i can't believe, but after joining head-fi on April, 2013 this now is really my post #1000, and i am happy that it is in this group and thread.
 
 
P.S. i coudn't resist to quote my post  "how everything started"
 
Quote:

  as time goes by - reading this thread i just recalled how everything started. i originally joined head-fi after by chance i bought a final audio design piano forte viii at the this years high end fair in munich. soon after that i had the problem that none of my amps seemed to fit the requirements or give me the sound experience i was expecting, so i joined the final audio appreciation thread and asked for a recommendation for an excellent amp. soundfreaq wrote a nice welcome message and asked another member with greater experience to answer my question. i got the recommendation to have a look at the analog2paper tu-05 by someone with the alias 'ianmedium' !!!
 
(cannot send him enough thank you's for that)
 
so i joined this thread with my first post on page 17. some time and 40 pages later i can say that i would really miss this thread if not existing  and all of you here sharing all the ideas, experience, humor, the whole spectrum of topics, the open and friendly style!
 
and now ... wow ... only some days left and i will have the amp (and lots of tubes) at home to listen to.
 
p.s. i have reactivated my dslr photo and macro equipment to post some nice pictures of the amp after i got it and maybe to join the fad piano forte photo contest (i bet never reaching the level of woodcans exceptional images). at least i did some functional tests so here you can see a picture (out of camera, only resized, uncropped, unedited) of what happens with a fad pf viii if you have not used it for a long time

in my email exchange with shikada san i also mentioned the hd800 and shikada san answered, that he can provide custom made (but very expensive) special core output transformers for the tu-05 to drive the hd800, so maybe this is also an option.
 
as posted i found two nice and relatively small output transformers that could be used with the hd800 fitting the specs of the tu-05, i think i will connect and test them during the weekend rebuilding my at the moment really desktop version of the tu-05 (all the different components unconnected on my desktop and without power for the led's due to the partly damaged internal psu board), but i have a new aluminium base to mount and assemble components for test purposes.

 
Thanks GG, since my 05 is still under production I'll contact Shikada-san to see if this is an option. I'm getting spoilt by the ALO Studio 6 driving the HD800, a truly magnificent pairing. Will report back on response.

yes, and let's forget whatever was, have removed you from my blocklist!

 

[ianmedium]

yes, and let's forget whatever was, have removed you from my blocklist!

See, this amp brings us zen as well as sonics!

 

[smial1966]

Many thanks GG. I now feel a proper member of this threads community again.

Your ingenuity and resourcefulness sourcing audio parts astounds me, so keep up the great work as we all enjoy reading your modders diary.

Had the TUR-06 running for about 5 hours and brief thoughts are the TUR-06 is a far more traditional tube sounding amp
 
- good sense of immediacy with main images fleshing out very nicely
- nice ethereal presentation of the highs
- bold prodigious bass with emphasis in the mid and upper bass giving warmth to the signature 
- not so high in detail retrieval but very tuneful and euphonic
- mids are very sweet
- vocals takes center stage, with very good portrayal of nuances and micro details
- soundstaging is very wide but seemed stretched and slightly unrealistic, depth is well portrayed
 
Please read the above with a pinch of salt! Will try and make direct comparisons with the TU-05 in the coming weeks, when the TUR-06 has fully settled. 
 
With the current USD/JPY exchange rate, I highly recommend the TUR-06.......................................

UBER cable  AND UBER  IC between AK & TUR ?

@spkrs01 That is my dream rigs, rwak100-s + uber interconnects. Sound must be incredibly clear and beautiful.
after the tube settled in the sound will be much much better. it took about 3 charge cycle on my amp.
 
Last night instead change to my 2nd phillip set, i try my other tubes on the tur, first one is the telefunken df96. I think the tur has the biggest stage when using this tubes. Rustling and tinging sound is gone after just few minutes listening. they also make my ath sound like an open cans.. which i don't like. the sound is too light for my taste. there are some refinement but overall it simply just too linear across all frequencies. the mid gone back. and the bass is become very light.. After two hour or so of listening i just got bored and try my other tube which is the radio technique it4. The tubes doesn't make any noise at all. interesting.. the sounding is pretty much like the philips. the bass bit less than the philips. mid also sent back a little further than the philips.
 
Then I decided to use the philips for the tur for the next couple of weeks.  I use the 2nd set and the little rustling noise still there. oh well i think it just need more time to settled in than my other tubes. Maybe it is the tur06 bug that Shikada mention on the a2p facebook. low freq distortion.. he already fix the problem on the tur-6 #5 and #8.
 
to sum up purely based on my opinion only:
vocal: silvania > philips > rt > telefunken
bass: philips > silvania > rt > telefunken
instruments reproduction: philips > silvania > telefunken > rt. note: piano sound on philips are simply amazing!!!
staging: telefunken > silvania > philips > rt
 
Overall the silvania tube still my favorite.
 
Have a nice weekends guys!
 
p.s: i tried mixing the tube like silvania and the rt. but it is not a good idea since it get imbalance depends on the recordings.

so everybody now can run and charge his tu-05 even with USB.
 
@Sam Edwards - hope this helps !

Hey GG,
Are you suggesting that I build a new power supply board for my TU-05? I'm sure I don't have your mad skills, Brother. It's unbelievable the things you accomplish. Where did you go to school? 
Do you think there's any impact on the sound? I guess you can't test it in the TU-05 until you get yours fixed. 
Do you think that Shikada San would build mine with your schematic for the power? He says my unit is delayed.
