Well, the rolling begins ....
Tried some Siemens 7308s/CCa's, wow, .... I heard details I aint never heard before.
At first, they even sounded a bit unhinged/erratic for the few 2-3 hours, then seemed to settle in a bit. Took me some getting used to such detailed sound.
I guess the tubes had about 500 hours on them already, so broken in. But my ears were not broken in for this tube ....
And by unhinged, i mean whole band crescendos and solos, like guitar and sax. I swear, one guitar solo flew rightoff the left side of the stage!! Along with the guitarist!!
But man, those things reveal detail like no other. Even the R/L is so tight and accurate, its a bit unnerving with the Th900s.
Then I put the Siemens CCa's in my home stereo tube preAmp- seemed to sound more cohesive with speakers. The low end in
particular, quit a bit of decay on the bass, almost sounded like a "gong" (remember the Gong Show? lol)
Also got two Amperex 7308s i just received: on the HPs, the soundstage and R/L integrate like no other.
I mean, the 900s are already known for their soundstage, but the 7308s took it to a new level. Very musical and listenable, thougha the overall sound was a bit "light" compared to the Siemens.
But I'm just breaking them in, so we will see ....
Others experiences with these tubes?
