I find myself not using this amp very much lately and so I thought I'd pass it along to another person who can love and cherish it. I find myself using my "control system" 99% of the time lately as I am in "design mode" working on some large OEM cable projects, and, unfortunately the M520 just doesn't fit in that system due to the way the system is configured. And, I will be in "design mode" for at least 12-15 more months as I am working on some large and complex projects.
This is a jewel of an amplifier, just a sweet sounding design. It is always unfailingly musical. And, if one wanted a different sound, a bit of tube rolling (with some of the other plethora of tubes I will send with the amp), and viola', you have a different amp.
I would keep it, but I haven't even turned it on in at least two months (this is my fourth system, not counting headphone setups, ...), so, it's time to let her go.
FWIW--It is the amp used here to test the Shuguang treasure tubes I wrote about here Treasure tubes NOT included):
http://www.audiocircle.com/index.php?topic=64336.0In any event, I got the amp direct from Bill at Morningstar Audio, it was a demo, and it works great.
The bad:
One of the stainless uprights is loose (VERY common on these amps due to shipping)
The volume control knob is a little bit canted to one side (I think from shipping--I can probably loosen it and fix it, but, hey, full disclosure)
I'm sure there are a few small scratches here and there on the unit and remote
The good:
Works great
Sounds great
Looks great
Feels great
Tastes great
Has remote
Has original box
Has original manual
And, now, for the best part. Comes with all of these cryo'd tubes:
1--matched quad cryo treated Genalex KT77's (250-300 hours...maybe)
2--matched cryo'd Mullard f32 GZ34/5AR4's (marked Minwatt) (1000 hours--will last forever)
