Hey Jughead, so you do have the Paraound 2100 and 2250 right now? And you're considering either the A21 or A23 with the P5?
I've got the P7, pretty close apparently to the P5, and the A21. My speakers are Paradigm Signature S6, 4 drivers including tweeter per speaker, and a sensitivity of 91 with 8 ohms rating. But they go down to 3.2 ohms at a lower frequency. Anyway, to get the volume I prefer, mostly under 80db, the A21 is just loafing along not anywhere near full power. So it depends on what volume levels you prefer and room size. Mine is a fairly big space in a basement that's pretty open, about 600 square feet.
Your speakers are rated at 90 db sens, with 6 ohms, so the load seems pretty comparable. Really, I'd think the A23 would suit you fine, it would drive your speakers to their fullest. I'd only consider the A21 if it's the end game amp for you, the last amp you'll ever buy. That's one reason why I bought it, that and it runs in Class A for the first 10 watts, said to be a nicer sound than the class AB of most amps.
It's not cheap though.
