Good Speakers with Pass XA30.5 Power Amp?


I'm currently using a Pass XA30.5 power amp (with Pass XP-10 preamp) to drive a pair of PSB Synchrony One. Cabling is all Wireworld Equinox 7 and room is about 12'(W) x 24'(L) x 12'(H) with speakers firing down the long dimension - although I can only sit about 7' from the plane of the speakers. I find the sound somewhat laid-back, i.e., lacking in liveliness and I'm constantly fussing over the sound of the system. I listen at very moderate levels to a wide variety of music, but typically jazz (vocals), classical and choral music - with the occasional reggae and pop fare.

It's been suggested to me that the combination of the Pass XA30.5 and Synchrony One may not be a good match so I'm soliciting suggestions for speakers that should work better with the Pass amp - i.e., a more lively presentation. I'd prefer full-range speakers at least the equal of the Synchrony One in resolution and frequency extension. My budget is less than $4k used.

Having participated in your previous thread, I’d like to add some facts regarding the Synchrony One. It is a demanding load with an impedance magnitude which stays below 4 ohms throughout the midrange and drops below 3 ohms at several frequencies. Specs; 88dB sensitivity/4 ohms.This speaker performs well with high SS power/current, so I recommended a more efficient and neutral speaker for the Pass’s 30wpc/8 ohms.
I have a Pass Labs XA30.8 and its currently powering my Proac D-30Rs.
They are an easy load for that amp and match well together IMO.


Anyone try original Quads (57s) with the XA30.5? Apparently the XA30.8 is a great match for the Quads according to an online review.

I have a Pass XA 30.5 that I switch out time with a pair of VTL MB 125 tube amps and I love it with my Wilson Sophia 1s, really nice combo and our listening taste and music are similar.
