Bookshelves: Jamo C803, PSB GB1, or PSB Image B6

[jsr]

I'm considering picking up a pair of nice speakers for music only. I'm mainly looking at bookshelves as I figure I can get a "better" speaker with "better" parts for the money than an equivalent tower. Budget would be about $500 for the pair, but the lower the better. If anyone has any experience or insights with the following, please share. I will try to audition them as time permits (all except the discontinued one). I'm looking at B-stocks because, like bookshelves, I figure more for the money.

Jamo C803 - $400 - B-stock
PSB GB1 - $500 - New, but several years discontinued (no auditioning)
PSB Image B6 - $400 - B-stock

Or might consider the PSB Imagine B for $650 (B-stock) if it's that much better than the others, but that's stretching it a bit far on budget.

I've not heard any PSBs, but have heard a Jamo S426.

Thanks.
