Hi Guys.
I am not on the forum as much as I would like, but I thought I might address some of the comments made regarding my set up.
First off, it was such a pleasure to have Lou grace me with his presence here. He is a great speaker designer, a true gentleman and a friend. He makes one hell of a cabinet, too.
I have many holes in my carpet from obsessing about the perfect speaker position in this room for these speakers. It has taken a long time to get perfect, but I'm pretty sure I've got it now. Inches make a difference in speaker placement too

First off, the speaker bases are spiked to the floor and there are rubber pads, much like the rubber/cork/rubber pads advertised on Audiogon, but larger and w/o the cork, between the bases and the stands, which I keep mistakenly calling slabs. I believe this is what Lou now supplies with the speakers as long as the stands and bases are ordered.
The room is 23' long x 18' wide. The ceiling is 8 1/2 feet at the front and 9 feet at the rear. I have a lot of absorption on the side and front walls and a lot of reflective devices on the back wall. The first side wall reflection of both speakers are absorbed by 2" thick fiberglass panels.
The front of the speakers are about 74" from the back wall. Any closer to the back wall shortens the depth of field. Any further out into the room gets them too close to me for the spectacular imaging I am able to get. They are only about 30" in from the side wall and as long as the first side wall is absorbed, which is the case here, the soudstage is wide, natural and very well defined, without any loss of center fill. I have them canted inwards, so that they are very nearly pointing right at me, but pointing at my ears, as opposed to say, my nose. Maybe because of the offset tweeters, pointing them right at me or close to it, does not make them too bright. Conversely, pointing this way, duplicates the way live music sounds to me. They are 13 1/5 apart from one another, measured from the center of the cabinets and about 14" away from me. Jim's suggestions might work in some rooms, and I do appreciate his input, but not in mine and not with this MTM design. I'm pretty sure if he heard what I hear, he would like it a lot.
As for tubes, I swap equipment around some, but there are some tubes in the system. The Pass XA100.5's, Marantz SA7S1 and Herron VTPH-2, which has 5 tubes, stay in the system 100% of the time. All are great sounding stereo components, in my opinion. I also mostly use a ModWright LS36.5/PS36.5 preamp which also have tubes. No tubes, but my analog is a SOTA Cosmos Series IV, Origin Live Illustrious arm and Miyajima Shilabe MC cartridge. The cartridge is run unloaded into the Herron. Am important part of the sound quality I get is due to the Dynamic Design cables that Lou introduced me to. These are fabulous cables. I also use a 20 amp Furman Balanced Power Conditioner and a few other tweaks.
I listen to all types of music from rock to classical, but it is mostly rock, jazz and classical. I do not have any Opera, although that is mostly because I wouldn't know what to buy.
If anybody in North Carolina would like to visit for a listen, they are welcome. Please contact Lou and he will put you in touch with me.
