Is the move up to Parasound Halo A21 worth it?


Currently enjoying my B&W CM10s, Parasound A23 and P5. I really love the balanced, open sound that I'm getting from the current setup. However, there are a few areas where I'm seeking improvement. A wider soundstage and more engaging sound at lower than moderate volumes. And, a bit more bass, at any volume, won't hurt either.

I thought of moving up the Parasound chain to an A21, but I have no way of listening to an A21 prior to buying it. Has anyone else here moved from a 23 to 21? If so, did you think the move was worth the extra $$$$? Very interested in knowing what improvements people heard. And yes, I understand that room acoustics and treatments will give you a better bang for your buck. But, unfortunately, my setup is in the family room with very little flexibility. So it is what it is.

On an unrelated note, I was thinking of buying used (couple of current A21 listings here @ agon), but after you take into account shipping and paypal charges, the diminishing returns kick in. I'm struggling to see if net savings of around $500 (over a new one from audio advisor) is worth losing warranty, as Parasound warranty is not transferable. I'm sure these are highly sought after units and the premium is better than other comparative brands, but for me it's not worth the risk. So, I'm now thinking of getting a new one from audio advisor (no tax, no shipping charges) and have the peace of mind that comes with a full warranty.

Thanks, 213runnin .... can you provide some suggestions for speaker cables that go well with the A21? At least it'll give me an idea about what to expect.
Before I pull the plug on the A21, are there any other recommendations within the same price range that I should consider?
Odyssey Stratos with upgrades. I like the A23 for it's price, do not particularly care for the A21. 
Thanks, jl35. What exactly is it that you don't like about the A21? I'll look into Odyssey, perhaps a used one.

I also saw a Hegel 300 integrated on sale here at agon. Have always heard good things about it but not sure how it stacks up to a A21/P5 combo.
I found it kind of bland or flat. More that I didn't like it as opposed to disliked it. If you're looking at integrateds too there are very many possibilities...I've been very happy with recent Simaudio products...
