Introducing myself to the group. My electronics are mostly common. I built an EICO amp, Dynaco PAS3X moded. PAT4 I built. AF6 I built. Dynaco MKII's moded by me. Moscode 600's moded with Mundorf caps. I am an electrical engineer with ears. I am not a business but if you need help on a Moscode I can replace FET's, match sets, tell you how to adjust idle current, DC offset and High Voltage DC.
I mix old and new technology. I have a music library saved on hard disks as Wav files. I send the music out via fiber optics in SPDIF at 96K from an old Toshiba laptop. The SPDIF feeds my TriVista DAC with tube outputs, upsamples to 192K, the preamp is a Parasound and on to the Moscode and Martin Logan Summits. The Parasound is a concession to supporting 5.1 Video. with a second moscode, older ML stats for the rear and ML center driven by a Dynaco MKII. The Depth I sub does not require a amp.
So solid state from the 60"s tubes from the 50"s, hybrid amp from the 80's, DAC with tubes, laptop from 2000 (vintage right).
For me image is everything, when you can locate each instrument, play loud and not get ear weary the system is pretty good.
Tubes are not more accurate. But their distortion is pleasing, a rounded sine wave (tube clipping) sounds like the second harmonic was added... warm sound. A SS amp when it clips, the sharp edge produces a whole series of high freq. transients you know don't belong. How do you make SS amp sound good? Build it with so much range that it never clips.
So much for my first post
