I'm a fan of GL KT88s and have used them for years here and there. However, the Gold Lion KT77s, at least in my single ended amp, are amazingly better sounding than any other tubes I've used in this amp, including KT120s, 88s, and 150s...I was surprised by this as I had tried a pair of JJ KT77s and they sounded not so good, but they're a completely different tube...now on my second pair of the GL KT77s, and man...a great tube.
Power Tubes Quicksilver Mid Mino
Just picked up a up Quicksilver Mid Mono along with 6 Mullard XF1 EL34’s. The tubestest surprisingly strong, but I want to extend thier life as long as possible and also try a different Tube Type. Any comments on the Gold Lion KT77 or KT66’s in the mid monos? I’m using a fairly efficient pair of Audio Note AN/Es, so I don’t think I need KT88’s or KT120’s. I’m running my exogal DAC striaghf into the amps. Great combo. Haven’t felt the need for an active pre. Thanks.
