today was a perfect day to integrate the GG2 in my set up.
So I tried some different tubes, collected from friends. I seems, that I am a hard lover of 300b tubes, as I am a mid range maniac.
Best performing tube (so far) was the TJ Full Music 300b / SE , which costs in Europe 1000,-eur / pair., The EML 300b had far too much bass in my set up, the Psvane WE 300b was just a little bit too sweet. (all with KR recti)
But I was still not fully satisfied, so I started to have a deeper look in the placement.
The GGII was staying on the original rubber feets on a HRS M3x platform (on HRS S1 Rack)
In theory the HRS M3x likes rubberfeets. But in this case, the sound was still too dull. I was expecting a higher resolution from a GGII.
I changed to the HRS Nimbus feets, which are 2 rubbers plus alloy.
Unfortunately the GGII was still not performing better, I had the feeling, that the GGII was even loosing some more resolution with the Nimbus feets directly connected to the ground plate.
My GGII was delivered with the BAZODRUT metal feets (like all GG1 too)
(if you are interested in this feets, BAZODRUT sells them in polish allegro)

The Bazodrut feets immediately improved the resolution, but I do not like the unstable placement of the GGII, due to the 3 metal balls.
The sound was now also a little bit to nervous, like using a cheap high resolution 101d tube...
So I added 3 unknown tuning feets under the 3 "half" Bazodrut feets, which are screwed to the ground plate.
This feets are similar to ebony wood blocks , but they are from a hybrid material.
Sonic Balance now was good, but still some resonances in the higher region were easy to identify.
The HRS M3x platform has a granite Topplate, so HRS s recommending the Nimbus feets not only to dampen the unit ground plate, but also to dampen the granite top plate of the M3x.
So I placed 3 of the Nimbus rubber discs (2 corner, one center) to the HRS M3x base and the resonances immediately disappeared.
after this, I repeated the tube rolling on another level
Still, my personal favorite so far is the Full Music 300b/ SE, but more tubes to come !
After the GGII experience today , I have to say, that the differences between some of the tubes were smaller, than the sonic differences between all the feets I tried.
Now I have the first time the feeling, that my investment in Koda Takumi K10 and CAT Statement amps was a very good one,
I never heard my Zingali speakers so good with digital frontend.
