Accuphase Vs Parasound

The Accuphase is engineered much better - discrete analog stages, fully balanced throughout, etc, etc.  Much better part components.  However, it is full Class A into 30 watts.

Parasound INT is a jack-of-all-trades integrated that has every single feature you could think (phono input, bass management crossover, DAC, etc.).  It is Class A/AB, with a Class A bias somewhere in the 5-8 watt range.  It probably has more power than the Accuphase, but lower sound quality preamp for sure.  Parasound is going to be warm sounding as well, so it's difficult to tell which would "sound better" or "have more resolution".  I would probably hedge my bets on the Accuphase, unless you did not want such a heavy weight into the Class A sound.

Accuphase is excellent - However you already have Yamaha so take a look at their A-S series integrated amplifiers,  excellent sounding machines.

Good Listening

Thanks so much for all your feedback. Yes from what I've been reading, Accuphase is a superb amp. And the one I'm considering E-560 is a pure class A amp rated at 30W. I've been toying around with an SPL meter app to check the loudness of my listening levels. Want to know if 30W amp is going to be sufficient. To my surprise, the loudest I normally listen to is about 80dB. Unless this app is not accurate. 

I borrowed a yamaha a-s2100 from the dealer for about a week. At that time my Adantes were still new so I wasn't really able to get a proper assessment as I was still unfamiliar with the sound.

Yamaha does make a very fine integrated amp in their A-S series as above.  Happy Listening!
