I might suggest a BAT VK-200 amp and Kimber interconnects.
SS amp for Audio Research LS-16 pre-amp
I'm leaving HT and going back to stereo. I have an Audio Research LS-16 (tubes) pre-amp, Audio Research CD-2, NHT 2.5i speakers, with JPS Superconductor speaker cable and JPS Superconductor II interconnects. I'm looking for a solid state amp. I've been looking at used Bryston 3B-St or 4B-ST. Any other suggestions? Also recommendations for balanced cables?
