The most under-rated and over it's price point Sony audio product i feel is the MDR-1AM2. This headphone's sound quality is way beyond it's asking price. It's fun bassy sound signature works really well for Rock and Modern Pop Music. Easy to drive and very much sibilant-free(vs the ear piercing ATH MSR-7). If I must sell all my headphones and stick to one headphone for life/bring one headphone to live on a lighthouse for a year, this MDR-1AM2 will be my life choice.

Just an FYI, GaN technology back in 2012 was so bleeding edge technology that it allegedly resulted in this "mysterious" murder/suicide case of an american engineer in my country:

Fast foward to 2020, this GaN is used everywhere, even in my Anker 30w Atom Charger.

it is widely used, but there have been none that are dedicated toward Audio Regulators, switching FET ....etc.... most of them are into processor IC.

anyways, atm I am looking for DMP Z1 service manual LOL

CDs are stricrly 16/44.1? Bcause i have three Handel music CDs and my walkman says FLAC 16bit/48kHz.

Edit have ran a spectrum analyzer and they reach to 24KHz

Red book CD audio is 2 channels PCM at 16/44.1 but what your ripper converts it to during ripping could be anything

Never mind the question, ended buying the flacs from chandos records. The 16/48 were AAC upsampled to "Flac" (checked them with spek spectrum analyzer after they sounded odd on the walkman

Hi just want to be sure walkman wm1a is MQA compatible? if using it as dac via iphone lightning to usb, say for tidal, it is doing MQA transcode natively? thanks in advance :) love the wm1a, only missing is the streaming apps, at least in my use case,

No it doesn't have MQA decoding capabilities. That should not be a problem considering that MQA is a utter nonsense. This format was made to make money on licencing products and for streaming services so they can save storage space. Oh and it's lossy.

It plays mqa files natively. I don’t know if the Tidal app will send an encoded mqa signal to an external dac or if the 1A can handle a mqa stream in dac mode

Firmware 2.0 added APE and MQA decoding. Don't know the details of how much of the MQA unfolding it can do. As the change was done via updating firmware, I conjecture that the hardware capability was baked in, so it may be able to unfold fully. As I said, though, I don't know the details, so you'll have to do some research on that.
