| SUT - electrical theory and practical experience @rauliruegas You say that "the best SUT is no SUT at all." What structure(s) in your ideal phono stage replaces the gain that the SUT provides, and how is that necessarily better than an SUT? | |
| SUT - electrical theory and practical experience @lewm I was about to ask details about the transimpedance phono stages, such as exactly how the current is converted to voltage, and where / if a load is added, and how it automatically detects how to do the voltage conversion, but maybe that's ... | |
| SUT - electrical theory and practical experience @rauliruegas , Here’s my current assessment, which has been nicely summarized by @intactaudio : basically, the cartridge is naturally developed as a current generator, however for the past decades, phono stages were created to unnaturally transf... | |
| SUT - electrical theory and practical experience It seems like we maybe venturing slightly off topic with respect to SUT and SQ, but perhaps it is related, as SUT are magnetic-electrical devices, as are cartridges, which seems to be primarily magnetic and secondarily electrical devices (if elect... | |
| SUT - electrical theory and practical experience @rauliruegas You quote another post above: “A phono cartridge is a voltage generator (Vs)” To me, that sounds like a premise, and from my very limited knowledge base, it sounds like it could very well be a false premise, as phono cartridges gen... | |
| SUT - electrical theory and practical experience Perhaps this blurb from a manufacturer sums it up more concisely: they say the signal is tranferred "via electromagnetic induction" and creates "power transfer without distortion" Audio transformers are typically composed of copper wire windi... | |
| SUT - electrical theory and practical experience @lewm A brief internet search pulled up this basic, but informative article: Audio Transformers are electromagnetic devices that transmit and modify input electromagnetic signals into output signals via inductive coupling. They isolate an input... | |
| Liquid Stylus Cleaners Anecdotally, I had a stylus that had less than 200 hours on it, and I used to Onzow Zerodust regularly. One channel simply went out on the cartridge, and apparently somehow some wire in the left channel in the MC above the cantilever was simply b... | |
| Liquid Stylus Cleaners I've personally found that the Last stylus cleaner really does improve the tracking. I tried the Magic Eraser bit, but it left the stylus sounding flat, until I cleaned it with the Last stylus cleaner. | |
| SUT - electrical theory and practical experience @rauliruegas With your extensive experience and knowledge, I think you really could contribute positively to these audiogon threads, but somehow, I think you just do not comprehend the details of what is being discussed. No, I never said, nor is... | |
| Classical piano solo—Your one favorite performance and recording Yes, I would have to agree that Glenn Gould's recordings of Bach's Goldberg Variations must be among my favorite classical solo piano pieces, although he was more famous for his unique interpretations as opposed to the standard, establishment inte... | |
| SUT - electrical theory and practical experience @rauliruegas I think a course in English comprehension would benefit you immensely, and allow you to contribute more positively to these forum discussions: Firstly, the thread in April was a thread about phono stages for a particular turntable,... | |
| SUT - electrical theory and practical experience @atmasphere That's a very thorough, well-considered assessment of the advantages and disadvantages of SUT. Thanks for taking the time to share your knowledge with me / us! | |
| SUT - electrical theory and practical experience I’m not sure that I completely understand the matter, but it seems that there are two options in cartridge signal amplification in or before the phono stage: either 1. an SUT before the phono stage, or 2. a transistor in the phono stage. If that’... | |
| Which power cords have high resolutions and separation?? @timetraveler66 Where do you live? I’m sure a local will take you up on that. I would, if you lived near me. There was one blinded "test" done on another forum which supported your hypothesis. |
