More than fine. RSA Predator will do it too, but the LCD-2 isn't really that unforgiving of bad source, just make sure whatever is going into it is alright and you'll be happy if you already have an SR-71A.
If you need a compact amp that isnt' terrible to ship, I have experience with the Audio GD and a few other sub $500 dac/amps and I can say that AGD is great bang per buck in a small package that won't cost you $100 in shipping.
What do you mean by bad source? Is it the music file quality or the device which is playing the music. If you are talking about the device, will a iPhone 4S suffice or I need to get a receiver or something. Btw, is a receiver like a desktop sized amp?
