Please help me find a power amp

I have a Music First Audio classic Mk II passive Preamp. I had initially planned to pair it with active speakers but after numerous trials with the likes of Quad, ADAM, Genelec and ATC speakers I have come to the conclusion active probably isn't for me. I like my music with a dollop of warmth which seems to come more readily from passve speakers.

So I have just been through months of speaker trials and I am down to a short list which includes the Harbeth SHL-5 and the Sonus Faber Cremona M Auditor. Both of which I have listened to several times. I like both the Harbeth and the SF but I slightly prefer the SF (it has a certain je ne sais quoi although the Harbeth also has it's charms). I am restricted to standmounts due to room size constraints.

I have used my Dussun V8i integrated for the comparisons but prefered both speakers with slightly warmer amps (Copland/Manley) which will be out of my budget for a while (budget probably around 2k GBP). Current source is a Caiyin CD player and a Squeezebox Touch into Xindak DAC (which will all be upgraded as funds permit).

Can anyone suggest some power amps (or monoblocks) I should trial? Balanced inputs would be a bonus.

I can get very good prices on the Usher R-1.5, MBL 8006A and TRIODE TRX-P6L Reference (but wouldn't be able to listen) if anyone has any experience with these amps.

My music preferences are pretty wide - so I am looking for something versatile. Solid state preferred (as I usually forget to turn things off when I go out/to bed etc).

Cheers
