Nice thing about the Peachtree is the DAC is built in and you get 80wpc if you go with the Nova, 50wpc with the Decco but less inputs. Both are nice and with a Sonos ZP-90 linked by ethernet to your hard drives, you can access all your music and/or play the internet radio stations (extra $36/yr for 192k streaming...well worth it) and you can stuff it into the back of the Nova which is really great.
You also said "yet" when you reffered to your monitors. Have any ideas there? I'm fairly keen to Monitor Audio due to the price/value for what you pay. I'll break it down real quick. Just an example what could be had for not so much.
Peachtree Nova $900 used.
Sonos ZP-90 $350 new ~$275 used
Monitor Audio RX2 ~$850 new ~$550-675 used
Assortment of cables $500 new/used
You'll spend less than $1,500 if you leave out the speakers and some replacement speaker cables. You could easily spend that on a DAC alone. And then you have to worry about your source and additional cables and quite honestly, when you step up to a nicer dac you'll want to upgrade your cables too. Classic snowball effect. Keep it simple.
If you go with an outboard DAC like a Music Hall and a new/used integrated you'll still be around the same price, if not more than you'd pay for the Nova. The Nova isn't the best piece out there. But on a budget? Definitely. I heard this thing streaming 128k interenet music through a Sonos player into a pair of Monitor Audio RX8s. Awesome.
