Help me choose amp for 2-channel HT

I've been using a Panasonic XA-45 AV receiver for the past 9 or 10 years in my TV system. HT only and two-channel only. No video goes through the Panasonic, just digital audio from the TiVo via Toslink and the DVD player (Oppo 95) via coax. It's worked fine, but I want to explore making a change in the interests of getting better sound. I was running Rega RS-5 speakers for quite a while but now have Revel M106, though that could change. Let's say a budget of around $1K.

I'm assuming I can get an integrated amp rather than an AV receiver, since it's only two channel. Would like sub out and headphone jack.

Should I get an analog integrated amp and let the TiVo and Oppo do the D2A conversion? How good are their built-in DACs? (I'm thinking NAD 326BEE or 356BEE, for example.)

Or should I get an integrated with DAC built in? Something from Peachtree perhaps.

If I got a new Oppo (103 probably) I could feed the TiVo's HDMI to it and let it handle all the video and audio processing, then feed the Oppo's (analog) audio out to the integrated amp or its (digital) audio out to the integrated if that has a built-in DAC.

I hope this is clear. I'm sure all of these options can work, but I have no feeling for whether there's a clear best path.
