| Why do we want to distortions? There are different types of feedback and I’m referring to traditional "loop" feedback. Degeneration is a bit different. But I think error correction is much better if that is possible in the design.Correction is good. Degeneration does not tend... | |
| Why do we want to distortions? Both Cheever, Pass and several others agree on that to much negative feedback create high order harmonics that we are very sensitive to. Cheever also discuss aural masking and the effect by adding such distortion to the playback system. But doe... | |
| Solid state amplifiers and sound stage, especially front to back "depth" That's at least how I remember him explaining it. And that seems to be exactly what Frank was saying he doesn't do. But I remain confused. @hilde45 All amps make distortion; if you understand how the ear interprets distortion than you don't have... | |
| Technics SL1000 MK3 (SP10 MK3) performance/value VS modern turntables? The best mat I ever heard was made by Warren Gehl of ARC (prior to his working with ARC). The last one I saw sold anywhere was $1700.00. They were heavy- about 5 pounds, owing to lead content. | |
| Nakamichi RX-505 and some nice tapes for it I would need a pro grade outboard Dolby S unit to experiment with it. I don't think I would want to go in this direction.@inna I don't blame you and I wouldn't either! Plus IIRC most outboard units are actually Dolby SR, which are meant for reel t... | |
| Running LOMC with MM (47K) loading 47 kohms is for moving magnets. I would use what is recommended by the cartridge manufacturer. My hana el calls for >400 ohms, I use 430. Not certain why you would exceed the value by 10's of thousands. 47K is the industry standard for all ca... | |
| Cons of using main XLR/Balanced outs for subwoofer? @milarep Yes to both questions.The 1Hz response will insure that you have no phase shift at all at 20Hz or even 16Hz. Phase shift in the bass will cause a lack of impact. The transformer rolling off at 10Hz will exhibit phase shift up to about 100... | |
| Class D amps that are superior to all or most? but many hear some thing not quite right with Class-D in the upper mids/highs with many speakers, and this is it’s Achilles heel.Technics (SE-R1/SU-R1000) claim to get rid of it by making the switching frequency 3 x higher, 1.5mhz, so that then... | |
| Solid state amplifiers and sound stage, especially front to back "depth" I guess I don't really know what that term can mean or how to interpret his commentsWell that makes two of us. If 'voicing' is trying to get the most linearity out of the circuit than we do that. But we're not listening to it when we do that- we'r... | |
| Solid state amplifiers and sound stage, especially front to back "depth" So far, if I'm paying attention, only the Sunfire 300 amp has been given props for an amazing soundstage.I've heard some class D amps that do very well too."I have no clue about "voicing" an amplifier. It is NOT a musical instrument. It is not ... | |
| Why do we want to distortions? what I am trying to understand is if the original recording is with euphonic distortions that are deemed as positive then don't we want the most transparent system to hear the original and How does tube euphonic distortions add a stage to... | |
| Class D amps that are superior to all or most? No, You didn't, here's what you said:However, the driven device forms part of the output filter and thus effects the frequency response.In this case its hard to construe the FR being different from the bandwidth because we are talking about the re... | |
| Why do we want to distortions? Is it related with the feedback , you are talking about ?Yes. | |
| Class D amps that are superior to all or most? There is little change for some products as I showed. For others there is a lot.It appears to me to come down to this. The reason is the filter isn't the only variable- class D amps vary quite a lot; some have zero feedback, others have feedback a... | |
| Solid state amplifiers and sound stage, especially front to back "depth" Then there is less well designed S.S. amplifiers on the market than we may think?IMO, yes.In solid state amps in particular this is all about how well their feedback system is designed. Most of the time though the problem is the amp simply lacks e... |
