Topic: Sound quality of Babyface, ADI-2 and Fireface UC? Unbalanced use?
In the next few months I will start making stereo music using virtual synths on my PC and vocals recorded elsewhere by my singer. My present audio interface is a TC Electronic Desktop Konnekt 6, which I've only had for a few weeks. I have no complaints about it: it's just that it has become clear that I will need something better. The only analogue input I will need, for the time being, is a mic input so that I can give my singer a rough idea of what I'm aiming for. If necessary I could keep my existing Desktop Konnekt 6 for this purpose.
However, it's difficult to predict future requirements, and I can therefore think of possible arguments (in terms of price and flexibility) in favour of getting a Babyface or an ADI-2 or a Fireface UC. (I cannot possibly afford a more expensive model). The factor that makes it impossible to decide, for the moment, is that I don't know how these three sound compared with each other. Since I want to get the best discount I can - or buy second-hand - I cannot ask a shop for a demo. If anyone could offer an opinion on their relative sound quality I would appreciate it.
My second question arises because I use for monitoring a domestic hi-fi whose pre-amp only has unbalanced inputs. Can any of the above be connected to unbalanced pre-amp inputs, given a suitably wired cable, or would this be a problem?
Thanks in advance.
Update: I forgot to mention that I also have an M-Audio 192, which has an SPDIF output. Would this be suitable for use with an ADI-2? Please excuse my ignorance.
