Thanks again to all for your answers and input!
Always wanted a little more power than my old Kenwood KA-405 55 watt integrated amp to drive my old ADS-L810's and now in a position to afford an upgrade. Just pulled the trigger on a Carver C1 preamp and a Carver M-1.0t with the switch on the back. Over the years I've read a bunch of stuff on Bob Carver, gear designs and some the challenges he gave to the "tube purist's". So looking forward to hooking these up! Would it be better to stack the amp on the preamp due to heat from the amp, seems to make sense?
