The a100tb is setup the same way as the BA300s. 4.4mm input, and 4.4mm output. Both of these amps are intended for 4.4mm balanced input only, and balanced 4.4mm output to IEM/Headphone. The 4.4mm output from the Sony is plugged into the BA300s input. The a100tb is the same.
The general rule is to not short the balanced channels together, whether on the DAP side, or the AMP side. So a balanced amp input should be fed with a balanced output from the DAP. Feeding a 3.5mm output from the DAP would short the AMPs separated channel circuitry together, which is not recommended.
The 3.5mm single ended plug uses a common ground (L, R, L+R GRD). The 4.4mm blanced uses a L+ L-, and a R+ R- signal, with the balanced channels usually comprised of 4 amps, which operate in a differential mode, 2 per channel. So the different configuration is the reason why it is not recommended to short balanced amp grounds together, which you would do it you plugged a 3.5mm Single Ended plug into either side.

Thanks! That makes sense, only thing I’m still a bit confused by is whether to use just a normal 4.4mm to 4.4mm interconnect, or use something like the attached photo to take advantage of the grounding the Sony 3.5mm offers (meaning you plug both the 4.4mm and it’s piggyback 3.5mm dongle into three sony at the same time).

hello all, any idea if there are stores selling the WM1ZM2 in Narita Airport? will be stopping over in terminal 1 and hope to pick one up at a duty free if available - am guessing language on device won't be an issue/other caveats for JP model

thanks guys!

Narita Airport

This 6 are Sony dealers, worth giving them a go.

You can buy tax free on almost every eletronic shop in Japan, or even good condition used ones at akihabara. I

f you arent leaving the airport im not sure you will find it on the airport, those shops are actually small and focus on things that sell more easily.

I am using this kind of cable to connect my walkman to external amps, and it really helps reduce noise, and make a dark background as the walkman standalone. Especially on some amps the power supply is not clean, in my case the Xduoo MT-604, without the connected ground, the background is too noisy.

Not needed in all cases. Lowers the noise floor and cleaner background for lower impedance iems and headphones. My Campfire Solaris have buzzing with amp. My audeze Euclid and fatfreq Maestromini do not. So, it depends on the headphone/iem on whether or not you need/should use that special type of cable

By the way, i had no issues entering Frankfurt Airport with my WM1ZM2.

The customs were completely closed, you could just pass without any inspection at all. If you would have had something to declare, you would have had to call them by phone.

Tell them it’s an mp3 player - no one will believe it’s cost more than $500. Or take it out of the box. I’ve never paid any taxes for anything I’ve ever bought abroad

 

[Vamp898]

I, of course, left the box and everything in Japan. I plugged headphones into it and kept it into my pocket. At last at that point, nobody cares

What? You didn't post the empty box home!!!

 

[Vamp898]

I am moving to Japan right now, im only back in germany for the last few things i have to do here. So the box is right where it belongs to, in its home country^^

I searched based on the stores here (T1), but could not find the item on their webstore hence am asking here

alright hope it's available in the arrival hall of T1 Narita, only have an hour there so abit worried

A sad passing of a Singaporean who made important contributions to computer audio and portable music players. He made computers able to produce real world sounds instead of just beeps and boops.
