Best Tube Amp For Sonus Faber? Or Pass XA-100.5? $6-7,500 Budget, Purchasing Used.

As the title says, I have a pair of Sonus Faber Olympica III's that I am more than pleased with, for which I am trying to determine the best available amplifier, preferably tube. Of course, there are always budget limitations and my budget for this amp would be $6-7,500, and I would be buying used to maximize purchasing power.

Based on a lot of research, and quite a few auditions at brick and mortar stores, various home systems, Axpona, etc. I'm honestly not sure if there are any truly exceptional tube amplifiers available within that budget that meet my needs. These speakers need 100wpc tubed, or 200 wpc solid state, into 4 ohms to really open up and perform. 

If, in the end, there are no really great tubed options, I've always heard that the Pass Labs XA-100.5's were probably the optimal choice in solid state for former tube lovers. I would also appreciate any thoughts on that option from owners.

Nice! jmcgrogan2-

at its price-point, the ARC Ref5 pre-amp is best in class.

Happy Listening!

Thanks very much for all the input, guys. Like jmcgrogan2, George and kdude66 , I am more and more of the thinking that a solid state amp is probably the way to go with these speakers. I've just been a tube guy for so long. However, great performance is great performance, no matter how one gets it.

The 100.5's have been recommended previously by at least half a dozen audio people who I truly respect, including a couple major audio reviewers that I discussed it with at Axpona. Now the question is waiting for some to appear for sale. I have been on the waiting list at Reno HiFi  quite a while for a pair of 100.5's. Lets hope that Mark is able to come through with some sooner than later.

Mark at Reno is a great guy to work with. I bought my XA-100.5's from him.

I have noticed that Reno's used inventory has been "drying up" though.
I've been looking because I have thoughts of moving up to a XA-60.8/100.8.
Haven't seen much used stock in there though, mostly just demo's which are still quite pricey.

Keep your eye on HifiShark too!

I use the Merrill Audio Veritas mono block amps with my  Sonus Faber Olympica III's .The combo is just what the doctor ordered... Powerful,musical and a purity of sound that can leave other amps by the wayside. Highly recommended.

ARC Ref 150SE makes the most sense with the SF measurements.
