Top notch integrated vs DAC direct into stereo amp

Totaldac has something called the D1-Driver for people who want to go DAC direct, this might me an option : http://www.totaldac.com/D1-driver-en.htm

Audionet describes their Humboldt as Stern + Heisenberg.
That with a great DAC would be killer.  So would the Stern + Heisenbergs.

The Humboldt power is listed as : 
Output Power 2 x 320 W into 8, 2 x 460 W into 4.

The Heisenbergs would be:
Output power:530 W into 8 Ω
1,050 W into 4 Ω
2,100 W into 2 Ω

So the difference in a companies Integrated vs it similar separates is often the power rating, which you may or probably may not need based on your speakers and room.  And you save a pair of (expensive?) interconnects with the integrated, and save considerable space.  Those are the main reasons to consider integrated vs separates, to me.

Forgot to comment about DAC direct into Amps.  Tried this a couple of times, and both times when a good preamp was inserted the sound improved noticeably.  My ONLY source is my DAC and I still will always have a preamp (until I get the Humboldt!!!).  Ken

If you only have one source, then why not?

Well guys a guy that owns Stern + Heinsenberd + Totaldac Twelve compared with and without Stern just adding a Totaldac D1-Driver in place of the Stern.Suprisingly he liked better the presentation going direct into Heisenbergs without the Stern in the chain.I could get a very good deal on a pair of Heisenbergs.
