Tube pre/power combo for Rockport Aviors


I have a pair of Rockport Aviors on order that should arrive sometime in Jan. The Conrad Johnson CT 5 pre and CJ LP 70S power (70 wpc) that I have at present may not have enough juice to do justice to the Aviors. Given the limited availability of brands/dealers in my part of the world,I have shortlisted 3 pre/power combos :
1. Conrad Johnson GAT and ARTsa(140 wpc)
2.ARC 5SE and Ref 150 or Ref 250 monos
3. VTL 7.5 mk 3 pre and 450 MB series3
The Aviors will replace a pair of Quad 2905s that I have enjoyed for 6+ years. My musical tastes extend to the whole spectrum from large orchestral works, chamber music, rock, blues, Indian music but strictly no Rap or Country. The preferred source is vinyl.
Ideally I would love to stay with the CJ line as I like the sonics though I suspect this may not be possible.I am not looking for recommendations per se but to those Agoners who have experience of any of these brands either through ownership or extensive listening etc. I have been fortunate to be in contact with some knowledgeable Agoners .
Many thanks and festive cheer

I am a bit intrigued by your statement that the Nagras 330b and VPAs could successfully drive the Aviors. The Nagras output 20wpc and 50 wpc respectively. Conventional wisdom has it that you need at least 150 wpc to drive the 89db efficient Aviors. This opens up a lot of possibilities. My CJ LP 70S with KT 88S produces 70 wpc. I plan to swap the KT 88s for KT 120s. If i am not mistaken this should output 80 wpc or there abouts. This may be more than adequate !
Jfrech,

You have convinced me to listen to the Avior's...if they are "Significantly" better than the Sasha's I'm going to sell them and get the Avior's.
You should really contact Andy Payor at Rockport to see what he recommends both for power requirements and what he likes with the Aviors. Personally I wouldn't do anything until I heard them with my CJ gear and then go from there, which is probably what you're doing. If you like the CJ sound it's a little hard to think you'll like ARC or VTL, which in my experience are not as warm or romantic sounding as CJ gear. But then again who knows? I really liked the VAC idea mentioned above -- perhaps a nice middle ground between CJ and the others you mentioned. You probably know Andy uses Gryphon solid state Class A amps pretty extensively to voice his speakers (I think they may be his favorite amps), but I'm sure he must use some tube amps as well so would be interesting to see what those are just for reference. I heard the Altairs with some big Boulder Class A amps and the sound was pretty damn nice.

Anyway, fwiw and best of luck with your high-quality problem -- and congrats on a great pair of speakers.
They have gotten great reviews when shown with the BAT REX pre and amps. Heard them with BAT SS amp at RMAF and sound was also good there.
I know at one point Andy had C-J amps in house, the Premier 12's I believe. This is going back some time, but he may still have them.
