Best amp for Sonus Faber

It is easy to conclude that tubes are a lot of work. Before I retired, I never changed a tube, even though I had some components for six or seven years. Now that I am retired I listen to music a lot more. So, I just changed the tubes in my preamp and amp after four years. I have had no "interesting" experiences with tubes other than incredibly great, musical and natural sound quality. If you listen to a hour a day depending on the application it is likely they will last ten years, often small tubes, more. 

I have Accuphase T-101,C-200 & P300 driving KLH Nines. No one has not liked immensely the sound of the system. I do recommend any original, not counterfeit Accuphase products made in China. I was going to bring my T-101 to get repaired at JustAudio in Baltimore MD because the center tune meter didn't respond, wasn't able to get any stereo stations or have the stereo relay illuminate the front panel light. Tuning was extremely noisy as well. Totally unusable. Visually inspected circuit boards, checked a few caps and resistors to verify functionality and finally I cleaned the oxidation from 6 x 6 PIN header and receptacles on both boards and the tuner has been restored to it glory, listening to WQXR in NYC, the stereo separation and super quiet background is a JOY to listen too after having it lie dormant for 7 yrs. Saved a 6.5 hr trip to Baltimore and back. Very happy

By the way IMHO my KLH Model Nines are pretty flat across the board and no matter if I'm using my 90/wpc Futterman H3A or Accuphase P300 or McIntosh MC250, they all sound good. What matters as much as the room and quality of source material, is knowing the listeners specific hearing response curve by an audiologist and compensation for any loss especially in upper octave with a high quality 31band EQ. REW and associated Umik1/2 calibrated mike's make a fun tool in understanding how everything works together.

Rdiiorio I do have the modified KLH model 9 , they sound good with my plinius sa 100 class A amp. 

I have Sonus Faber Ill Creamonese Ex3me  and after trying many amps I  have found what works for me.  This is end game.   

Pass XA 160.8  I bought a used pair and cannot express how good they are.

Using Moon 891 as source and preamp, and DAC 

I went from Moon 860a V2    Is good but not as musical as the pass XA

the Pass XA 60.8 would most likely be fantastic .   Tube sound without the tubes.
