review of Eastern Electric M520

I am very surprised not to see a review on this amplifier on Audiogon.
The model I purchased about 4 years ago was a special one with upgraded
coupling caps with Mundorf Supremes with the work done by Eastern Electric.
I have had many amplifiers and integrated over the years including very expensive ones by Jeff Rowland, Cary, Arcam, Mesa, VTL, VAC and this is my favorite. I have always preferred tubes overall and I believe that with the upgraded caps and some tube rolling that this is one of the best integrated
amps. anywhere near their price. The construction is excellent, reliability has been perfect, and the sheer beauty of the amp is very impressive. With the variable outputs between ultralinear/triode, variable feedback, and outputs this is a very tunable amplifier. I used fairly efficient speakers and the 24 watts/channel was very ample. Overall, highly recommended integrated with the upgraded caps. Call Eastern Electric for other mods available.

EE Minimax integrated on my short list for an inexpensive tube integrated to start a third system.    Also Sophia Baby, GLow Amp One, Jolida fx10.

Scott_w,

It’s doesn’t run too warm considering it’s got 5 tubes per channel. My listening position is 6 feet away from where I keep the amp and I haven’t noticed it heating the room or anything, but my listening room is in the attic and is fairly cool in the winter months. The transformer module does get a little warmer than usual because it is closely framed on both sides by the tubes. But all in all, it seems to run only marginally warmer than most of the other tube amps I’ve had (due to the transformer module's proximity to all of the tubes) and I’ve never had a tube amp that has run really hot. It will need adequate ventilation though, a good amount of clearance above and around it, for stable operation.
