M,Any update on the PS? I'm (very slowly) working on a couple of GC projects right now. Last weekend, I dropped into a surplus store, purchased $10 of caps and resistors, built a snubberised filter and tested it out on my new GC.
I can't give a detailed comparison because there are too many different variables between this test unit and my normal GC. However, I can report that the bass is much more solid. And this is only with a 15+15 25VA transformer. Can't wait to plug in the 22+22 225VA that I have on order.
There doesn't seem to be any degradation on the mids and trebles, but like I've said, I haven't done a direct comparsion.
On a side note, I still surprised how big the gap is in sound between the GC and commercial receivers. Last Christmas, I replaced by 5 year old $200 Sony HT receiver with a Yamaha RXV1500. The Yamaha is still entry/mid level, but very well built and was a big improvement over the Sony. Even musical when you enable the STRAIGHT "By-pass All" function. But the GC's still miles ahead. Luckily, the receiver has Pre-Out function, so it gives me a big incentive to complete a five channel GC.
Gar.
