Onix SP3: What speakers are you using?

I have heard the SP3 with Clements, Sololiquy 5.3, Aurum Cantus Lesiure 3's and belive it or not a pair of $5,000 Living Voices are doing full duty with the SP3. Not bad at all. Im not a huge fan of Living Voice speakers but it was a very good combination. Very musical and presents a really nice soundstage. Not the best sound I have heard but surely one I could easily live with.

Had mine hooked up to a pair of vintage large Advents, as neutral a speaker as you can find; very good combination. Now I have it hooked up to a pair of Onix ELT525 monitors and an Energy subwoofer. This little wonder did well with both sets of speakers.

As there is a pair of large Advents on the 'Gon right now, can you describe the sound, soundstage, imaging, etc. for me?
What size room? Stands? Anything else relevant...

BTW: I am using a pair or Onix Reference 1 Mk 2, a pair of Rega R3's and a pair of Rega R5's.
If you haven't heard these speakers you really, really should.
I know that everybody on Earth by now has heard the Onix references, but I find so little on the 'net about the Regas. They are quite simply superb speakers.

Rhanechak-

Here is a link to the Sterophile review of the large Avent loudspeakers:

As you can see from the review, they are detailed, neutral and accurate. I had the speakers in a very large room on 8" stands and they sounded great and could fill the room easily.

My Advents were re-foamed before I bought them, a necessity given how old they are. Make sure the ones for sale are have been or that you are capable of re-foaming them yourself for best results.

I am familiar with Onix line. I have a pair of mini-strata's in my home rig and love them. Have never heard the Regas. I have way too many speakers at the moment to audition a new set.

Good luck!
