What amps should I audition?


I’m thinking ahead (crazy I know)

I want to purchase a high end amplifier next year, maybe an integrated or just a power amp.

I would be looking to spend around 15k max on an integrated, and 8-10k on a power amp separate (funds to acquire a preamp will be got at a later date next year)

What brands and what model from each brand should I try to get a home audition for? 

I should note I would probably be buying new as I can’t imagine I will be able to get a home audition with used gear. I’m open to buying used, but I’d have to get an audition in a system like mine, or actually in my system... I don’t really want to buy anything without auditioning first. On a related note, what is the easiest or best way to get a dealer relationship started, one where he would let me home audition? I’m even willing to pay 100% deposit if it means I can return it no questions ask after the audition period, but the dealers I’ve asked to do this with so far have refused. I always see people on this forum saying they manage to do that. I’m a bit at a loss how they manage to pull that off.

Anyway some more ideas: Bryston amps and Nagra Classic pre? This was the only setup I’ve heard on my speakers and it was quite magical. I really like the Nagra, and the Bryston combo. Used, it could be got within my budget. New.. not so much. I could swap out the Brystons with the matching Nagra amp, maybe. Or even just go for the Nagra Classic Integrated. All within my budget (if used) and with my speakers 96db sensitivity I should be good to go with the Nagra 100wpc rating.

other ideas: mcintosh mc462 or mc275 mk vi. 
Pass Labs XA30.8 or XA60.8 or XA100.8
Acxuphase e-470
Luxman 509X 

Actually that’s all I’ve really come up with so far. I am open to hearing any thoughts, concerns or ideas you may have. I do believe all the above mentioned amps will better my Kinki EX-M1. 

Cabling will be upgraded to Audience before any of this by the way.

I would certainly include the Ayre AX-5 at that price point. I also like the sound of ARC gear but not sure about their integrated amp.
It bogles my mind when amps reach $20k putting out mere 300 watts @ 4 Ohm or sometimes even less. I am beginning to wonder if high end amps are like the magical cables that cost multiple $k.

What is the engineering innovation does a $20k amp demand?. If amp can put out 10,000 watts for $20k I understand, someone wants to go deaf after spending lot of money, or likes melting the speaker drivers for fun. Even $10k for an amp putting out less than 300 watts at @ 4 Ohm just does not make sense to me.

I guess I will never know unless I win a lottery.
D2girls.....check out the Raven Audio website.  Then call Dave Thomson, who is the owner.  Listen to his story.  I did.  I purchased the Raven Integrated Reflection MK2 tube amp.  Everyday when I listen to music I just smile.  
If we are just throwing ideas hoping one will stick... I wish I had the chance to try the Carver Crimson 350 Raven monoblocks. They are the only amps I would like to try besides just buying a Bryston Cubed something. Pair of 7B3s or a 14B3
