Hey I designed a DHT preamp. What I was striving for was real sound to me. frequency extension, beautiful mids, soundstage height and depth, placement of instruments, layers of details without the typical audiophile sterile sound, etc. How am I trying to get there? I tried numerous chassis designs with wood, metal (aluminum, steel, copper) and different thicknesses. Tried four or five different output transformers before deciding to wind my own, caps, resistors, wire, different tubes old and new, all types of volume controls, interstage transformers, power transformers, single stage design, two stage design, tried battery power designs, etc. Three years trial and error and comparing to other manufacturer designs and in other peoples systems. I have learned how each part of the design works. But it also comes down to mixing and matching some of the parts to see how those combos work together. Three years in the design and I am almost to the point where I feel there is not much more room for improvement. I am close to as perfect sound that I think everyone would like to hear from a preamp as I think I can get. I also think that everyone has a sound they are looking for and mine may not be that sasme sound. I built into the preamp a switch that you can change / taylor the sound to your system in five ways, sort of the way cables change the sound.
Is this what you would be looking for from the designer?
Happy Listening.
