BTW the DAC in it isn't really spectacular (do consider that I listened to it moments after listening to Cayin CDPs) but the amp section, as far as it being a convenient one-box solution is concerned, is quite surprising. It was able to power a pair of Duevel Planets, which are in the mid- to low 80db+ sensitivity range, loud enough (for me) and without clear signs of running out of steam.
Well, the thing is with these devices nowadays is they're trying to get around the problem that digital iPod docks had with speaker systems - that is, if you have it in a pure audio set-up instead of an HT set-up (or both in the same room) - you won't be able to see the screen and you have at least 30gb (iPod 5g) of music in it, so you'd end up walking over to switch albums or add a display. Instead of engineering a remote with a screen that will add to the cost of the device, they're basically assuming that everybody has a smartphone or tablet to begin with, so they all just went for remote apps. Even A/V receivers nowadays have remotes that get more plasticky at every upgrade given an iPad or iPhone feels infinitely more solid, and it seems like only CDPs will retain those remotes you can use to knock out a burglar with. Add to that how often remotes get lost while a tablet can locate a phone (and possibly vice versa), and either one can be used as a remote anyway.
For your situation though, check the specs of the X10 for this, but I think you can stream audio to it; wireless with the antenna or maybe even ethernet. So basically instead of "controlling" the X10, you can use a PC (notebook, or even your desktop) to stream audio and the X10 basically acts as a network audio receiver. It's available without a bundled HDD anyway, but check if it comes with the antenna. Local dealer here sells it slightly cheaper without both but for about $150 more (which is basically the cost of a 1TB HDD and the antenna) they will bundle Castle mini monitors with it.
