Just a little happy note on the Hugo - two different moments today:
1. I bought an album off iTunes (pause for collective sharp intake of breath for Head-Fier purchasing MP3 from Satan's spawn). For anyone who likes rock, it was the new album called 'Wonder Days' by a UK band called Thunder (showing my age). When I got home I plugged the iPhone 6 into Hugo via optical, with decent over-ears (Denon D7000) and listened to it via Onkyo HF Player (which I believe upsamples - over to experts to clarify), and it sounded fantastic. Had to pop out to supermarket, so took the iPhone + Hugo but swapped the Denons for my Earsonics EMS6 IEMs. Again, fab.
2. Signed up to an online live gigs website called iConcert. Plugged Hugo into IPad - again via optical - to watch a 1990s ZZ Top live concert in Germamy. Again, sounded absolutely fantastic through the Denons.
My daily commute DAP is an AK120 modded (the Singapore dudes rather than Red Wine), and it sounds great. (I'm waiting for balanced cables for the Earsonics and my SE846s from Ted, which I know will be even better, and I may get the Glove Audio A1.) The AK120 already sounds better than the iPhone solo (both single ended). But the iPhone / Hugo combo using HF Player, with single-ended, destroys the AK with single-ended.
We are lucky to have such good choices. I've never regretted the Hugo, especially for mobile listening.
