Best Class A amp with SLAM

Of course, the class A amp with the most slam is this one:

-but I assume that cost is playing a role here too :)

Hahahahaha.....funny guy Atmashere!!

After hearing a few Class A Amplifiers I finally settled for the Clayton M300 for SS Duties. Pass Labs and few others are at first have a wow factor but eventually you tend to grow out of them. With the Clayton it has that warmth and transparency which is I find pretty satisfying. Clayton now sell for 19000 Dollars a pair of M300 but you can get them cheaper.

Nice amps Atmasphere! I would be proud of these babies!

Atmasphere, I bet those would drive my OHMs nicely!

Any deep Black Friday discounts coming up?

Seriously, how practically does one keep all the tubes on a device like that functioning properly? I imagine a relatively small investment in a good tube tester would help.
