Ok guys today i am a very happy man because I just received my telefunken diamond base tubes. For this tube i just clean it with alcohol and tissue, the pins are not sparkling clean but they are clean enough i hope.
Okay as for sound.. Oh my.. just right the moment i turn the music on. It is the same feeling when I listen to my tur06 for the first time.
I listen to Ingram Washington album which is only 16 bit. The vocal is so soft but powerful (i always feel that df96 tubes have better power than the it4), lushfull with very good timbre and singer character voice are shown.. all the instruments including the cymbal sound so intimate, weighty, full dynamics and real. and the bass are the best i have heard from the tur06 so far. just right amount of everything.. detail retrieval also the best among my other tubes. Sorry for my limited language but they are really what i feel.
I kinda get the same feeling as when listening to a home speakers.. they really soft but full of detail and so intimate with unlimited three dimensional space of sound. I wonder are all tube amp can sound this good? even my df96 philips sound much less lively. I can't believe i said that because they were my best tube so far.
There is a little buzzing noise at the background. but i am pretty sure they just need a little more time to settling in because sometimes the buzzing are completely gone.
And my setup was hippo biscuit and fad heaven 2 with copper m2m.
I will post more impression when my ak240 come. hopefully in two weeks time.
Will post some pictures tonight!
Special thank to GG for helping me in getting this incredible tubes. owe you one GG.
- first of all i am absolutely happy that you like this tubes that much!. i also by far prefer them compared to the Phillips DF96.
- you are absolutely right with your feeling, the DF96 has a higher µ-factor, which means higher amplification than the DF91 / 1T4.
- the buzzling background noise may have the same reason as posted by AnakChan, you may need this additional LC-Filter because of the unstability of the internal power supply due to too low current, the power supply has only to provide 50mA for two DF96 for the filament power instead of 100mA for two DF91.
