Best Class A amp with SLAM

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.

Mapman...from the website product page:

"We included a very easy to use built-in tube tester (which can be used at any time the amp is on), allowing one to test the output tubes 'on-the-fly' in a matter of seconds. Bias and DC offset functions are automated, using an Atma-Sphere-patented method, with meters to monitor the tubes, output power, line voltage and other features."

Tube tester included...nice!

Auto-bias...that should help a lot.

I recall VAC features that on some of their best amps and touts how hard it is to pull off properly.

Now I just need the black Friday sale.....

Since we're talking CLass A here, I won't worry about the power bills, that's probably a given for any Class A amp that can realistically lay claim to having the best slam.

The BEST anything never comes cheap.

Chocolate maybe. Having tried many, Hersheys may still be the best.

Nice features on that amp.
