Class D Audio CDA-250 125 WPC CLASS D AUDIO POWER AMPLIFIER

Lightly used dealer demo in pristine, as new condition.  1 year P&L factory warranty included.  125 watts / channel into 8 oms, and 250 wpc into 4 ohms.  Bridgeable into mono at 500 WPC! 
Superb sonics and lots of power on board with this overbuilt, form factor friendly Class D Audio CDA-250C amplifier.  Impeccable build quality, and solid construction throughout go with this amplifier's uncanny ability to present music in a completely natural, tonally correct, sweet, smooth, and powerful manner.  Soundstage is immense, vocals are rich, smooth, and "in the room" human / natural sounding.  MId-band and upper frequencies are detailed, airy, and organic.  
Black anodized, brushed aluminum face-plate, with sculpted edges and high-quality connector parts round out a robust and elegant enclosure.   
Class D Audio is a small California based direct sales company that is making a line of outstanding amplification components, using top-end parts and superbly built enclosures at high value price points. 
At 12" X 12" X 3.5", and 17 Pounds the CDA-250 provides big amp muscle and performance in a desktop or big-rig friendly package.   Sounds great with both solid state, or tube preamps.  
Here are a couple of consumer reviews from Class D's website:
I bought a pair of Totem Dreamcatcher speakers two weeks ago and the next day the right channel went out on my vintage Yamaha CR 1020 receiver. I found an excellent condition Adcom GTP 400 on an auction site and ordered a CDA 250C to pair with it. My source is my Mac Mini feeding an Arcam rDAC. I'm using the Totems as near field monitors in my home office. They're 4 ohm speakers and not particularly efficient. Some people may think 250 wpc is overkill in a 12x13 room, but I hate it when amps clip and this has plenty of headroom to prevent such behavior.
My amp arrived this afternoon and I've been listening to it for about six hours. Straight out of the box it beat my Yamaha (100 wpc into 4 ohms) as it should. The sound is clean and the amp has enough to power to get all the bass these little speakers can deliver, and they have a surprising amount of bottom end for such small boxes. The Yamaha sounded good, but the treble seemed a bit bright because the bass wasn't as good. I got the Yamaha repaired, and will keep it as a backup. This Class D Audio amp is a keeper.
Best power amp I've heard in 15 years of audiophile hobby. I purchased a complete class D audio power amp and I have to say it bettered a Rotel, Vincent TAC hybrids and SS T+A (German), Exposure (UK), Marantz, Primaluna by a noticeable gain in transparency, taught bass, and even warm.  Best audio purchase since my transformer-volume-control.
