The X600 is one of Pass Labs most highly regarded amplifiers, and it's actually still made. I believe they're up to version 8.

Unfortunately at some point they changed the cabinet from this beautiful three dimensional appearance with the big gorgeous round meter to a much more conservative look. I'm partial to these earlier versions.

The circuitry did not evolve much throughout these revisions, and the original X600's are still considered to be an absolutely killer amplifier. 

They're capable of driving just about any load down to 2 ohms, no matter how difficult. It will deliver its power with ease and finesse.

This particular example was well cared for by a single owner. It shows no signs of wear, use, or abuse.

There are no scratches or dinged corners or any discoloration. That's really something considering their heft. They present extremely *extremely* nice. 

This X600 set is also an excellent match to the Pass Labs X0.2 Dual Mono Line Stage Preamplifier, currently available as of this writing.

They will come to you in their original cartons and will ship via freight on a pallet for safe transport. Flat rate shipping to the Lower 48 US States is $600. And please contact us for a quote if you're on the East Coast or outside of the Lower 48 States.

Power cords and the original shipping boxes are included with your purchase.
