Integrated Amp for Monitor Audio RS6

Ok, I've narrowed down my selection to:

NAD M3
ARCAM A32
Krell 400xi
Primare I30

Has anyone had experience with any of these combinations? I'm also open to other suggestions.

Thanks

I forgot to mention I am also going to use this amp as a HT pass-through. I have an older 5.1 receiver that I may use on the rare occasions that I watch movies.

Don't forget to include the Cambridge 840A.

I have read some places that the 840A could sound a little harsh. Then again it wouldn't make sense why I have the Krell on there.

I am basically looking for a warm sounding amp that has pretty good extension and definition at lower frequencies. I'm afraid that pairing a bright sounding amp with these speakers may not sound that good. I recently had an Arcam AVR280 receiver that sounded quite good with these. I wanted to take a step up in 2 channel so I sold the receiver. I know I like the Arcam sound, but is there anything else out there?

I'm looking to spend around $1500 used on this (give or take $500)

fyi: I am going to connect this system with a slim devices Transporter for most of my music listening.

Ok,

I went and heard the 840a yesterday and I was less than impressed. The highs were harsh to my ears and I felt the sound was somewhat unengaging.

I've been looking around and am wondering if some ss integrateds with lower power will give me nice tight and controlled bass.

Bryston B60

Primare I21
MF A3.5

Any thoughts?

Primare builds some fantastic gear that doesn't get a whole lot of press. I'm an owner of their CD21, which is a fantastic sounding and very well built cd player. I had the chance to listen to a CD21 paired up with an I21 hooked up to Vienna Acoustic Mozart Grands and I thought the system sounded stunning. I would try to listen to a Primare I21 because I've found their gear to be smooth in presentation.
