| 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... | |
| Why do tube amps often subjectively sound more powerful than SS ? @dynamiclinearity I'm going with 'a fair amount'. The venerable Dyanco ST70 has a damping factor of about 15. This does not change with a 4 Ohm load since you'd be using the 4 Ohm taps. It would be cut in half if you ran a 4 Ohm load on the 8 Oh... | |
| Spatial Audio Raven Preamp Sheesh. If our stuff had been damaging speakers we'd not have been in business very long. Odd how a solid state manufacturer could get away with that! | |
| 300b lovers @lynn_olson You might want to study the Wiggins Circlotron patent for the answer, or look at the setup/spec sheet of one of ElectroVoice's amps that used the Wiggins patent. Here is an example. I recently restored one of these (A20C model) that ... | |
| 300b lovers The Raven and Blackbird are non-feedback amplifiers, with the cathodes bypassed so local feedback does not apply, either. So there are no stability criteria or load stability issues. The distortion is simply the distortion of the matched pairs us... | |
| Spatial Audio Raven Preamp That’s the real difference between pro gear and audiophile equipment. The pro stuff is reliable, because it has to be. @lynn_olson If you're going to stay in business for the long haul producing high end audio products they have to be reliable ... | |
| Why do tube amps often subjectively sound more powerful than SS ? Tube amps also tend to boost the mid bass and mid range (from about 1 kHz to 2 kHz or ao) due to their low damping factor interacting with speaker impedance. @dynamiclinearity This is only true if the amp is unable to act as a Voltage source on... | |
| Tubes and less sensitive speakers Magnepans are typically very inefficient and require high current amps to get the best out of them. @jeffbij Just so you know, this statement is false. To understand why the first thing you need to know is how current plays out in a speaker... | |
| Tubes and less sensitive speakers I thought I heard Atmasphere amps can work well with Maggies but could be wrong. Worth checking or maybe @atmasphere can chime in. @soix We have a number of customers using our OTLs with Maggies. The smaller amps like the M-60 tend to be used... |
