Integrated amp for Thiel 3.7's


I am sort off picking up where Thieliste, Jafant and others left off in the discussion thread about what electronics to use drive the Thiels.  I was, and I suppose still am looking for a preamp to drive my pass labs 60.5 mono's, but in reading some of the posts I have also started considering simplifying my system and just going for a high end integrated.  Part of the reason I am thinking about going in this new direction is that we may be moving- and this might be the right time to scale down.

I am not sure yet, but I have started thinking about it. 
For preamplifiers I keep on toying with the idea of a PS audio BHK, Pass labs xp12, Simaudio 740p, or an Aesthetix Calypso Eclipse.  One of these would replace my Prima Luna Dialogue Premium- as I have mentioned before I think I can probably get better detail, definition, and depth a preamp with a higher quality volume control (vs the Prima Luna blue velvet).

But maybe a high end integrated might actually do the trick as well- I cannot afford one of the new Uber integrateds but maybe some high quality used ones might work.  I am budgeting under usd10k.  By selling my other equipment I should be able to get to my budget with a relatively small additional investment (usd1-3k ?).

So I have been looking at Luxman 509x, Nelson Pass Int 250, Vitus RI-100 or RI-101....Diablo 300 would be out of my reach even used but maybe the 120, and maybe an ASR (the exclusive 2 would be so many boxes that it would defeat the whole purpose of consolidating the system- so maybe the 1?).  On these last 2 I really have no idea about how much one gives up going with the lower models.

Ultimately my hope is that the list above will still get me further than where I am with my current set up.

Anyway, would be very interested in your thoughts as I look at this new angle for my system.

Hmm thanks for that- definitely interesting.

Btw, anybody have thoughts on the Nelson integrated (250)...reviews are good and I obviously have some familiarity with the Pass sound that works well with the Thiels.
I obviously have to wonder how the INT250 would compare to mono 60.5's with the Prima Luna preamp....I would suspect that for the INT250 to be an upgrade the preamp section would be key.

Generally push/pull complimentary Mosfets aren’t too good at doubling wattage and supplying current down into that broad band of 2ohms, I stick with and look for BJT (bi-polar) amps. Maybe the Coda above?

Thanks unsound.....but the price!
Can't really go there- even the progression clocks in at $18k.
^Yes, “the price” indeed! 
i think the value choice is to go used Krell separates.
