| Why do some manufacturers reverse preamp polarity in the first place? Over the years I find bass is the greatest offender. I hear it more in the brass instruments. | |
| Step down transformers detrimental to SQ? Its also possible to step down the AC voltage by doing an old DIYer trick which is to buck the AC line voltage. This is done with a smaller transformer that has a secondary rated for the current you need (50% more than the fuse rating is good) and... | |
| Why do some manufacturers reverse preamp polarity in the first place? We've had a polarity switch on our preamps since their inception. Changing speaker cables around is a real pain! | |
| Question on tube placement... IME its best to put the best tubes as early in the signal chain as possible. Of course this asks the question 'which tube is best?' and if you are messing with NOS tubes that can be tricky to answer- some tubes work better in certain situations th... | |
| Why do some manufacturers reverse preamp polarity in the first place? Its rare that the absolute polarity is audible- you need a purist recording that is done with only two mics. 50% of all recordings are in reverse polarity to begin with, since the recording industry does not pay any attention to this issue. | |
| The Science of Vinyl/Analog Setups Where was I? Oh yeah, man-made. There is one thing man has made that breaks this rule. And its not tubes, wire, speaker cones or cabinets, and it certainly isn't records. Its CDs. And yes, digital distortion levels are lower. Absolutely. But we... | |
| a dilemma for cartridge/phono stage combination in several places i read that low output mc are generally better in sound then high output .Low output cartridges generally have more bandwidth.tried to find out prices of Jensen sut’s.do you mean one of those?https://www.cs1.net/products/jensen_t... | |
| tube pre amp or tube amp SS power does develop better bass than will tubes. This is not universal!That depends a lot on the relationship that the speaker has with the amplifier. If the speaker is easy for the amp to drive, a tube amp may well make better bass. An example ... | |
| a dilemma for cartridge/phono stage combination If you like your phono preamp rather than replace it I would get a Step Up Transformer (SUT) **if** you decide on a low output cartridge. The SUT will have to be properly loaded (which is usually a resistor-capacitor combination) depending on the ... | |
| Preamps with separate L/R volume controls Just trying to understand why limit the options if a balance control serves the same purpose. Having Gain Trim controls allows you to not only set the balance but also the overall gain of the line section. An example might be if you have a digital... | |
| Big question tube phono pre amp or tube pre amp w/phono? Do you have to have the DAC built-in? That's really going to limit the field... | |
| Tube amplifier suggestion for 101 dB speakers Yes I'd like to keep the Classé Sigma pre because it has all the features I need in a preamp. But presently having no experience with tubes, I do not know which mix [tube pre + ss amp] or [ss preamp + tube amp] has more effect on driving my spe... | |
| HELP!!! I need a “GOOD-CHEAP” preamp solution??? If you are just getting a line stage, get one that uses 6SN7s. The worst of the 6SN7s are about where the best of miniature tubes are sound-wise and it just gets better from there. | |
| Tube amplifier suggestion for 101 dB speakers Even if your speaker has a high efficiency, I do not recommend small power SET amplifier to drive two 15 inch drivers.I can't imagine why.My speakers are 98 dB with dual woofers. My preamp has a fair amount of output and in a pinch, I can use it t... | |
| New Member And few questions on First Tube Amp. Well every one I want to thank all who have helped.. Not in tube amp purchasing but those of you who responded to tinnitus ..If your moniker is an indication- I hope you wear earplugs when riding. I found that earplugs were not enough unless I was... |
