I own two tube amps - the Mcintosh 2102 which sells for 6k - 100 wpc and an EAR 534 which sells for 3800 new. The EAR is 50 wpc and has balanced and rca ins also has adjustable gain for each channel and can be set to mono. It looks great and is virtually maintenance free in tube adjustment. It sounds great ! Clean and powerful and works well with both types of preamps. The 2102 is warmer sounding - probably not as good in the highs but has more guts in the midbass and bass area.
