Well, I've had it for a couple days now and I'm really liking it. To me it has a very warm presentation, but then again, my amp, as well as speakers both are known to be warm and non-fatiguing. So I really can't tell if it's the DAC itself or the whole system as a whole. I do enjoy it's sound as ever since I hooked it up I've been ripped away from critical listening and have just enjoyed listening to music. Take that how you want it, but for me that's a huge plus.
So, would I recommend it? Yes, definitely. At the price they're selling it for right now, it's a steal. The machined remote is very sturdy and has a solid feel to it which I like a lot. Couple that with Emotiva's great warranty and customer service and you have a product that will take care of you for a while.
One thing that I did notice is that it's output via single ended is only 1v max. So if you have hard to drive amplifiers this may not exactly work for you. Or if you have a high gain amp and relatively efficient speakers you may find that the minimum volume setting is pretty close to background listening levels. Some people have complained about this but I actually don't have a problem with it. The amp I'm currently using has adjustable gain so I can match it with pretty much any preamp out there. If you find that even on the highest volume setting you're still not getting the output levels you need, you might need an external preamp and just set the volume to 80 (max).
Another thing you should know is that unlike more of the common DACs on the market, the XDA-1 only accepts sample rates up to 24/48Khz via usb, whereas the standard usb rate extends up to 24/96Khz. Again, not a problem for me since I don't have any super high res files, but if you do, you may want to think about running a Musical Fidelity V-link out from your computer and then into this DAC to take advantage of it's 24/196Khz via digital coax and optical inputs.
Well, that's about all I can think of right now. Emotiva has beautiful pieces of equipment that perform far beyond their price point. Along with their customer support they are definitely a company I can suggest to those wanting high performance audio gear on a limited budget. They aren't the last word in hi-fi but get you pretty damn close and for a fraction of the cost.
Cheers,
Steven
P.S. I just picked up their ERC-2 transport and am in love with it's sound. The ERC-2 and XDA-1 were made to be together. Another Emotiva steal of a deal if you need a one trick pony transport.
