Integrated amp for Sonus Faber olympica nova 1

There's always the Sonus Faber Musica!

How about the Musical Fidelity M6Si integrated amplifier?  It sounds great and your wife should like its simple classic design.  

“Internally, the M6si is configured as 2 independent mono-bloc power amps with a separate pre amp. It is, in fact, a pre amp with 2 monobloc power amps that just happen to share the same casework.  The M6si has 220wpc. It has very low distortion, outstanding noise ratio and extremely flat frequency response. Its inputs are phono (MM/MC), 4 line level, 1 balanced XLR and 1 USB ‘B’ up to 24bit 96kHz asynchronous.  The M6Si combination of high power, high current and extraordinary stability means that it can drive any loudspeaker with ease”.  

I own this amp and like it very much.

You might find the Circle Labs A200 interesting. Here's a thread on Audiogon where owners share their opinions.

Seems like she warmed up to the sound when you switched to the Pass. She’s an audiophile! You should explain that the amp is beautiful because of the sound quality it provides.  I’ve heard that the Pass/SF combo is a good one.

Why would the wife pick the amp out?  I have brought dozens of electronics and speakers through my living room over the past 35+ years in our current home.  My wife never, ever once complained, she couldn't care less.  When I got the Triton Refs, I kept telling my wife while I waited the 6 months, they were going to be big.  When I set them up, not a peep about the size.  I would never have to say anything to my wife, she knows it's important to me and that is ok with her.  I guess I am one of the lucky ones.  

If I were the OP I would talk to my wife and explain that the Pass amp is matched pretty good to his speakers or something.  Let her know it's important to him.  If he is a "yes dear" kind of guy he hasn't a chance, but if he questions, who knows?
