Check out Audio Aero Prima integrated amps. They are a hybrid design with a single tube preamp and solid state out. Very nice sounding amp. They do come up occasionaly (preowned) with prices well in your range. Had mine for over a year with no complaints. Good Luck.
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.
