It's largely in the title really but I'm considering picking up a UX8, despite them now being discontinued (I think...) because it seems as close to what I'm looking for as I think I'm going to get.

However, on forums and elsewhere on the internet, there has been mention of the latency and particularly the round trip latency when monitoring through a DAW not being good enough for live use. Is this true? What sort of figures are we looking at with the UX8 on a Windows 7 64-bit machine with an Intel Core i7-2600K and 8GB RAM?

I realise a definitive answer may not be possible but I thought I'd ask anyway. Thanks.
