Accuphase A60/Accuphase A45

I just bought an Accuphase DP-77 SACD Player and a Accuphase Pure Class A A-45. They sound great. However, I plan to buy a pair of Sonus Faber Extremas. I loved the design and the sound from these speakers. They are old but their sound is so sweet and musical. My concern is Extremas are so picky about amps and components set-up, especially power of the amps. I notice that the A-45 amp, as a pure Class A amp, even though it is rated at 45W/channel, it is so powerful and can drive full-size speakers.

However, i am still concerned about its ability to drive speakers such as Extremas. Any comments? please share with me. Thanks

Khanh have you compared the A45 to the A60, and can you advise me on the speaker selection with your amplifier

Sorry. I have not had a chance to compare a45 vs a60 but I have had a chance to listen to a-60 at an Accuphase dealer. They sound similar, sweet and powerful. Very 'accuphase' sound.

I decided to buy a Thiel CS 7.2 instead of Extremas last year. To my surprise, A-45 could drive Thiel CS 7.2 (Flagship model) quite easily even though Thiel speakers are normally hungry for power. I guess that Class-A amps of high-quality like Accuphase's are usually underrated.

Any thoughts or experience?

I once had an A-50V (50 wpc of Class-A) which had absolutely no problem driving Avalon Eidolons and Eidolon Diamonds, both of which are difficult loads. Seemed much more powerful than the rating.

I own a Accuphase A45 for abount one and half year, driving Dynaudio Sapphire with ease. It is a very fine and dynamic enough,very clean yet musical amp. I don't feel any shortage of punch with this amp. I have yet to listen to A60 or A65.
I listen to Plinius SA103 driving Dynaudio contour S3.4 at dealer showroom, plinius sound more lively, smoother and concert hall effect whereas A45 sounds darker, very quiet background with the same power of bass production as SA103.
I have no problem in long hour listening with A45 but I suspect SA103 may have long hour listening fatigue. Any SA103 user please have your opinion. Thank you.
