| QUESTION about Installing "Matched" Tubes Yes | |
| Vfet / SIT Amplifiers What the VFETs have going for them is two things. The first is that its possible using them to design an amplifier that will make the lower ordered harmonics (2nd or 3rd) as the primary distortion component, in enough amplitude to mask the higher ... | |
| QUESTION about Installing "Matched" Tubes I go with the transconductance value if I can. Plate current works too but IME is less accurate.You'll have to bias the tubes up anyway, but if they all show the same transconductance values the bias setting will be nearly the same on all of them.... | |
| Looking for my Final Pair!! Sorry...VK80i is going back!Does it do this with nothing at all tied to its input? It might not be a malfunction so much as a ground loop or the like. | |
| 3D lifelike sound and impeccable measurements - mutually exclusive??? Measurements all aim at laboratory standards, royally ignoring the requirements of psychoacoustics. That is, we do not measure sound quality as perceived by the human brain. We measure reliability.I'm going to contest this. The measurements aren... | |
| Vfet / SIT Amplifiers Still better than almost anything on the market today, though.Ha! Not buying that for a second. Not saying its not nice though. | |
| 3D lifelike sound and impeccable measurements - mutually exclusive??? are there components (specifically amps/preamps and integrateds) are out there that combine great measurements and in your mind also have that organic immersive sound that really helps many of us get more emotionally involved in the music or ar... | |
| Class D for a Tube Lover There is no class d amp that will sound like a class A or tubed amp, sorry.The issue here is distortion- it is distortion that causes tube amps to sound 'warm' and 'lush' and its distortion that causes traditional solid state amps to sound 'bright... | |
| Looking for my Final Pair!! @m-db While I've had no desire to replace the speakers, that is because I've not heard anything better. But I did get them updated in that time- dual woofers, new crossover and field coil drivers.@roxy54 If you don't have some goat meat handy its ... | |
| Is the appeal to euphonic distortion learned? I will add that my experiences suggest that what one hears from the typical audience perspective can be quite different than what one hears from the performance band stand. That's certainly true! | |
| Is the appeal to euphonic distortion learned? As a personal aside, as a young man, for several years I attended musical events almost every night of the week, most of which were unamplified. To this day I find that while tube amps can sound pretty, they don’t sound like the live performan... | |
| Is the appeal to euphonic distortion learned? @mapman FWIW we are beta testing our class D amps right now. If we don't run into any emissions issues we expect they will begin production later this spring. | |
| Is the appeal to euphonic distortion learned? if the increased ratio of second and/or third order harmonics in tube equipment masks the higher order harmonics, are you also saying that the frequency response of tube amps in the highest audible frequencies is NOT lower than that of SS amps, bu... | |
| Shorting Amplifier Output I don't want to drop it off anywhere that isn't a preferred dealer or repair shop for Unison Research.You're not going to find one of those on every block of even in every town. Unless there is really something peculiar going on, any competent tec... | |
| Is the appeal to euphonic distortion learned? I don't think its learned.The presence of enough 2nd or 3rd (both are treated by the ear the same way) masks the presence of the higher ordered harmonics. This is common in tube equipment but not so much in solid state equipment, although Nelson P... |
