Review: So far so good - Yeah it's only been an hour of testing and listening to music but hey I wanna get these thoughts down quick! First off, there is heaps of gain. Listening to this tube with my Project Horizon headphone amp and HD600 headphones, compared to other tubes I've been using I can definitely hear some gain buzz when the signal is off. But that doesn't take away from the sound. Couple notes: -Balance across the tonal spectrum. Throughout the range of sound including midrange being present, just as much as the highs. I can hear anything in particular that sticks out, maybe a 100 hour burn in will speak otherwise. -Soundstage isn't narrow but it isn't wide either. The music sounds right in between the ears and not too forward either. Almost like the sound is being presented in a half circle if that makes sense! -Kind of reminds me of a solid state signature. I'm actually hoping that with more burn in the detail will kick back a bit and warmth and smoothness set in, but I can't complain. If I can remember to do it I'll swing by here with an update on how things end up going after some good burn in time. Review: Mullard Tube - I got this to replace the stock tube of a channel strip, after the burn in process, the sound and tone of it was amazing!! these are the real deal, not a clone or generic copycat of the authentic version, outstanding value for the cost, highly recommended! ## Features - Tubes are handpicked from balanced inventory - Triodes are balanced within 3% for both gain and conductance - Perfect for phase inverter in a guitar amp or for use in Hi-Fi amps - Will have test readings written on the box - Large sound stage with excellent detail.
