1 x 600 watt Class D:

2 x 300 watt version:

I don't know anything about the SQ reputation of the "Texas Instruments TAS5630 with PurePath™ HD enabled integrated feedback".
With the new Hypex type N amp getting all the attention, I'm thinking these amps might be a low-cost alternative for less than high-end installs.
 -no affiliation with PE or the amp maker (whoever that is)

Classdaudio.com also sells boards and kits based on the TI chips. A poster on another forum said Tom of CDA preferred the IR (CDA/SDS) amps to the TI in terms of SQ. Here's the the thread:
