Totally agree, at £600+, you start bringing other very competent gear into contention. Especially if you're ok with used off of eBay / head-fi.You should set up an export business on the side. Mojo 2 $775 USD. That's roughly £615. I'm sure Chord wouldn't be happy though.
I agree it's an easy sell for what you pay in the UK. For the US market, that's a harder sell. I love mine, but at that price point, you can get several other nice DACs.
But for under £400 new... deal of the year in my view.
