Absolute top tier DAC for standard res Redbook CD

Yes, double rock with Green Visco-Elastic glue spread thin in between. Glueing rock to studs as well. I was planning on staggering seams. I like the idea of flipping the rock 90 degrees.

I plan on treating corners with bass traps, 1st reflections with duffusion, and front and rear center walls with a combo of diffusion and absorption to reduce slap echo. Gonna float a "cloud" of diffusers on the ceiling in first reflection but need to establish seating and speaker location first. The first reflection diffusors need to be 4-6" deep and horizontal diffusors only. Front and rear to be shallow diffusors in both the vertical and horizontal plane.

My room has absolutely no furniture or cabinetry besides the listening chair and my rack, and speakers obviously. The rack will be located just to my right on the adjacent wall and a scotch behind to avoid any interference with primary or secondary reflections.

Alex, that's a cool product.

Thanks Al. I was looking in the 2014 buyers guide. I guess I don't get that with my subscription...

Matt - another thing I did in my listening room was stagger the footings and support pony walls under the floor, so the floor was not supported in the middle, causing a second harmonic in the floor.

Also, I used two layers of 3/4" MDF on the floor, glued together, staggered and screwed down, much like the walls of a speaker. It has thick carpet over it. The walls of the room are also sound-proofed to some extent. One has plywood under the sheetrock.

Steve, great advise. Matt, the question I have is where in the house are you located and how high is the ceiling? The dimensions can be just as important as the floor. Are you on cement or studs? now that you bring up the studs, yes, we made staggered studded walls for the rock. I just realized that. 2x6 construction too if I recall correctly.. It's been a long time though, but I remember staggering everything we did. We too glued everything. I remember when we set the room up for the first time, we realized how little treatment we needed. He had the Michael Green ceiling deals in the corners and that was it for the ceiling. He used a swirled ceiling to break things up. Sound stupid, but I actually think it may have helped as I've been in rooms with smooth ceilings and they were a bit too live for the systems that I've heard. Nothing wrong with a popcorn ceiling either. As we all know you can go into a room and set up your system and hear where you need some help. Sometimes you can over damp things and one problem cleared up can create another. that's why I like quilts, large plants in corners and racks of records or a diffusor type of deal in the rear. Everyone has preferences, but all too often the 'professional' rooms are way too damped and lose some timing and pace for me. I hear it often in stores too. one other things I'd recommend for your electrical is to have totally separate and grounded (to earth) circuits for EACH outlet. I did that and it makes a huge difference. I don't use a lot of special stuff for my electrical as the Ayre components have their own built in and that's how they want it to sound. I haven't even found power cables that I love yet. We've AB'd many of them and most have cut the leading edge or messed things up rather than help things. JMHO

Most professionally done rooms sound like mausoleums. That works well for recording studies but does a poor job recreating a palpable auditory illusion that we all want. Michael Green was ahead of his time, and I know quite a people who have incorporated his tricks to good affect.

I too have dedicated lines with with isolated earth (ionic) grounds.
