I'll second Newbee's suggestion of the Sonic Frontiers SFS-40. I ran some fairly inefficient speakers (86db) with one in a small room with great results. The best part of this amp to a beginner (or a veteran) is the flexibility of tubes it can run - kt88, kt90, kt99, 6550 or el34 in the output stage and in the input and driver stages - 6922 or 7308. And those are just from memory, I bet there are even more options. Great for tube rolling and finding out which valves suit your tastes.
Beginners Tube Amp Recommendations
I'm seduced by the liquid sounds of tube amps but need some good recommendations on where to start. I'm looking for an entry level tube/hybrid amp around the $500-$700 new or used. My speakers are Totem's rated at 80watt & 4ohms. I've checked out Jolida 102, AMC 2030...anything else? I don't wanna spend a bundle just to found out that tubes are high maintenance and then want to go back to SS amps.
