| Question for Atma-sphere, will expensive power cables improve your amplifiers? @westcoastaudiophile Yup! What you are describing is beyond most audiophiles. Many of them have a DVM though and it can show that there's something going on... | |
| Question for Atma-sphere, will expensive power cables improve your amplifiers? @westcoastaudiophile Usually the power transformer is one of the most expensive parts in any amp, unless SMPSs are used. Its very difficult to measure the RLC (especially the R) on a lot of power cords (you need a really good meter), but its fair... | |
| Why do tube amps often subjectively sound more powerful than SS ? Actually you don't need a degree to design tube amps. @dynamiclinearity That is certainly true. But it helps, especially if the amp in question has a feedback loop. Designing a good feedback loop is a bit less trivial if you want to get it righ... | |
| Question for Atma-sphere, will expensive power cables improve your amplifiers? claiming as thicker than 100ft house wiring 3ft PC will tangibly affect sound is not justified! @westcoastaudiophile As I explained earlier the wiring in the walls is far higher performance than most power cords so Voltage drops in it are less... | |
| Speaking of phono, line preamp and driver tubes, how close a match do we want ? @inna If the circuit is balanced differential you probably want the balance between internal sections of the tube. Check with the manufacturer on that one. 7% can be easy to meet depending on the tube otherwise. This will matter a lot less if the... | |
| Need to learn about Audio Research Class D is attractive, but of the ones I've heard were thin and edgy. @traudio That can happen if the power supply for the class D is under-built. FWIW there are class D amps now that challenge the best tube amps for smoothness and detail witho... | |
| Vinyl sounds better (shots fired) Vynil introduces a level of distortion that is pleasing to the ears of many, whereas other people prefer otherwise. @squared80 Actually vinyl has extremely low distortion- much lower than any of the 'tests' show. The reason is because of how mu... | |
| Spatial Audio Raven Preamp @lynn_olson Or a well-known American manufacturer that omitted, or forgot, the required 10~100 uF decoupling/stabilization capacitors for the multiple 3-pin voltage regulators, so they sang happily in the 10 MHz range. I've seen preamps and a... | |
| Why do tube amps often subjectively sound more powerful than SS ? Then why do almost all the damping factors measured by Streophile fall below 10 @dynamiclinearity I don't read Stereophile so I've no idea if this is actually true and if so, what amps to which you are referring. It might be a better question... | |
| Are EL34 based amps more musical than KT series based ? Or it's purely a matter of design? Then maybe I should upgrade output transformers in my VAC Avatar with custom ones ? This is a crazy idea, I think. @inna Could be... The output transformer is the most critical part of any tube amplifier. Its only crazy if you think so... You c... | |
| 300b lovers The even-order distortion of the driver section is cancelled in the primary of the interstage transformer, reducing driver distortion even further. @lynn_olson Actually if the circuit is fully balanced/differential from input to output, even or... | |
| Vinyl sounds better (shots fired) I recently read that almost every vinyl record since the early 1970s has been cut on a lathe that utilized a digital delay line for the source material. @dgd What you read was false. What you are talking about is a ’preview head’ which was used... | |
| How long do records last? Many are extreme high-end and the users aren't going out of their minds worrying about record wear and increased noise! @faustuss That's true. For years I did the same. I always use a carbon fibre dust brush before playing an LP side and I sus... | |
| How long do records last? I have LPs that were pressed in the early 1950s that still play fine. Any that I have that are that old I bought used. I think the conclusion of the video is spot on- that dust is really the big wear issue. | |
| Devore O/96 with high powered amplifiers @fsonicsmith @cold_pillow The DeVore can do bass nicely but its important to keep in mind the speaker is not designed for a tube amp with a higher damping factor. At shows DeVore is often seen using an SET with no feedback which has a lower damp... |
