Help - Opinions - Amp for Sonas Faber Olympica III Speakers

 The Olympica III are very nice speakers. At 90db they don't really need a ton of power.  I know you have a very large room. For solid state my choice would be an amp from Pass Labs. Maybe something like the X150.8

I have the Elipsa SE and drive them with an Audio Research Ref 110 tube amp. I have heard mine driven by the XA60.8 mono blocks and it was an excellent pairing. They really benefit from high quality power.

If you want to go with NAD, I'd seriously consider the purifi equipped model instead (C something).Other low-cost alternatives are ATC's amps, and mid-range musical fidelity models.
Of course, the Pass labs mentioned above are excellent IMO (but more expensive)

I went with a Classe Sigma Amp2.Class D with 200W 8 ohms, 400W 4 ohms.
Got it for $1553.00 shipped. I was told Classe was bought out and the new company was selling off old stock.
For that price worth a try.
Thanks for the input.

@greywolf You have really, really good speakers. I'm sure the amp you bought will be quite good, but I feel you owe it to yourself to try something that will be on par, price-wise and sonically, with your speakers. I don't know your budget but I have found that class A amps (at least the first 15-30 watts) from Luxman, Coda, Pass Labs, Accuphase, etc. are a great match for SF speakers and compliment them quite well.

Update on what I ended up with for my Sonas Faber Olympica III speakers.

NAD C 658 Preamp with HDMI module. 
Classe Amp 2 amp.
Velodyne HGS 10 sub. Had this unit.
LG 65 inch TV. Had this.
Logitech 665 Remote.
Arcam DVD/CD.
Raven Audio XLR's.
Audio Quest Cinnamon 48 HDMI cables.
Audio Quest Greyhound Sub cable.
Mogami speaker wire. 
Speakers are Bi-Amped. Classe amp made for this.

Pleased with this set up.
The GUI on the NAD C 658 is not easy to use IMO. Hard to navigate and understand what changes are being made on some settings.
The 665 remote works great and is easy to program using a computer.
The Raven Audio cables are a quality product IMO.
Mogami speaker wire I have used in the past.

Someday may change out the amp. OR? You know the drill.
