![]() ![]() The amplifiers are notable for their elaborate power supplies, component quality, casework materials and for not using negative feedback (NFB). I have been designing high-end 300B tube amplifiers for over 25years. I thought a NOS design was a good place to start. They usually have cleaner, sweeter treble than DAC’s with over-sampling. In my experience R-2R NOS DAC designs usually sound refreshingly open and natural rather than processed and synthetic. Information is one thing, but it needs to be presented naturally with recognizable timbre and tone. Lots of DAC’s have dazzling specs but sound machine-like and obviously digital. #Cd label software boeder payrol free#GD: I was aiming to make an affordable DAC that sounds refined, clean, relaxed, fluid, colorful and human and free from the artificial ‘hi-fi’ sound that characterizes so many budget designs. Anyone that thinks the chassis material does not play a part in the sound of a product hasn’t done the work.ĭS: The DAC SE uses a ladder DAC in a tube circuit. When I realized I could use copper casework for the DAC and still make it relatively affordable it seemed like an obvious think to do. ![]() I had copper chassis made for my amplifiers and the difference was clear. He spoke about calmness, tone color, quietness of background, noise floor (audible, not measurable) and freedom from grain. He told me it was not for looks and that copper sounded better than steel and aluminum. We discussed amplifier design and I asked him why he used copper for the chassis of his amplifiers. I was lucky enough to hear amplifiers made by Audio Note Japan and to meet the legendary late Mr. Aluminum by comparison sounded lighter, more free and more airy but was also somewhat frenetic and unruly by comparison. Steel imparted a glare and grainy character to the sound. There was a noticeable difference in sound between the two. Early BorderPatrol amps were made with steel and aluminum chassis. Gary Dews: The use of copper for the casework was a spin-off from the BorderPatrol amplifier designs. Since Doug has given us a break this time by writing a sub-8,000 word Review, we’ll let him off.ĭoug Schroeder: The DAC SE uses copper for chassis. Per Doug: “Do not mistake brevity for lack of enthusiasm. This review is separated into two parts, namely a Q&A section, followed by the review observations. Publisher’s note: Doug Schroeder, in conversing with Gary Dews, owner of BorderPatrol, found him “perfectly polite and technically succinct,” which inspired him to write this review in the style of notation form of the Owner’s Manual. ![]()
