| JJ preamp tubes - repeated problems Funny with the amount of tube amplifiers I see at shows I hardly see this as the product being in it’s twilight. JJ tubes maybe of questionable quality, or filaments maybe getting damaged in shipping? @audio_is_subjective I used that phrase bec... | |
| Microphonics, Feedback and Bob Carver @erik_squires The more feedback you have, the less the speaker can affect the amp. Feedback allows the amplifier to reject that which is not the signal and microphonic input from the speaker is an example of that. With more feedback also comes gre... | |
| Looking for 200 watt Amp to drive Dynaudio Heritage speakers To me, those impressions are mostly consistent with the current comment, “lack of soul or engagement." @mitch2 Right- but apparently, only holds true for those examples. They don't represent all class D amps any more than saying something lik... | |
| Looking for 200 watt Amp to drive Dynaudio Heritage speakers it seems that lack of soul or engagement is a common theme more so than other critiques. @marco1 I get that- I've experienced that myself. I think that comes from the designer not understanding that just because the amp is high efficiency that ... | |
| A persistent hummmm... The sound comes out of the speakers, AND if you put your ear to toe back left of the amp (where the toroidal transformer is), you can hear it buzzing there, too. @dtorc If I can point out something, it seems as if you are using hum and buzz i... | |
| Value of a preamp? Other than impedance matching and volume control? Preamps also provide any gain needed to drive the power amp. This is handy if you have a tape machine, tuner or phono section. In addition a good preamp will minimize or eliminate colorations c... | |
| Solid State Low powered Amplifiers @moose89 There are now class D amps that don’t take a back seat to tube amps for smoothness and detail in any way. If you get the right one you may find that not only have you solved the heat issue but you may find you don’t want to go back to the... | |
| JJ preamp tubes - repeated problems I'm curious to know if manufacturers test the tubes that they use in the amplifiers before they ship them out? Maybe they test fine and then go bad within a month. I'm very suspicious they don't bother testing their tubes. @emergingsoul They de... | |
| A persistent hummmm... @dtorc An electrician won't be able to help. He'll be out of his league trying to understand why the PS Audio regenerator is able to help. Since it helped only a bit, since you swapped tubes and also sent the unit back, its my surmise that Zesto ... | |
| Questions Regarding Installing a Wheaton Triplanar On A SOTA Cosmos And yet there are those devoted to mats that barely make contact with the LP, like the Resomat or certain cork mats. There’s no accounting for individual taste and rule making is futile. @lewm , @mijostyn was spot on with his comments about the... | |
| Help With New Preamp Decision Though I did not speak specifically with Aric about the AES48 standard, his website for the preamp does specifically say the balanced connections support AES48. @vthokie83 The inputs do but not the output. As far as I can make out the Coda sup... | |
| Looking for 200 watt Amp to drive Dynaudio Heritage speakers The comments regarding Class D lacking “soul” is what was most interesting to me as I very much feel the same way when comparing my new Class D amp to either the tube or Class AB Solid State amps I also currently use in my systems. @marco1 Tha... | |
| A persistent hummmm... @dtorc What happens when you short the input of the amp? Have you tested the input tubes? They are far more likely to cause any amp to hum, if the amp uses an AC filament connection (and most do). The test that the tubes need to pass in this r... | |
| Help With New Preamp Decision @vthokie83 Do you have a balanced input on your amps? FWIW, since this is likely all moot at this point, the MP-3 has a patented direct-coupled output which sets it apart from the others of your list and audition. If the Backert Labs was balance... | |
| Questions Regarding Installing a Wheaton Triplanar On A SOTA Cosmos If I am remembering the spatial relationships correctly, you would need a spacer wide enough to bring the base of the TP up to the level of the top of the square escutcheon that surrounds the platter (on Technics SP10 mk2, mk3, and R). @lewm T... |
