"Dave is a audio stalwart and all around great guy who delivers. I have know him for about 6 years when he hooked me up with a pair of the little known but superb Brodmann F2 speakers. I created a new listening room and paired them with a pair of REL subs but could not get the sound right. He came out and spent 2 hours helping me get it right. He brought an audio spectrum frequency analyzer to find the best position for the subs as well as changing their room placement. He also discovered a standing wave which we could not eliminate but he was able to minimize the effect. He moved the Brodmann's in a few inches and the improvements were palpable and dramatic!
I also had a problem with "rumble " from my VPI Prime turntable. He immediately noticed how the motor's fly well was hitting the platter. He pulled it back a few centimeters and BOOM; problem solved and gone.
I can't recommend Dave enough. "
