Absolute top tier DAC for standard res Redbook CD

Regarding acoustic treatments: I consider the absorbing side panels the #1 priority. Put a mirror on the side walls if you have them and when you see the tweeters from the listening position this is where you put them. I recommend the absorbing panels with graphics from GIK acoustics:

As for bass and imaging, I recommend the 1/4 round tube-traps in a height that matches your speakers. These not only tame bass, but by acting as inner scattering devices, they improve imaging significantly by scattering the inner back-wave from the speakers. You position them inside and just behind the speakers with the round surface facing inwards.

Based on my experience I have to agree with Steve about treating 1st reflection points. I am simply amazed at the improvement in sound I am getting. I should have done this a looooong time ago!

Matt, I suspect that you've made a good decision regarding the single heavy gauge dedicated line. As a point of info regarding the 2.8 amp measurement, though, I would by no means assume that an electrician's current meter necessarily (or even probably) has sufficient bandwidth (i.e., is fast enough) to capture the narrow high amplitude current spikes that are likely to be drawn by the amplifiers at times. Especially in the case of Class D (and also Class AB) amplifiers, whose current draw fluctuates widely with the dynamics of the music.

On another note, let me add my second to the many expressions of appreciation that have been made for the time and effort you are putting into performing and writing up this effort, which is and will be of considerable benefit to many.

APlhifi-usa, Hi Alex, thankyou for the post to me, this is exciting news, I got rid of pre-amps many, many years ago!, I run direct to amplifiers now with my digital, interesting technology about your volume control, I have seen over the last couple of years the digital sources running direct to amps, and pre-amps close the gap of performance because technology with volume controls have got alot better, I do not have a record collection, although I love the sound of analog, I do not have other sources, I will be building a second system for multiple sources at a latter time, I have cables for the second system now, currently, I am still building my main system, the digital I have now is quite engageing for what it is, it is temporary, this cd-player will go on second system, I love the sound of it, however, I want a world class digital componet to run direct to my amp to keep the signal intact and as pure as I can get, The ODSE and your APL DSD-S fits the bill for running direct, that is my sole purpose of keeping up with this thread, so Alex, what transport do you recommend for your DSD-S dac?, thankyou.

matt, you are doing a fine job!, this has been a wonderfull thread to me, a great learning exsperience as well, alot of the brands you have brought to the table were unheard of to me, I'm an ex musician, so do not take this the wrong way, This thread is cool!, Bravo and cheers to matt!, Thankyou for taking YOUR time out of your life to do this thread, you, by no means did not have to share this journey, I will never forget this thread!
