Round 1: Anakchan kindly lent me some of his gear and I already have a couple of great DAPs on hand, so I thought I'd do an ongoing shoot-out between them. Anakchan lent me: HiFiMAN HM-901 with balanced card. Sony ZX-1. Getting music on to this will be interesting, but I'll figure it out. Cypher Labs Solo -db and Duet. I already have: Astell&Kern AK240. Mine. I have already made a balanced "tail" for my headphones and have more cables on the way. FiiO X5 (on loan as part of the World Tour). iPhone 5 I'm waiting on a couple of WyWires cable sets and I need to make a couple more adaptors so I can compare amps, eg: The balanced out of the HM-901 and AK240 vs. the Duet, but I have most of what I need on hand already. I'm quite familiar with the X5 and AK240 but I've only had one listen with the Sony (in comparison to an AK120) but the HM-901 is new to me. Preliminary impressions shall be posted soon... Edit: Here's my summary (which forgot to mention streaming with the Sony): Round 2, June 2014: FiiO X5, Astell&Kern AK240, Calyx M: Begins here. Round 3: Chord Hugo Round 4: Chord Hugo, Aurender Flow (not really DAPs, but everyone asks), Calyx M (1.01), Lotoo Paw Gold and our good friends the AK240 and HM-901. Begins here. Round 5: Calyx M, Chord Mojo, Soundaware M1 Esther, (AK100), Lotoo PAW 5000, FiiO X5 Begins here. Round 6 I think I need a second multi-port charger. Begins here. Round 7 HiFiMan enters the party along with Soundaware's M1 Pro and the FiiO X7, with no less than 3 amp modules. Begins here. 2017 Summer/Autumn updates: Eaglewings Lotoo PAW Gold versus Hugo 2 X7 Review Hugo 2 Review (3 videos). 2018 - 2019 Hiby R6 Unboxing and Review Bluewave Get HiFiMan Megamini iFi xDSD FiiO Q5 FiiO M9 Aurender Flow -- Because it showed up on Massdrop, I re-edited my review.
