To Jeff Fritz
I can fully agree with your statements in your recent article “TWBAS Is Back! (Not Really).” However, I missed some information about the most crucial component of a stereo system: the listening room (and the quality of the mains power supply, of course)! Can you give us an idea about your listening room that serves for evaluating the speakers? And some comments on basic requirements and room treatment? I have had some of the finest speakers in my listening room, but the sound quality never did reach the quality heard in the dealer’s giant demo room. However, some smaller and near-point-source speakers performed fantastic.
The easiest way to learn about my Music Vault listening room (23’ 6” wide x 20’ 1” long) is to read “Music Vault 2.0 and the Value of a Reference Listening Room.” In that article you will see three links to articles that detail the original construction, which was back in 2005. The room was professionally acoustically engineered by Terry Montlick (retired) of Terry Montlick Labs. In the three articles mentioned, you will see photos of the room as it is being built; the CAD drawings, which show the acoustic design as modeled by Terry; and measurements and listening impressions of the finished product. In 2012, I made some modest adjustments that improved some small details -- these are also explained in the article linked above. You will also see a photo of the Torus Power WM100 BAL, which is a 100A transformer-based power-conditioning unit that is wall-mounted in my room. This supplies two 20A outlets and four 15A outlets.
Suffice it to say that I agree with you on the value of a proper room. Everything you put in the room is colored by it; a neutral space with which to evaluate gear adds a significant dose of credibility to the findings. If you have any other questions after reading the article above, please do not hesitate to ask. . . . Jeff Fritz
