Surround monitoring is really an annoyance. Though avid has them built into some consoles, there isn't a cost-effective standalone solution. We tried the spl, but it was insufficient. For a more-or-less traditional surround mix room you probably want a studio comm 76/77 - which is around $3500.
We ended up with a second hand martinsound multimax ex- overkill, but good. No aes input, we use an old protools 888/24 io for d to a. (Don't use the avid version- it doesn't work standalone.)

AlternativesI offer:Your Grace DAC will do you no good as it is stereo only.Concerning audio only, you need two things that you don't have: (1) an Avid-compatible interface processor (such as your suggested MOTU HDX-SDI) to get the Avid media into and out of your computer, and (2) a monitor level controller to allow adjustment of your speaker levels. If you are fond of Grace Audio products (and can afford them), the Grace M-906 is the perfect monitor controller for 5.1 audio. It's all digital and can accept AES directly, thereby maintaining an all-digital path. It can also be configured as the DAC for all of your speakers: http://www.gracedesign.com/products/m906/m906.htmBut it is expensive and overkill for your needs ($6000). The best substitute for the Grace is this one from Coleman Audio: http://www.sweetwater.com/store/detail/SR51mkIIThough it is analog only, it's well-built and should do all you need. It's connected between your interface and the powered speakers and not only allows control of the speaker levels, but can be set to monitor 5.1 in both stereo and mono to check for compatibility. Individual speaker muting is also available. The Coleman is one fifth the price of the Grace unit ($1100).In addition to the MOTU HDX-SDI (I'm not sure if it's Avid-qualified), there are other interface units that will work fine. My favorite is the AJA Io XT. This Thunderbolt-connected device provides all the ins and outs you'd need. While audio input is digital SDI only, output can be analog or SDI digital. The 8 channels of balanced analog audio outs come from a 25-pin D-connector which can be broken out to XLRs. AJA Io XT is Avid-qualified and is actually priced about $100 cheaper than the MOTU at $1500: https://www.aja.com/en/products/io-xtDennis Degan, Video Editor-Consultant-Knowledge BankNBC Today Show, New York
