There is a major selling point of this unit for me. I'll admit that this is very parochial and may be completely irrelevant for most, but I can drive to my local Richer Sounds (5 minutes, just adjacent to Milton Keynes Central railway station) and buy one of these. The price is not that much more than Topping, SMSL etc alternatives but I have the assurance of a local shop which happens to have a very good record for customer service and after sales support. If anything goes wrong on gear I've bought from them I can drive to the shop and my experience of their handling of such things is very positive. That is worth a lot to me, I know the argument is that these things are cheap, but they're not that cheap (personally I don't consider £250 throw away money).
On the technical performance, despite being a decade old the measured performance remains perfectly respectable and kind of demonstrates that DACs have been technologically mature for a long time despite marketing claims trying to convince us that they've been racing along technologically and inferring that if you replace last years model with this years replacement it'll transform your life. The DAC in my CD player is something like 25 years old and remains a good, solid performer.
