Yes, I have one and I agree totally with Steamboy. Actually, I first had him repair a good solid state amplifier. After he repaired it, he hooked it up to some Tannoy silver speakers which he rebuilt and are magnificent. It was like being in a mad scientist’s laboratory. Sure enough, my 150 watts per channel amp sounded fantastic. At that point however he took the same source and hooked it up to his little preamp which was only about 15 watts per channel. I thought mine was pretty fantastic however his sounded much better immediately.
My brother in law was in the market for a new system but I insisted that he visit David first. After listening to David’s system for 5 minutes, he asked him to build a system for him. Sure enough, it sounded fantastic to the point where I moved my system to my office and had David build a system for me.
Because it was a complete rebuild to my brother in law’s specifications, my brother in law encountered a few problems. He and I visited David and he sometimes would make modifications in front of us which showed just how smart he really is. Other times, he would take a few days but he never complained or whined about having to do it and never argued that it needed tweaking. On the other hand, my purchase was a little more sophisticated and accepted more inputs and the like.
The sound has incredible detail and people tell me they can hear things that they just cannot hear on their systems. I listen to primarily opera, more and more classical and jazz (since I purchased the system), a lot of female vocals and some rock. His amp and preamp cost less than $2000 Canadian (about 80%).
Since then he’s helped us get new (to us) vintage equipment which you would have to pay thousands of dollars for to get equipment of the same quality.
People come to my house and tell me that my system sounds magnificent. It sounds like the person is standing right in front of me (them) and there is both incredible detail and depth. At the same time, I do have a great set of Vandersteens so my speakers are really good. Still, he tells me I should get a set of Tannoy’s which I’ll wait to do as I recently purchased a set of Thiels so I’d like to take them for a spin first.
If my house burned down tomorrow, I’d buy another one of his units in a second. Oh, and his aesthetics have improved dramatically so they now look professional although it increases the cost somewhat.
