I'm currently running my Martin Logan Summits from my much loved EAR 890 Valve amp. I'm hoping (one day...) to take delivery of a set of John Westlake's VFET power amps which are going to be developed specifically for this type of speaker, so I have a final solution, but I would quite like to release the invested funds in the EAR for other things, so I was thinking about building a small power amp to use in the interim period.
My kitchen system is a three way active speaker and I use two T-amps for the mid and treble, and a pair of Gainlones that I built maybe ten years ago, that used to drive my Quad ESL57s in my TV system.
I've tried the Gainclones on the Summits and they sound good, but I'm not sure how well t-amps will cope with the extremely low impedance at high frequencies.
I'd like to build an amp that has a balanced input and is relatively simple to construct. Ideally I'd like to re-use some PSU components I have in stock as well, to keep costs down.
I'm sure someone is going to suggest N-Core but that is too much money.
So, should I just build a balanced Gainclone, or should I be investigating class D - T-amp type of technology, as they seem to be available as ready built boards quite cheaply.
