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.

Opinions please.

UPDATE
Went with a Parasound Halo JC5. Will report back after later. 

Yikes.
I would have gone Simaudio the III matched perfect with my 340ix.

Parasound makes good amps.
    Waiting for your review...
  

I'm sure Moon is good stuff and I'm glad you're happy with it .....but,
The 340 is less powerful, doesn't tell you if it will handle low impedance loads. 
Spec wise the Halo JC5 is better IMO. 

My local shop had had the Olympica 3 on a Parasound, Classe and McIntosh. They all sounded good. I don’t think it is a picky speaker. 
I like the Classe the best by a bit but that setup (latest abs greatest) was twice the price of the speakers. 

The Parasound Halo JC5 tamed some of the brightness that I had with the Classe Sigma 2 amp.
Definitely an all around improvement. More musical, better bass control but it did loose some bass punch.

Then I switched XLR interconnects to Mogami's made by Jerry of 10 Audio. This was a big improvement. Detail, clarity and bass improved. I highly recommend them for $109 for 1 meter pair. 

To me the amp and the Mogami XLR's ended my search for improvement. My system sounds great to me. 

FYI
I was using XLR's by Raven Audio. Jerry cables are listed here on Audiogon.

My system:
NAD C 658 Preamp with HDMI module.
Parasound Halo JC5.
Audioquest NRG-Z2 Ac power cords for pre and amp.
Velodyne HGS 10 sub.
LG 65 inch TV.
Logitech 665 Remote.
Arcam DVD/CD.
Mogami XLR's By Jerry at 10 Audio.
Audioquest Cinnamon 48 HDMI cables.
Audioquest Greyhound Sub cable.
Mogami speaker wire 2921.
Speakers are Bi-wired.
Sonus Faber Olympica III.

Sorry to say got the audio bug again. Looking at amps again. This time Coda Continuum TS.

Thoughts on the difference compared to my Parasound Halo JC5.  

Thanks

I owned the Parasound JC5 . I was powering Kef R900s 

Preamp T1 tube with nos tubes . The JC5 was superior to A21 , Pass 150,Premaluna 300hp, Mcintosh 302. Then I had purchased a Coda continuum TS to compare against the JC5 . The outcome of the comparison between the two was that the Coda continuum TS was a far better controlled and musical presentation in all areas. Ten year warranty. If you call the company you will likely speak to the owner and designer directly. 

I'm having very good results with ARC REF75SE.  Had 2 McIntosh solid state amps,  Pass Labs X150.8 and the REF75SE sounds the best.  

The ARC REF75SE sounds like an awesome choice.  I’d also look at the newer GaN amps from Atma-Sphere and AGD.  Or, buy a used McCormack DNA-1 and have SMcAudio do their full mods on it.  All are awesome options.  

The proverbial quest for nirvana. My opinion is you get bored with your system.

Waiting for a NAD M12 to ship.

After lots of looking at amps I decided to go this route. The only amp I wanted was a Coda Continuum No 8 with meters. 

I figured the pre amp was the weak link in my system and this was less money.
