Advice.. Integrated vs Seperates - Low Budget..

Here's the dilemna. I've got two different dealers I deal with primarily, I respect them both and they have very different sets of opinion - which is fine :) So I'm looking for a 3rd...4th.. etc sets of opinion.

I do have a Passive Pre-Amplifier. FT Audio's LW1S2 infact, and have been using it with my NAD C350 (now looking to sell it and move to a real poweramp).

However with my limited budget locally my choice for a poweramp is basically either the Rega Maia, or the Monarchy Audio SM-70. Both of which are hovering in the $800 CDN ($600ish USD) range.

So my one dealer is suggesting that I go for the Monarchy/Passive Pre-amp which does sound very good. The other one is suggesting that I give up on the whole idea of seperates and go to an integrated in the $1500 CDN range, which would be around $1150 USD.

I know that Integrateds have been getting better and better and that in the mid - high end it appears that there are integrateds that can match some seperates (Sim I-5, Plinus 9200, Vecteur etc). But for this price range - where I'm at wouldn't this very nice Passive Pre and match it with a good Power Amp best any similarily priced integrated?

As well can someone please correct me as to the benefits of seperates vs integrated? I had thought it had a lot to do with flexibility (ability to mix n match tube pre with ss amp for example) reduced crosstalk/rfi etc.

Thanks in advance,
