Dear All,

I am contemplating to buy a RME ADI-2 Pro FS and use it mainly as DAC and headphone amp. Nevertheless it occured to me, that I could it also use as a premp for my stereo system, replacing severals other devices (preamp, separate DAC and separate headphone amp) at the same time.

My setup is as follows and I can't quite grasp, whether this is feasible or asked too much:

1. I use a miniDSP 2x4 HD as a 2-way crossover, feeding my power amps - it also is used for room equalisation and to tame my Fostex 206EN full range speakers (below 280 Hz they are supported by two 15-inch drivers per side)
2. All sources are connected via a normal preamp (an older Primare NP-30)
   -> that affords redundant DA/AD conversions, which I would like to eliminate by

- replacing my existing preamp with the ADI-2 Pro FS and feeding digital out directly into the miniDSP
- nevertheless I also need a analogue out, to feed my Stax headphone amp (obviously with fixed level)

in the worst case I could replace the miniDSP with an anlogue crossover, but than room correction and and a minus 10db level reduction @ 7-8kHz for the Fostex drivers would afford another dsp, because the ADI-2 Pro's EQ is not sufficient for room correction, I guess.

I could also substitute the miniDSP with a Behringer Ultradrive Pro for correction, which might electrically a better match to the ADI-2's AES/EBU output. The disadvantage would be, that currently the miniDSP is hidden somewhere behind the rack, whereas the Ultradrive would visibly occupy rack space.

My systems sounds nice to our satisfaction, but it maybe overly complicated with at least one conversion step, which I could potentially eleminate (now, from my existing preamp to the miniDSP).

So, if an informed mind could provide some information on feasabilty and suggestions for improvement, I would be very grateful.
