with everything.

I would think a high end mic would offer a more accurate measurement but am yet to test this, I know of a few members with mics suitable so I may enquire to borrow a unit or two for research.

As for home trials/demos I am so confident in this product that I will offer a 7 day money back guarantee. If you have room problems this will fix them - fact.

Jack looking at the unit it also has a digital in and out so can you just connect it that way directly into your DAC or is the other way round you Dac to the unit then out ? Shame if does go that way as keeping all of the work in digital form as long as possible would be sensible.

Hi Andrew, the unit is a Dac and has digital in and out so can be used either way, I'll try and give you more info later this evening as I am out on site all day today.

Thanks, Jack

Jack - considering you are working on site it was nice of you to even bother to answer. Do not worry I am sure I can read all that I need to through the mfg website you just concentrate on doing what you need to .

Really interested in this as one of my bugbears about modern hifi is the elimintation of tone controls on most amps. Just think of the amount of box and cable swapping that might be avoided if your existing boxes gave you more options to tweak the sound. This looks like a really neat and sensibly priced solution & would love to try one (or a similar device) when funds permit.

I have had one of the Dual Cores for a couple of weeks now. Unfortunately I've not had much chance to play with it, but it is dead easy to set up and works very effectively to remove boom. I am only using it on the base signal and could have got away with two 8033s units (the pass band on the original 8033c was too low for me), but the additional cost for a Dual core was not much and it is much more flexible.

It could also act as

- a pre (with room correction, tone controls, and optional subsonic filter)

- a DAC (with room correction, tone controls, and optional subsonic filter)

- a DAC+Pre (with room correction, tone controls, and optional subsonic filter)

- DSP between CD deck and DAC

You can also set high-pass and low-pass filters (customisable), so that you could have one dual core per channel for active biamping in any of the above configurations. I believe it will be possible to link units with theforthcoming firmware releases.

exhausts all the possibilities. My only complaint are:

- that the mic lead is a little too short, so I'll probably have to get/make and extension.

- The maximum input voltages (1.65V RCA and 1.35V balanced) seem to be a little low given CDPs output 2V. However, I've been told there will be an option to attenuate the input signal on the next firmware release,so these limits will be approximately doubled.

I have to concur about the price offered here; it is a fair bit cheaper than buying it on line from the manufacturer.

Just had confirmation that I will be sent a firmware fix for the input voltage on Monday, If you would like me to send it to yourself drop me an email and I will send it across with pleasure.

Now where have I seen that before. Thanks for coming over today Jack, I think you'll agree we had an interesting time this afternoon. All in, a good result, certainly had a great affect on the bass hump in my room.

Thanks for bringing the Ming Da Phono Stage too, I'll have to have a longer listening session with that once I've got my TT sorted. First impressions are very good though.
