Should I buy PSB Image T6's for $800?

good speaker--no real flaws. quite efficient, so your nova should drive 'em fine, and i'd expect it'll be a definite upgrade for you. msrp is $1199; i see 'em advertised new for $999, so $800 used registers as neither a great bargain nor a terrible deal. at around the same range you might also consider energy veritas or revel f12, both also very good.

Someone else told me I should be looking at speakers with 98db efficiency and the Nova wouldnt be good enough. Does that make any sense?

Did you like the EPOS sound? I never cared much for the ELS3 (sounded boxy to me), but the EPOS M12i for $720 (HCM Audio) and EPOS' EPIC series are worth checking out.

The PSB will sound different than the EPOS, not better or worse, but different.

When Upscale Audio was first selling the Peachtree, they were pairing it with ERA speakers.

I have a pair of T65 for sale for $600 here on audiogon. very similar speaker. $800 seems a little high for used speakers
