So I replaced the two 1st Tubes (L/R) with
Mullard M8137, as I had great experiences with Mullard,
when I had the Thermionic Phoenix "11th anniversary edition".
(although it uses another Mullard M-Tubes).

interesting!

the sound difference is huge, you can't imagine that you used the same setting.
the original tubes sound snuffy, the mullard much more open, whereby I would like to listen in again tomorrow with fresh ears, the brightness could also come from more saturation.
the version with the mullards also seems to be much louder, something that is not confirmed by the measurements, but rather by the brightness and possibly by saturation.

your sound sample makes it a bit difficult for me to clearly recognize saturation, moreover, it is difficult for me to estimate the punch and lowend range of your sample.

i ordered the same mullards after your mail and now these new cryo-tubes from jj.
i will make a comparison of all diveser tubes to find the optimal combination for me!
