| Looking for my Final Pair!! "" Practical example s of Intermodulation Distortion (IMD) measurements Intermodulation distortion can also be used effectively to evaluate crossover designs. If a transducer is excited with a fixed low frequency test tone, for example near resona... | |
| QUESTION about Installing "Matched" Tubes Does that not indicate working tubes to begin with?Of course! But that is very different from saying that they won't arc right after shipping. Its like I said- if you make it two weeks after installation and you don't have a failure you'll proba... | |
| Broken ground phono connection You could replace the ground post with a binding post easily enough. | |
| QUESTION about Installing "Matched" Tubes The burning smell is likely either a cathode or screen resistor.I suspect this may not be the amp's fault- the tube itself might have simply arced. They are most likely to do that right after shipping. It does not matter that the tube is brand-new... | |
| 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... |
