First of all thank you for Ian and Rudi for introducing this amp to the world.
I found out analog squared paper after seeing ianmedium posting his tu05 with pf on portable rigs thread. It absolutely the most beautiful rigs i have ever seen.. And I directly find a2p facebook and like the page. I also subscribed this thread right after.
I actually want to order a tu05 amp, but after reading Sean review I made up my mind and order the tur06 instead.
After 3 long month waiting there it is now..
Just receive my tur06 2 days ago...
I asked Mr. Shikada to make a special ak100 pocket for the amp, and this is the illustration that I send to him:
I need this special pocket as my interconnect is so stiff and i don't want to take it on and off every time i want to shuffle my music.
And this one is what he made for me:
that is the exact replica from what i draw to him.. Yes he is a very nice and great guy.
As for the sound, this is the best portable amp or even a desktop amp i have ever heard. This scale up all my headphones quality by large.
I use xduoo xp-1 before (it suppose to be a very good pair amp for an ak100 and very popular in Japan especially the xd-1 with optic interconnect). Yes it was until i just heard this amp for the first 5 minute. I put a really high expectation on this and this one simply far beyond my imagination,
Now i have been using this for about 10 hours (I have not recharge it since the day it came). I know it is not at its best yet but the sound is amazing and so analog..
He did mention on his mail:
I tried to use the attenuator of the current type.
The sound is better than voltage type.
However, it is not will be a mute.
(up to -50~-70dB)
I don' t quite get it what he meant.. hoping someone from this thread can explain more about this, ( I am very bad with electronics like the opposite site of GG).
And sometimes there is a bit analog noise at the background but not all the time, I have tried cleaning the tube with alcohol It is a bit better now.. Is it normal?
And the clinging noise every time i move the amp.. but it is getting less and less when the tube is warm up,
Again thank you for this beautiful thread hope i am not bored you all..
