pre-amp and amp for 1K

I think that in that price range you may be better off with a good used integrated amp with a HT bypass. I just recently posted a thread asking for the best used integrated for my B&W cdm1nt's (88db efficient compared with your Soliloquy's 90db rating) Most of the people seemed to be leaning towards the Classe, Electrocompaniet, Plinius (a little pricier), Krell 300i and I think a few others. I chickened out and ended up with a Bryston because I like the 20 year transferrable warranty and the fact that Bryston has a great reputation and is used in alot of major studios around the world. I am very happy with the Bryston B-60. For $825 delivered with 18 years warranty left to me it is a no brainer. It sounds better (to me) than the Denon avr5800 that I had originally listened to the CDMnt 7's with. You may also want to let people here know what kinds of music you listen to as some of the integrateds suggested to me seemed to be more commonly suggested to others for classical and jazz and others seemed to be recommended more for pop & rock. Anyhow, I'm just a beginner here but that's my 2 cents.
Happy listening

Integration is fairly simple, some pre/int's have processors loops that make it a snap. If it doesn't have this loop, you can still do it with any unused output from the pre/int. In this case you have to fiddle with the volume a bit.

This assumes that your receiver has pre-outs.

Interesting situation: I would definitely separate HT system from 2ch stereo:

Use for 2ch stereo your main Soliloquy 5.3.

Get for HT some cheap and descent monitors.

Try to mate used passive McCormack line drive($325) with used Bryston 3b-st($900).

If you cannot separate HT from music it'll still work with two sets of speaker wires running from your HT receiver and from your power amp. Make sure that receiver and amps are not on both at the same time.
