“These (ACME 805) tubes are noticeably physically heavier and larger than the stock rebranded Psvane (HiFi series 845) tubes that Line Magnetic provides with their amplifiers. They are also strikingly beautiful pieces of hardware. “…….
“The ACME tubes sounded solid and transparent from the start and this only increased as they broke in over time. Break-in time is where I differ with some who may read this brief review. I did not notice drastic changes in sound after the first 15 to 20 hours of run-in. In fact, I felt that of all the power tubes I have tried in my amplifier E.g. Psvane HiFi series 805, Psvane 805A-T, TJ Full Music, and Sophia Electric, these (ACME 805) tubes changed the least over their recommended break-in period. They hold their bias perfectly. I have yet to adjust the bias up to this point in time. (Nearly two months of use). Every other power tube I’ve owned has had bias that drifted around a bit. Not these tubes.” …….
“Comparatively to the other tubes I’ve used, they have do have greater transparency, but where I felt these tubes excelled most in my system was when I pushed it hard and listened at high volume levels. The tubes held the sound together with great finesse and authority, never losing any control over the musical situation at hand. “……..
