SS Integrated Amp for Tannoy Turnberry GR Speakers

I plan to move from a PS Audio BHK pre amp and BHK250 power amp to a SS integrated amp - no tube amps.  I am also considering replacing my Tannoy DC8Ti speakers with Tannoy Turnberry GR speakers.  I'm making the move for two primary reasons, (1) I want to deal with a little less gear and (2) I'm looking for a warmer sounding system.

I really like my current setup and overall it sounds really good to me.  Sources connected to the BHK pre amp are (1) streaming: Innous Zenith MK2 to Matrix X SPDIF 2 to PS Audio DSD DAC and (2) vinyl: Technics 1200G/Ortofon Quintet Black to PS Audio Stellar phono pre amp.  I also have a Teac X-10R R2R with dbx 224 noise reduction unit that has been sitting idle for the past 6 or 7 years and I plan to change that.

I have a small dedicated, untreated listening area in my man cave.  My basement is walled off so that it forms an "L" shape from my sitting position.  The front wall is 11'-3" wide; the short side wall to my right is 15'-9" long; the long side wall to my left is 28' long; the back wall behind me is 60' long.  Behind my listening room area along the back wall is a pool table area, bar/HO train area, and home theater area.

My budget is no more than 7-8K new or used.  I plan to keep the PS Audio Stellar phono pre amp and DSD DAC.  At the moment I'm looking at a Luxman L509X used or L-507Z new or Accuphase E-280 new or E-380 used.  I hope to audition both brands in the coming months.  Unfortunately, none of the stores in the DC area carry Tannoy speakers so that's a problem. 

My plan is to order the Turnberry's from upscale audio first.  If I like them out of the box better than what I have I'll keep them and sell my DC8Ti's.  If not, I'll send them back.

I listen to mostly 60's, 70's, and 80's old school soul/R&B, contemporary jazz, soft rock, and a little blues - at low to moderate listening levels.

Thoughts, questions, and suggestions are welcomed.
