@tomic601 I build my own components so I can use any parts I want and have tried most of them. My DAC is a directed heated triode design with a 30lb separate power supply. My website is not complete but you can get some info on vujadeaudio.com There are some links there to the CAF and you can hear a little of what the DC sounds like. The current amp I use on my Vandersteen 5s is a 100wpc bi-polar transistor hybrid power amp using (4) 6DJ8 tubes, filter choke, Nichicon power supply capacitors, V-Caps, Shinko and Caddock resistors. I also built the M5-HP filters for my Vandersteen that sound better than the Vandersteen filters in a quick comparison test. The person who let me into their home to hear the Vandersteen 7s has asked me to make him the DAC.
Happy Listening.
