Digital Drive Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

Even if it doesn't there are other things to consider

1. The 32bit floating point may or may not be enough to do all of the math transparently. I suppose it depends on how much equalizing you need to do. I have no experience with the Behringer unit, but I can say that the prosumer stuff that I do own (such as AKAI hard disc recorder) doesn't seem to have enough bits for the 2Buss to make coherent mixing changes.

2. Lack of RCA S/Pdif. I guess if you are using the AES EBU connectors this is no biggie. I wouldn't want to use the optical though.

3. Switch mode power supply. *Ughhh!*

4. The low frequency implications to your amplifier. Let's say that points 1,2, and 3 are non issues. Great! However, if you plan on boosting any of the low frequencies by more than 3 dB, your amplifier will have to deal with that and your speakers will have to be able to respond to it. You might be trading room correction for clipping and harmonic distortion. On the other hand if you are only cutting frequencies then scratch that, reverse it.

At the asking price for a new one it will be fun to mess around with and probably worth every penny just for the education.
