I should be joining the D2 thread next Monday. I am a big fan of Anthem electronics having a 510 upstairs, a 710 downstairs in my listening room (pre, pro, and amp at this point are in use). My listening room is small so ARC helps immensely. Toggling it on and off is a stark, and positive change.
I am about 95% stereo, 5% multichannel audio, no video/movies in this room. Of that 2 channel number, about 95% of that is from my turntable (George Merrill PolyTable "Super 12" for anyone curious) so I route analog into the 710, it gets processed and amplified out to Dyn Focus 260 speakers and two very carefully-set up SVS sealed 12" subs. I don't like "boom" but I like bass I can feel, just the way it is.
So, I found on ebay today a D2 with Arc for $999. I jumped on it, as that's quite a bit lower than I remember seeing on any other used audio gear sites, but I know it isn't the deal of the century by any means. I'm wondering just how much, if any, improvement I'll see over the 710 with how I'm using it.
I do have an outboard amp that should be returning from service later this week, an Odyssey Audio Stratos Plus with a few upgrades done to it. In the meantime, if that's not back by next monday, I will set up the 710 to be "direct mode" or whatever they call it, and have to somehow deal with having two preamps in the chain until I get my Stratos back, but effectively using the amp section of the 710 only.
Once the Odyssey gets back, I may move the 710 upstairs and offload the 510, I'm not quite sure on that yet.
Either way, I'm excited to see how the improved analog and DAC sections work in the D2 compared to my 710. Maybe it won't be much of any difference? I'm not sure.
Now to hunt down a long serial cable...
