Hi Jay, thanks for the feedback. Indeed T+A is extremely smooth, neutral and balanced! I liked the amp a lot.
I just came back from the audition (Diablo 300 and Essence). The Diablo 300, like many have already said the 'authority' is def. one of the best ways to describe the characteristic of amp and it's warmer (Class A for first 10W) than T+A. However, the Diablo 300 can be a bit harsh for the treble and it wasn't able to tame the diamond tweeter in contrast to T+A. The room at the dealer's place is ideal so I don't think it's the problem of the interface with the room.
In summary it's really down to personal preferences, either Diablo 300 or T+A PA 3100 HV. Personally I would choose T+A PA 3100 HV over Diablo 300 to pair with B&W 8 series including an important factor - the 'look' (like George said Wife Acceptance Factor).
I've put a deposit on the Essence power amp. The dealer unboxed a brand new power amp for me to audition, paired with Linn streaming DAC. Without burn-in and warming up, the Essence is just on another level...it is way better than Diablo 300 and T+A PA 3100 HV in every single aspect I can think of and it was able to drive the B&W 802d3 easily (I cranked up the volume on purpose to test how the amp can drive very dynamic classical music).
