If you're one of those people who's never satisfied, you're in the right place.  Pure class A tube power at 30 watts can be highly satisfying and rewarding.  Why in the world would you need 400!?  Read on my friend...

Headroom allows for amplifiers to run in their sweet spot with low distortion.  Its distortion that makes amps and sound in general seem loud.  Remove distortion and you have dynamic headroom while entering the realm of realism with sound reproduction.  This much tube driven power allows for precise control while revealing micro details in the music effortlessly. The Orthos' ability to deliver transparency will take your breath away.

Its interesting that the competitors to the Orthos XS are VTL's Siegfried ($65K), VAC 450's ($80K) and Audio Research Ref 750's ($85K).  These are a steal for the power and performance!

These amps are in excellent condition.  Both amps include a full set of matched tubes.
