Peter from Calgary, Canada built two amps and a linestage based on my concepts during last year. He sent me this nice article which describes his journey:
I do not consider myself an audiophile; rather my wife and I are avid music lovers who listen to music and radio throughout the day and evenings. I started with a B&W and Rotel combo based on What HiFi review. I then moved to Odyssey Kismet gear with a SlimDevices Transporter at the front. This was a big step up in sound quality, but not completely to my satisfaction.
Sometime in 2010 I was able to hear Shindo and Audio Note gear and was impressed. In May of 2010 I decided to build AN Dac 3 Kit and L3 preamp. I was able to understand my own sonic preferences and build something to reflect them. I have realized that I am in the emotion and flesh and blood camp.
I then came across the Lampizator website and decided to try some of his mods. Behringer 2496 mod was a revelation and made me sell my AN DAC. Squeezebox upgrades (super clock, separate PSs and tube buffer) made me sell my Transporter and buy Lampizator DAC3.5 (prototype of current DAC 4). In order to pursue SET amps I needed more efficient speakers and I opted for Lampizator P17 design (first with Saba later with Altec 755Cs).
I have also discovered Sound practices and started the search for a amp design/philosophy. This is how I came across Thomas and he happened to start VinylSavor blog just at a perfect time.
Why? I love Thomas’s design approach as outlined in the Gain/Headroom, and Power, Operating point articles. That, followed by power supply architecture and description of design decisions, just appealed to me. The fact that the amp would produce 6W, sounded better than some of the 300b amps, and utilized less expensive tubes, made it a no brainer.
