after a long time not using them i remembered why i bought the tu-05 and plugged my fad pf viii in.
what i hear is unbelievable homogenous, the cave like sound experience, and now i much better understand the postings in the fad appreciation thread. all the harsh resonances i had the feeling to hear before are away, a beautiful and relaxing sound, black silent background (between two tracks i had a look at both amp and player if one of them would be out of battery) and so sweet and nice, real magic. goog luck that i avoided to post anything in the fad thread before having this amp.
right now i am listening to windham hill records - cinema. the windham hill recordings seem to be perfectly made for the piano fortes.
if one of you have some of the windham hill cd's, you should give them the chance to be listened to with this amp and the piano fortes!
i looked for the translation of a german word, the shown result was 'goose bumps', i think no need to explain why i was looking for that ...
and i tought it would be a German(Guy)-Grado,
but as Franken is a region in germany ,
or do you really mean the F******stone sorry F******stein
i also love battery powered devices and especially that a lot of problems with hum of a standard power supply or RF and high frequency interferences and noise of a switching power supply can't appear. i developed combined analog and digital parallel computing high speed online measurement systems for more than five years and a notable part of the effort had to be spent for the proper design of the power supplies and solving all the problems with them.
but i think the most important part of the story is that shikada san is a genius in developing tube amps, it's the combination of concepts, battery powered, the strong internal 2.2 ampere battery, the small batteries for the precise tube bias reference voltage, the selection of just this tube types (for example i could think that the low voltage and small heat results in less random electron movement and transmission, i.e. less noise than hotter driven tubes and amps).
i am sure he had a specific vision in mind how to build the perfect tube amp and when listening to the result he is able to deliver with such a small amp i don't even could imagine but would be very interested to listen to the result when his first big amp is announced for sale!
I really lost counts when did the tubes hunting.
Even up to now, I believe I might missed something on the list.
But frankly speaking, I was a bit surprised to realize that I've ordered that much.
Ian, thanks again for such brief and precise description.
It's really exciting to understand these tubes characteristics and their historical tributes.
if you need someone for counting, i herewith offer your my willingness to do that, just send me your tubes .....
charging and getting charged:
at the moment i have to charge my tablet twise a day to read all the and write some posts. i have to charge my colorfly c4 twise a day, during night and after work to listen to music and also my amp is constantly asking for breakfast and dinner.
the only things that get charged automatically are my bank account and my credit card.
thanks a lot for this idea - i will follow this idea as you gave me the design direction i now can think about and had no good idea up to now.
