| Gauging interest in a 2008 Continuum Caliburn As with everything, there will be an interest at the right price. There have been at least two different Caliburns listed on this site for sale in the past 1 year, and neither have sold. There's probably a reason for that: technology may have m... | |
| Want to add vinyl to my system. Of course, I'm biased, and without extensive experience, but I played my Rega P8 with various cartridges through a Manley Steelhead phono stage / buffer pre-amplifier, which I ran directly into my amplifiers. It sounded very good to my ears, but ... | |
| SUT - electrical theory and practical experience I think that @pindac has the correct approach: when children are misbehaving in order to get attention, it's best to ignore them; this approach is colloquially known as "don't feed the trolls" on the internet. | |
| SUT - electrical theory and practical experience Well, my overall assessment is that there are several commenters who always have a positive contribution to just about every thread that they participate in: @atmasphere @antinn almost always have significantly positive contributions to every... | |
| SUT - electrical theory and practical experience @holmz While I'm not certain, I think @dover may be referring to the reaction of the square wave to various loading, resistance, and capacitance properties, when dealing with SUT, which is found on that same Rothwell Audio Products site: " ... | |
| SUT - electrical theory and practical experience For those who don’t mind clicking links, and are interested in reading more, here is the link to the informative, educational page from Rothwell Audio Products, and they do mention use of different materials, such as copper vs silver somewhere on ... | |
| SUT - electrical theory and practical experience As @intactaudio points out, loading is another aspect of the SUT, and this is where, based on my limited reading, things seem to start to get complicated. Here is what Rothwell Audio's website says about transformer loading: "transformer loading... | |
| SUT - electrical theory and practical experience ….but, Rothwell Audio Products explanations also go into further detail in the next section, which would definitely imply caution against SUT use in a current based phono stage, due to geometrically increasing impedance: ”the transformer turns ra... | |
| SUT - electrical theory and practical experience @pindac Yes, Rothwell Audio website seemingly very clearly and concisely explains even the basics of audio, as evinced by the next paragraph on impedance loading of cartridges, which can be applied to any component matching: ”cartridge loading ... | |
| SUT - electrical theory and practical experience One user recommended a particular search, and it supplied the following website, which I found very informative. Here is a copy from the first two paragraphs from a transformer manufacturer, Rothwell Audio Products: “the cartridge operating prin... | |
| SUT - electrical theory and practical experience @holmz Thanks for sharing those details. I don’t know the details of how a FET works, but I’m sure it has its deficiencies, as does the SUT. I think that 0.00003 seconds (1/c) is essentially instantaneous to the human mind and ear….just ask th... | |
| SUT - electrical theory and practical experience @rauliruegas Your latter post about preferring an integrated "phonolinestage" over separate phono and pre-amplifier would also logically favor an integrated pre-amplifier / amplifier over separate components, so I'm not so sure that your ideal p... | |
| SUT - electrical theory and practical experience @rauliruegas Thanks for the detailed response. So, just to clarify, you are most concerned about the bandwidth limitations in a SUT. I could agree with that; however, I'm not certain that actual signal degradation is any better or worse in a t... | |
| SUT - electrical theory and practical experience @rauliruegas In that post that you refer to, you mention: "A SUT is not a passive device because any audio signal passing trhough those transformers makes that the " hundreds " of meters on each transformer react to that signal and starts the d... | |
| 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? |
