Have you looked at the Musical Fidelity A300 or A308? Both should be availabe for under 1000, and at 150 watts at 8 ohms and 240 watts at 4ohms they should be enough to drive your speakers which are quite efficient.
Integrated under 1K new/used
I am looking to go the integrated route. Presently running a Adcom GFP 565 and Adcom 5300 Amp. I am open to tube/SS options, Jolida, Portal Panache, Krell 300il are a few that spark my interest. Any others? I will be powering Monitor Audio S8's.Other associated gear is a Denon 2900, Musical Fidelity X10 V3 and Kimber 1010 and Nordost Red Dawn I/C's and Kimber 8TC Bi-wire Speaker cabling. As always, input would be appreciated.
