Isn't the HiFace a USB-to-SPDIF re-clocker/interface? You'll still need a DAC to plug it into, if that's the case.
I'd recommend that whatever little DAC you get be a DAC only. The Meridian, for instance, is a DAC + amp, afaik, even though it's mostly marketed as a DAC only. USB-powered DACs are already quite compromised (price-size-performance ratios), so getting a DAC+amp combo would be a further compromise, in that regard. In this particular market-segment, I think it's best to go for the models that subscribe to the "do one thing and do it well" formula. The Concero that Llloyd recommended above sounds like a decent DAC, though I'm not sure how much it costs or whether you'll be able to fit it into your budget.
Also, I don't recommend you purchase the Bakoon (or any amp) based on reviews only. I realize that it's difficult to get a a demo where you're at, but still, it's a bit of a risk. While (imho) the Bakoon is an excellent amp, it does have a certain signature, particularly from it's current output. This signature might or might not be your cup of scotch.
Fwiw, I have no experience with the Naim DAC you mentioned, but Bursons are by no means inferior. I have a Soloist (which is pretty much a Conductor without the in-built DAC), and while the Bakoon HPA-21 is clearly unsurpassed in certain categories, the Soloist can hold it's own in others. Instrument layering in the midrange and upper bass region, for example, is very good on the Burson. While the Bakoon exhibited more detail and control at the low-end, I sometimes wished it had the Burson's bass impact for certain less laid-back music. I can get into a bit more detail about differences between the HPA-21 and Soloist with the LCD-3, but they'll obviously be subjective. Just ask if you're interested, or PM me.
Horses for courses, as they say. I realize this is a Bakoon HPA-21 thread, but if you're able to actually audition a Conductor with your LCD-3 and like the sound, then by all means go for it. I reckon it's a pretty good combo, though personally I'd opt for the CM6631A USB receiver upgrade (see Burson's website) if I were getting a Conductor for myself.
