You really should. The more I listen the more I am impressed with it. It is the best all-round DAP I've used to date. The build quality, ease of use, sound quality, power, interface, size, battery life; while the i5 is not the best in most of those areas, it is very near the top and no other device I've ever used is as good on every level.
The QP1R is more detailed, has a deeper/wider soundstage, and better bass with IEMs. But using it is an exercise in frustration (the clickwheel, it's horrible) and it chokes on SACD ISOs which are a significant part of my collection. It also doesn't sound as good with compressed (AAC/MP3) material as the i5 for some reason and won't push my TH-X00s to truly satisfying volumes without distorting. Yes, in high gain at max volume there's distortion.
The DX100 has far more power, but the battery life is woeful and using it is an exercise in patience and futility. I have waited 30 minutes for the thing to find files and start playing using a loaded 64GB card. I consider the i5 ahead of the DX100 in resolution, detail and texture.
The Plenue D has battery life that excels beyond anything else I've experienced, it has an easy interface and the size is great. But the sound quality is little better than a phone IMO.
The QLS-360 is hugely detailed, very powerful, takes full-size SD cards and is built like a tank. But it's as ugly as a tank, the interface is rudimentary at best, it doesn't do FLAC files over 44/16 (seriously!?), it regularly hangs, and is really only at its best with DSD. Even then it's bright, strident and analytical.
I haven't heard anything better for the money with the level of functionality it has. And that's even before I take into account streaming services and other Android apps (which hopefully I get working soon).
