Thanks. Looked into the Purifi that was recommended. Didn't find any readily available kits for RCA inputs, but there is a lot of discussion on the DIY and HT forums about custom builds for these. Maybe there are some solutions that I haven't found yet...Most are very current hungry. This is easy for the better Class D amplifiers. Most will work out fine.

Gentle?Maggies are low sensitivity, so they want plenty of volts, too. Considering the A21 does 250 @ 8Ω & 400 @ 4Ω, Purifi seems questionable. Unless you're gentle on the volume knob, look at NC50x.
Best I've gathered from measurements, big Parasounds have been rated a bit conservatively, and the A21's 250/400W ratings are full-bandwidth at 0.2%. Not to go all @restorer-john here, but the Purifi's 1kHz distortion curves (ASR review) climb rapidly above 150/260W. Therefore, I conclude that the Purifi is not a good fit for someone who pushes an A21 near its limits. And I included the "unless" for the OP to consider his(?) particular needs.Gentle?
Good as the NC502MP is, the Purifi is a better sounding amp. 400watts V 500watts. I would choose the Purifi every time unless cost is an issue.
Sometimes the itch is not worth scratching.Keep the A21. End of story.
OTOH, if the Parasound is ~15yo, selling before it needs service might be a smart call.Sometimes the itch is not worth scratching.
Very good point.OTOH, if the Parasound is ~15yo, selling before it needs service might be a smart call.
Alan, please note that by "NC50x" I mean both NC500 and NC502MP. Do you consider NC500 a viable alternative for people who need more drive than Purifi can handle?
Keep the A21. End of story.
