Topping D50
Do you have the link to the details of that? What is the reason for this design change and what exactly has been changed in the hardware?- KonstantinN

Well, i do not use this services and can not answer for sure. Would not like to speculate. Try and post the results here :-)- KonstantinN

Topping D50
On your pictures i see it shows bit depth - 32bits. Mine does not show bit depth for PCM streams from any USB sources, including PC. What is the firmware version of your D50?- KonstantinN

Topping D50
Hello. It works like a charm with my iPhone and camera adapter kit. PCM and DSD over PCM up to DSD128 - no problems. Neutron player, HiBy music player apps are capable to play SACDs from network source to D50 (DoP mode). Hope it clarifies the case. BTW, Topping D10 also works fine with iPhone...- KonstantinN

Question to ATH-W5000 owners
Absolutely true. I had to perform headband bending (see picture, took 24 hours to adjust the shape) and change the ear pads to a thicker ones (custom, lambskin) to get great fit and better isolation. But the sound is that beautiful, that i am not disappointed.- KonstantinN

Topping D50
In the new D50s they changed the output opamp. If someone has both D50 and D50s, I am curious to read sound difference impressions.- KonstantinN

My D50 does not show PCM bitrate also. Out of the box. Looks like they removed bitrate display starting firmware 1.02.- KonstantinN

Topping D50
Making conclusions about sound impact of one of the sound system (source-to-ear) component based on READING does not sound correct :-) To me D50 sounds very musical and detailed at the same time. Not fatiguing at all. I listen to it with headphones. A900x, W5000 both sound differently but great.- KonstantinN

Why? Any issues? I used to use it with Synology NAS and iPhone - works like a charm.- KonstantinN

Which (if your measurements are correct) with OPA1612 PSRR of 120-140 dB means 4-40 uV noise impact on the output - peanuts.- KonstantinN

The "Lovely Cube" Headphone Amp (Lehmann Black Cube Linear Clone)
Too generic statement. My answer was about specific components (capacitors) at specific place, playing its role in specific function (Low frequency filter). I do not know this manufacturer and never saw a data sheet for the mentioned capacitors. Therefore - no comments from my end.- KonstantinN

I am not going to lecture you. And do not want to offend you in any mean. Instead, let me ask you a question that may give you an idea: how do you think +5 volt that is supplied to D50 becomes -8 and +8 volts supply rails for D50 opamps?- KonstantinN

The more, the better. While real improvement of the ripple is negligible after some capacity.- KonstantinN

The "Lovely Cube" Headphone Amp (Lehmann Black Cube Linear Clone)
Have tried negative feedback mod for the amp. It is a game changer for low impedance headphones! My 16 ohm 70mm driver cans have moved to a higher league :) Dynamic range and transparency have been improved dramatically. And the mod is very easy to implement - you need to desolder one end (the...- KonstantinN

f3dB = 1/(2*pi*R*C) Reducing the blocking capacitance value you decrease amount of low-frequency signals that will pass it. For LC 1uF is still fine, It means that 3Hz input signals will be decreased by 30%. The lower the frequency of the signal, the more signals will be decreased.- KonstantinN

The "Lovely Cube" Headphone Amp (Lehmann Black Cube Linear Clone)
This is also my first post here even though i am a long time lurker. Following the direction of chetlanin and bla-bla’s comments, i zeroed DC offset of my LC output by soldering 4 variable 50k resitors in parallel to the 1.5k resistors (R25, R28,R29,R32) on the schematic. A bit of nipples...- KonstantinN
