| Does my Pass amp dislike my Meridian preamp? Bryoncunningham, try rotating the modules back into the preamp one at a time- let it run for 2 days each. If its one of those boards, you will know which one this way.If nothing happens, then the power supply possibility is increased and the idea ... | |
| how does current work in an amplifier? Unsound, most of the studies I am aware of in this area are so new that they are not published yet. However, one of the people conducting them is a Nobel Prize neuro-chemical scientist. I understand that High Emotion Audio has based a lot of their... | |
| new to tubes If the amplifier has an output impedance that is low enough, you can have variations in impedance that will not result in tonality issues with most tube amps, as long as the variations are not extreme. For example, a 4 ohm dip at a crossover frequ... | |
| Schroder sq and the new talea Cousinbillyl, seems like most of your questions are answered but the loading. I think you will find the loading to be not that critical. With LOMC cartridges, the inductance of the cartridge and the capacitance of the cable can form a tuned radio ... | |
| how does current work in an amplifier? Unsound, There has been testing in the laboratory that has quantified subjective listening objectively. What the testing has shown is that if the sound system violates human perceptual rules, the processing of the music moves from the limbic syste... | |
| how does current work in an amplifier? Unsound, certainly! I think we can add to that, heat, as well (although I know of transistor amps that run as hot as tubes). We are talking about a very traditional set of tradeoffs when these aspects are brought into the conversation: convenience... | |
| Solid State Power Amps That Sound Most Like Tubes? I'm continually surprised anyone would want tube maintenance issues on a tube piece that sounds so close to solid state.The trick is to run a tube preamp that sounds more like music that it does like transistors :) | |
| how does current work in an amplifier? A nice thing to do if you have Magnaplanars and tube amps is to back the amps up to the crossover and use a speaker cable that is as short as possible- 6 inches is a good length, and make the connections as tight as possible. This can have a profo... | |
| Does my Pass amp dislike my Meridian preamp? Bryoncunningham, the fact that it sounds better suggests that someone (not you) has not done their homework... I think your approach here is a good move.If it seems to be OK- you might have the cause narrowed to the computer and the power supply, ... | |
| cartridge loading If your preamp will not allow you to install the resistor, then you have to go with the switch positions they provide. Personally I prefer to do as much loading with resistors as I can, rather than capacitance. I worry about the capacitor and indu... | |
| ZU OMEN speakers 12ohms?? For the most part, one of our S-30 amplifiers and one of our preamps. For 99% of my listening, I can't clip the S-30 on that speaker. The meter barely moves at all. | |
| Solid State Power Amps That Sound Most Like Tubes? If you have ever see a price/performance curve, then you know that tubes and transistors are both mature technologies.Barring unseen innovation, your grandchildren will be talking about the same differences. Is 'same differences' an oxymoron? | |
| how does current work in an amplifier? The are some misconceptions about current. Here's the big one:http://www.atma-sphere.com/papers/myth.htmlOthers have already touched on the serious aspect of this, the idea that for 200 watts you need 7.07 amps (if a 4 ohm load) which is not reall... | |
| Does my Pass amp dislike my Meridian preamp? A loud pop can certainly do damage to the speakers, without necessarily damaging the amplifier.*All* the drivers damaged is a little weird- unless we are talking a smaller 2-way speaker. If it was heavily over-powered by one of these pops, it coul... | |
| cartridge loading If you have a Rega, the motor can be grounded to eliminate the so-called 'Grado hum'. A wire, which can be soldered to the body of the motor, is simply run to the base of the tone arm. This sorts out the hum; no idea why Rega does not install the ... |
