Integrated Amplifier for the PSB Synchrony One B (bookshelf)


Besides the NAD which Integrated Amplifier would sound good (better, more open and detailed) with the PSB Synchrony One B bookshelf speakers.
Also, which stands height I should go with since the mid/bass is on the top.
I have Sound Anchor stands (25") and in my sitting position my ears are in the level with the mid/bass cones
so 26" or 27" would make sense but I am just concern about the bass quality if I place the speakers higher.
Thank you in advance on your opinions.

Belles Aria is a fantastic integrated . Better than you might think is Yamaha
801, not much more money than NAD , sounds better and is FAR more reliable .
parasound halo integrated.  just the right amount of smoothness to match with the PSB's occasionally bright nature.  
follow PSB's recommendation for speaker positioning and stand height.

Since you mentioned Belles Aria.
It is very strange from the manufacturer to not to publish specifications, only the power.
