| 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... | |
| Questions Regarding Installing a Wheaton Triplanar On A SOTA Cosmos Ralph, if memory serves my TP would not fit properly, which is to say so that the arm wand would not overhang the platter when at rest using a plinth where the Technics chassis sits above the plinth surface. Just looked at my Tri-Planar. If yo... | |
| A phono preamp with equalization selector @elliottbnewcombjr Use the 78 EQ when playing 78's; that and the right stylus should help with surface noise. There are not many LPs from the 1940s, but I suspect you would have to check on the back of the jacket to see what EQ was used. By 1956 ... | |
| A tube amp equivalent to ARC-80S or 160S? @nasaman There are now class D amps out there that challenge any tube amp made for smooth, relaxed character with detail, such that tube power amps are greatly threatened. | |
| Preamp advice @tubesound247 Your amp has balanced inputs so I would consider a balanced preamp as the amp itself will work better simply on that account. If you consider going that direction, there is a balanced line standard known as AES48. This standard help... | |
| A phono preamp with equalization selector @elliottbnewcombjr Nice piece! Take another look at that front panel. The EQ curves were very much standard by then. 'NAB' is a tape equalization. RIAA and the 'RCA Orthophonic' curves were pretty much the same thing; RIAA being for stereo. AES a... |
