Can anyone identify these speakers?

Those are the Tablettes, and the venue is DejaVu Audio in Northern Virginia.  The proprietor, Vu Huong, likes to put ultra high end amps on the Tablettes to demonstrate how important is top quality amplification—even a small, lower cost set of speakers can sound utterly amazing with such amplification.  The amps he uses for such demonstrations include the likes of the Synthesis amps shown in the picture or exotic rebuilds of Western Electric 124 amps.

@mofojo Thanks, I'm really new to speakers and these have been the best I've heard so far. Seems like you aren't too fond of the ProAc Tablettes, can I ask why and can you recommend any other bookshelf speakers that are better than these?

@larryi Vu was the one that let me hear these speakers, I was really really impressed by the way the sound filled up the huge room. Seems like amplification is really important with speakers then, I will have to do some research on the amp he had hooked on to it as well. Do you know exactly which model Synthesis amp that is on the floor?

Why aren't you asking Deja Vu  Audio these questions?

The amps are the NYC model (commemorating New York City).  You don’t ‘need” amps that good, but, you will not extract all that these or ANY speakers are capable of delivering without pretty good amps.  The point of this demonstration is: don’t think that it makes sense to buy the best speakers you can afford and slap any amp on them.
