The Eastern Electric is a real winner! Very toneful and tuneful, inner details with excellent bass. Put the unit through its paces with a pair of Altec model 18 604-8H speakers. These speakers are merciless for the correct tonation, balance and details. No sibulance, but pure musical tones, depth and structure. The M520 is extremely well built, great output trannies, can use another preamp of choice. I liked the zero feeback mode, in pentode class A operation 24 watts per channel, will put many SET amps to shame. Extremely low noise, great PP dynamics and tone.
What is the best tube integrated amp?
I love tube amp since I started to get involved this hobby. I have also listened to many tube stereo amp, monoblocks and integrated (not too many?)amps. But right now I have tried to look for a tube SET or PP integrated amp for my office I still not find for my taste especially vocals, classicals and instrumentals. Therefore, I need some help from someone who has had more experience than me about the tube integrated amp for a small office. I also want to look a pair of monitors which are matched with. Thanks to everyone who anticipate in this thread.
