Ah So-So Not too bad Not Too Great Either
Okay well I just got my m905 hooked up via SPDIF from my symphony i/o running Pro Tools HD v12.4 on an HD Native card. Got a Wunder Audio CM-7 tube condenser mic and a Royer R121 ribbon mic hooked up on a heritage audio DMA 73 preamp (I do crazy mic'ing techniques in stereo a lot).
I have to say the controller is really great and it does all that it claims but quite frankly I think I'd rather have spent my money on something else instead (like a Symphony MkII!!!!). I mean this is "so-so" or as they say in Spanish "Asi-Asi" - I can live with it - especially when I hook my yamaha HS8 monitors up to it and then a subwoofer later on. It was kind of funny I thought I was not getting any signal but it turned out that I just didn't have the dB up high enough - yet another really stupid mistake on my part go figure. I am shocked quite frankly that audible levels are around 85 dB on the headphones (haven't tried the speakers out yet). It gives off some transparent sort of sound no color to speak of which is what you want for monitoring. The good part - its great to use as a "hub" if you will for your headphones, speakers, subwoofers, etc. but as far as sound quality I'd bet my money on the 1/4 in. headphone jacks on the symphony i/o just my two cents. Okay just set the presets up to + 20dB now its audible around 60-ish dB. Doesn't really matter truth be told but I really like the 0.5 dB increments that it goes in that way you can get a perfect volume level. Also you have to take into account the microphones, the preamps, etc. All in all, I'd say sure its okay I mean I'm stuck with it but honestly folks, spend your money elsewhere unless you REALLY need this. Its sexy no doubt it delivers on what it says its just not something I believe I really needed for my applications.
