I understand the importance of digi-in, for there are many people who will not part with their favorite preamp. Myself included. Also, noise would be lower than a 1/8 connection. But if the ADC is good on the R09, as the R1, then cleaning up any noise at the 1/8 connection is all that needs to be done. Doug Oade has done that with the R1. I assume he will do that with the R09. That's why I'd have no problem hooking up a V2, MP2, or Sonosax to the R09. I'm strongly considering getting this.
As for the Microtrack, reading all the problems people are having, none consistent but often varying, I don't find it reliable enough to even switch from my trusty JB3. With the R09, I'm hoping I can dump the Deneckes (2 boxes) and just run a MP2 (1box). With the R09 being less bulkier than the JB3, my future stealth rig will be even stealthier. Heck, all I care about right now is 16 bit.
