I’ve had my ZX-507 for ~6 weeks now. It’s a Japan domestic model; ordered off eBay, and including stupid AF sales tax (ugh…trying not to rant about sales tax I had to pay for a purchase from a Japanese seller via eBay, and my state having zero to do with it), it was $770USD. Shipping speed was beyond impressive. I had it in my hands (I live Midwest U.S.) less than 48 hours after placing the order.
I have always been a bit of a Sony fanboy, to get that out of the way. I have ~225 hours on the 4.4mm balanced output (including initial time “burning-in”…don’t want to start a religious war about burn-in). I think it sounds amazing. I have minimal gear as someone who sold a BUNCH of stuff ~5 years ago and left the hobby until recently. I own -zero- headphones (frankly, I admitted to myself ~5 years ago that I simply am not a headphone guy), and the only non-smart phone IEMs/buds I own is my much loved Sony XBA-Z5.
I was considering other DAPs when I purchased this (I sold my 6 year old Astell & Kern AK120ii about a month ago), but settle don Sony as trustworthy from a build quality & software standpoint. I have zero regrets.
I have never gotten into streaming, so 100% of my current use is with ALAC (mostly 16/44 but some 24-bit as well; I’m a Mac user, thus everything gets ripped/transcoded to ALAC). However, I can see myself eventually trying Amazon Music at some point.
As a Android device, battery life isn’t as stellar as the non-Android Sony DAPs, but in real life, I got not quite 18.5 hours of 16/44 (with some 24/96 as well) ALAC playback when I did a 100% to shutdown run down of the battery (for calibration purposes) last week.
My sole setup is neither sexy nor cutting edge, but no longer being in my twenties, I just have zero desire to be an early adopter, or spend time modifying gear. I like things to just work. And yes, I am willing to pay a premium for that.
I’m glad Chi-fi is making noise. It’s good for we the consumers. However, I’ll let y’all be the beta testers for all those companies. I’ll just chug along with my minimal, boring gear, hahahaha.
