Have an eye on changing the 6c45 tube as well, the only 6c45 that i can recommend are the good-old-time 6c45 of Soviet Union circa 1970-1980, they have excellent electronic characteristic and no vaccuum problem when running in high temperature like the EH6c45 gold-pin, which are sold for 100$...

      Mine, TV7 - D/U  Fast and reliable. 

No info and no link for product ? 

I also put my money in 3 models from the first starting campaign about more than a years ago and until now, they seemed to be one the sea or elsewhere :))

I have never listened to any crack otl but I've been living with 6080 for years, tried all 6080 of all versions and countries and found that the best was 6h13c from old Soviet Union. They do not magic, they do not make colorations, they do sound fine and natural.

    I have some nice pairs of 6h8c Mel-z from Soviet Union, which is one the the best kind of 6sn7 i've ever tried :D 

I've been to Munkong Audio in Bangkok and I hope to try this fabulous headphones, but poor me :( 

1) 100.999 2) 100.560 3) 100.001

i'm also interested !!!! 

the only thing that i've been worrying about is the speed. I've got a HM901, it is definitely a my superman on sound quality side. But I'm thinking of selling it after a month due to its speed issue. HM901 is laggy and a bit slow. Even when I play 16/44 or 24/96.  HM901S is 100% built with...

I'm about to get this amplifier http://en.questyleaudio.com/article/6 due to its fanstatic look. But the problem here, it is a current mode amplifier,which i don't know how it is different from my Violectric V90.    I spent times to read. People kept talking about the high impedance output of...

Hi Aaron !  This is a very nice review. This is 1st time i've ever heard about these technology. Does it mean that the air coming directly into the tube and then, will result in better soundstage and imagination?  I'm wondering how it sounds to my ears.  Btw , we have some new stuffs...
