Luxman 509X, 590AXII, or Gryphon Diablo 300 for B&W 802d3

I own the B&W 803 D3. Before they arrived, I owned the Luxman  L-509X. Something was missing big time compared to what I had heard these speakers many times at at least three dealers and a friend. So I switched to another integrated amp, my current T+A PA 3100 HV. Everything came back to life the moment I switched it on. Couldn’t be happier.

The Pass equipment is truly wonderful I'm using a 250.8 with magnepan 3.7i never a problem and rarely leaves class A. Reno HiFi will let you demo in home. There's also the used option which I took based on reviews

I had the 802D3 for a few years in my system and had a few different high end amp. My feeling is that the highs and mids will be wonderful with any of the amps you mention, but bass will be a challenge in any reasonably large room. The bass will be tight (probably more with the Gryphon) but it will never have that huge impact. If your a bass person, like myself, you might need to consider a pair of subs.

T+A Integrated’s are pretty awesome, ultra detailed and plenty of grunt in lower octaves. I used to own B&W 800D2’s and you can’t fully appreciate B&W’s (especially the 800 or 802’s) until you feed them with an amp that’s stable down to 2ohms load.
