Class A Solid State Sound

A pill! I love that old expression, my mom used it a lot.

Why hasn't anybody spoken about Boulder amps. They are class A with sliding bias which for some unknown psychological reason I am uncomfortable with. Of course 250 large for a set of boat anchors is a bit steep even if your floor can support them. Next model down the 2150 at 100K is a direct competitor to the Pass Xs 300. Anybody ever hear a Boulder amp? Why would one buy it over the Pass?. 

Oh and George, a 200 watt class A amplifier conceptualized by a Danish
Graphic Arts guy and designed by teams of worker bees resulting in......?
I would prefer the work a dedicated electronics engineer who puts his reputation on the line with each amp preferably American. I would never even look at a Gryphon. Too much invested in flash resulting in rather silly looking stuff. Sound and durability are all I am interested in spending money on.  

Concerning Boulder, I would not say that it's a direct competitor to  Pass Labs.  I heard Boulder at RMAF and it is a pretty neutral amp with only a touch of that bipolar Class A lush/liquidy effect.  The Pass Labs is a FET "warm and fuzzy" type of sound, but with high resolution that is very controlled.

Oh, mijostyn, the Gryphon gear is durable and engineered to high standards. I expect to be running my class A amp for decades. It sounds great, too. 

The Gryphon Colosseum is one of the most beautiful amps I've ever seen and it does not take up a lot of floor space because it is laid out vertically. Believe it or not, the savings in floor space is what sold my wife on the unit. I live in a small apartment and don't have the room for the massive amps from Boulder. Plus, Boulder's prices are insane, as you pointed out. 

George, before the Gryphon I was running James Bongiorno's statement Class A amp from the 1970s, the Sumo Gold. I had it completely rebuilt. It was a 125w Class A amp and gave me eight years of trouble free service. The Gryphon sounds a lot better, as it should, with improvements in various technologies over that time. I sold the Gold for $1k to someone who was glad to get it. 
I've just never liked the sound of MOSFET amps. To each his own.
