Stunning for Hifi
Beautiful in my KT88 based Hifi Amplifier.
very airy, transparent just as it should.
they are neutral and provide a very nice holographic effect.
nothing is exaggerated, the bass is precise and round, very dynamic. the highs are well cut without being tiring (the jj ecc83s gold pin are a tiny more aggressive in comparison)
the tone of voice is sublime.
lots of details and relief
thank you for these beautiful tubes which are worth our tesla e83cc that I had before and which cost me 5 times the price!
these tubes should still continue to open because they only have a few dozen hours so it promises;)
Andreas was really helpful in giving me advise for tubes
I needed new tubes for my Project Tube Box DS. Andreas was really helpful in giving me advise , as far as possible, by email.
These tubes were one of them and to be honest: They Rock!
Secret weapon in bass amps
If you're looking for more punch out of your bass amp, or if your guitar amp sounds like it has a blanket put over it, try this one.
Not the quietest preamp tube in the world, but the one I've heard with the most range.
