Emotiva XPR questions

[biotechsmc]

I'm on the fence about purchasing a XPR-2 (or 2 XPR-1), I currently have a XPA-3 in my bedroom set up (so I'm familiar with emotiva), and a parasound halo A21 and A51 in my living room set up. My questions are would the XPR-2 be an up grade sound wise over the A21 in driving my focal 1038 BeII. Also, those of you with 2 or more XPRs are they all running on their own dedicated 20amp circuits? or can I run 2 XPR-1 on a single 20amp circuit if I get 2 of them instead?


Thanks for any responses in advance.
