Sorry for not being more clear - I should have kept it short. Not sure why Frank is getting defensive, I'm not trying to attack him or any manufactures and apologize if it's coming off that way. Frank is right, I was confused about which amp I sent him, because we actually sent him both. The first one (my personal unit which is white) we had to stop the shipment mid stream at Franks request since he would not be there to take delivery. I then sent him the first production unit so he would not have to wait for the original amp to make it's way back here, be unpacked, tested, repacked and sent back out. That said, it makes no difference which one it was, the point is simple. My original choice was to sell the amps with a 100 ohm resistor to limit the power. Frank didn't like it. I lowered the value to increase the power into headphones and then he liked it. The sound of the amp didn't change, it just gets louder now. So the solid state amp didn't actually sound better, it sounded louder. I suspect the same is true of the more powerful 300B amps. Remember, just because something costs more doesn't mean it sounds better.

P.S. Just to nip a lot of CSP2 questions in the bud, we are coming out with a black plate CSP3 and there will be a price increase. Anyone on the list for a CSP2 will be automatically upgraded to the CSP3 at no additional cost.
