Schubert, since I had a window at the first reflection point there isn't much I could do. The blinds are Hunter Douglas duette architella dual core blinds. I wanted to do something on the bottom besides an acoustic panel so it wouldn't get too dead. I found the design from Argen Sound Diffusers and it is made out of 3/4 inch birch plywood. It is actually three panels that I hung on the wall with the 1/2 round trim strips at the joints. It was a fairly easy DIY project that used about 1/2 sheet of plywood and the 1/2 rounds came from a store that specializes in trim and moldings. I think it helps break up those first reflections.
Spencer, I listened to a lot of speakers (up to $30k) before I decided on these. These were the ones I had the best emotional connection with. I really don't have any complaints about them and I think they will be with me for a long time.
Bdp24 those are the older Herron M150 mono block amps that have been updated to the current M1A amps. The great thing about Herron audio is that he can update older product to a current configuration for a nominal fee and his product sounds great and he is the best to work with.
Milpai, since this was at the first reflection point, I decided something under the window was better than nothing. On the opposite wall is a raised panel door.
I will be updating the room pictures when I purchase some new speakers. I may change the panels after further listening. The center panel has been replacef by a diffusor and I have added a small wood diffuser to the right side of the room under the window. I am limited in really treating the first reflection points to my satisfaction since I have a door on one side and a window on the other. I have changed the window treatments to double honeycomb core blinds. All in all the room sounds pretty good for the limitations I have from the listening position.
Garebear, My Avalons are spiked directly to the floor. I haven't experimented with any other material under the speakers. What have you discovered using the granite? At some point I'm going to change our my speakers. There are lot of things I like about the Avalon's but I'm going for my "last" pair of larger floor standers. Perhaps, Rockport, Magico, Verity or Acoustic Zen's.
I have a few guitars a Martin D-18V custom, Collings OM1AC custom, Fender Eric Clapton custom shop Stratocaster and the G&L ASAT. The amp that I am using now is the Fender Mustang III. It's a great little modeling amp is perfect for hauling around and jamming with my friends. I will be getting another quality tube amp at some point and am really interested in the Vintage Sound Amps. I had a Swart tube amp and sold it to fund my Collings guitar. If you have a chance to play a Collings guitar I would highly recommend them. They are expensive but sound fantastic!
Sorry I didn't get back to you sooner but I haven't checked this page for a while. I really like Herron audio equipment. I didn't compare it to the Pass Labs offerings. Prior to the Herron, I was using McIntosh equipment and find the Herron equipment to be superior in sonic an build quality. One of the things I like best about Keith's company is that you can actually contact him and he is very responsive to questions. He has upgraded my amps a couple of times to bring them to his current configuration. You don't find that very often and the upgrade price was very resonable. I would stick with Keith just for his customer alone and it's great that his product sounds excellent
I have not read Dr. Floyd Toole's book but thanks for the tip! I thought of covering the glass with drapes but the cosmetics just didn't work. I have thought of changing the blinds to the newer triple cell type for some diffusion enhancement. The acoustic panels are all two inch with the exception of the corner traps which are four inches. I have listened to the room from no treatment and rugs to it's current configuration and agree that I don't want any more absorption. I have thought of replacing the rear center panels with diffusers. Trying to find diffusors at a resonable price to experiment proves to be difficult. If anyone has a suggestion on the best way to "experiment" at a reaonable cost, I would welcome the suggestion.
