Higher-End Class A/B vs. Class A Integrateds

I have the Luxman 595 Class A amp. I also have Yamaha AS-3200 Class A/B with the Yamaha rn-2000a as pre amp. 

The sound traits (to me):

1) Luxman 595 - Has a powerful meaty sound. Sounds a bit stuffy. Not very holographic. Sounds excellent for Jazz and also colombian music, though. 

2) Yamaha set up - sounds open, not stuffy. Good at being holographic.  I like the sound stage more than the Luxman. Sometimes can be a little to strong in the highs. It's bass is diff. from the Luxman. More tight/refined but less full compared to the luxman. The luxman bass can make the Bookshelves sound like towers. But I still like the Yamaha's bass a lot. 

Overall, I listen to the Yamaha setup 90% of the time. I use the Luxman for just jazz and Colombian music for the remaining 10%. 

I feel like the heat generated on idle is close to the same between the Luxman and the Yamaha as-3200. With the Luxman being maybe a tad bit hotter but not much. 

As others have said, try the different topologies and settle on what suits you. It’s really the only path to satisfaction. I happen to consistently prefer class A, but I would never say it’s categorically better. 

I just put my Black Ice Audio 3502P tube amp in with EL34 tubes.  After listening with the McCormack DNA 0.5 solid state amp all summer, it sounded warmer but sluggish(?) especially with rock music.  Small Jazz ensembles, acoustic music and vocals sound fine.  

I'm going to try the Gold Lion KT88's in to see if they make much of a difference.  

I'm trying to determine if I need a higher powered integrated than most Class A amps provide.

@dman777 - A lot of what you describe is what I hear with my 507ux.  I wonder how much of the character of our integrateds is in the preamp and not the amp section instead?

Also, speaking of bass extension, I highly recommend the Mogami quad speaker cables with the Luxmans.

@erik_squires for the Yamahas, the 2000 greatly influences the as 3200. With the AS-3200 by itself I do not like it. It has to be with the 2000. They go really good together. 

I have not messed with any preamps for the Luxman. I figure for the price, if it's not good enough standalone then I don't want it. I am on the fence on selling my Luxman 595. I will eventually buy the MacIntosh 12000. I might sell it down the road if I find I do not use the Luxman enough. It's hard to give it up... it does sound better than other amps for Jazz music.
