Swapped these into my PrimaLuna Prologue Classic in place of the stock, PrimaLuna EL 34s. A month into the swap, it’s been a significant upgrade as per my preferences — The EL34s were “very nice”, IMO, but these KT 77s add noticeably better dynamics...bass”punch” and other hard-to-describe improvements on top of everything the EL34s did right. The SQ has gone from “very nice” to “downright addictive”. There is a very small and not objectionable “forwardness” with this combo that I’ve noticed when listening to 1980s, mono Beatles CDs that were ripped to iTunes at the higher “CD” rez but this is the only time this tendency, which some reviews of the 77s on the web allude to, has been apparent to me. Highly recommended!

These are the best tubes in the EL34 family that I tried in my Primaluna Dialogue HP and I am not looking back. I tried the new EL34 Mullard for 350 hours and though they were better that the Primaluna stock, don't even come close to these KT77s. In the published specs the distortion is half of all the other EL34s, and in my system they run slightly cooler despite being biased at the same voltage and the background noise is imperceptible. The overall perception is of much better QC and build quality. Most importantly they sound exceptionally musical, detailed and balanced.

Does everything the Primaluna EL34 does, but with more punch in the bottom end. Great tube.
