integrated help please

I'd go with an integrated and outboard DAC, but that's just me. Good amplification typically outlasts sources (except turntables IMO).

If I needed an integrated with built in DAC, I'd look at the Bryston B100 and Naim SuperNait. I think the new SuperUniti (or something like that) also has a DAC in it. However, those are my presentation preferences. No idea what sonic presentation tickles your fancy. While the Peachtree stuff sounds pleasant, I've never had any desire to live with it. I haven't heard their new high end stuff though.

Nad M2 is worth adding to your shortlist

In your budget I would be curious to try the Core Audio Technology level 2 all in one machine. It will have everything you need except speakers, supposedly makes cable choices and power conditioning irrelevant (I'm skeptical here) and goes for around $4k with a 30 day guarantee.

I'm waiting for a local buddy to get one so I can demo without popping down the cash. It seems to have a lotf promise.

I agree with Jkj25 above that you should separate the amplifier from the DAC. Yes, I know it means two boxes (and maybe more money) but it gives you maximum flexibility to select the best amp and the best DAC for your system. It also enables you to upgrade one piece and not the other, if needed.

the new ModWright Integrated has an built in DAC option and it is in your price range.
