I purchased the PS Audio GCA-250 for 900.00 Used off craigslist. I needed an amp that could control my woofers on my Revel Salon 1. I was using a Pass Labs XA30.5 to run the Salons for 30 watts per channel it did an Excellent job. But when I wanted to go Loud the 30.5 could not keep up. The GCA-250 at 30 watts of power felt like it had 3x the bass as the Pass Lab Amp. The Bass on the GCA-250 was Solid Powerful but also Faster with better attack & decay. My Revels at the lower Frequency's is 3.3 OHMS. so the PS Audio amp should put out about 700 watts per channel. it Rocks. the Mid on the GCA-250 is not as lush as the Pass Labs but the PS Audio was more transparent with a deeper & Wider Soundstage. I like the PS Audio overall better than the pass labs. The PS Audio Amp runs Really Cool Not like Class A Amps or even Class A/B Amps. I Owned A PS Audio HCA-2 Amp and it was great, but the GCA-250 Blows it away it is not even in the same Class.
I Defiantly Recommend the GCA-250 for any one. Even at low volume it sounds Fantastic.

Like its big brother, the GCA-500, the 250 is rock solid, both in sound and build quality. Mated with the PS Audio
PCA-2 with the HCPS, the sound is sublime, effortless, Dynamic, explosive, and yet the most barely audible sounds are reproduced with ALL of the clarity of a "Live" Performance. Using high quality power cables, and
interconnects, are crucial to appreciate the PS Audio's Full potential.

I have many 200 watt amplifiers, Aragon 8008ST, among them, but none of the other amplifiers can convey
the utter clarity, and unbelievable power that seems unlimited with my 95db. speakers.
The "jump factor" that is, the speakers ability to "Launch" the sounds, with laser like accuracy, to the listener.
Is simply put...Outstanding!
In a car analogy, the Aragon would be a Camaro, and the GCA-250 would be a KOENIGSEGG CCX Super Car.
PS Audio is seriously under rated in High End Audio
Dead quiet, no hum or hiss.

I have listened to many other products, PS Audio works great for me.
