| Mark Levinson ML-1 power supply Assuming that the description is accurate, "DC CABLE for Mark Levinson PLS-151 Preamplifier Power Supply," that is what you want. It wouldn't say "DC" if it was referring to the power cord to the wall.It's taken a lot of patience, but it sounds li... | |
| SET amp recommendation Hi Charles,An additional reason stems from the fact that if speaker impedance is higher, amplifier output impedance becomes a smaller fraction of speaker impedance. That will decrease the magnitude of frequency response variations that will result... | |
| SET amp recommendation 12-12-11: HermanAs long as you can live with the loss of power. I believe these calculations are correct....Not that it makes much difference, but the power loss will be a bit less than what you calculated. Since the output impedance of a SET amp ... | |
| Cable Settling??? 12-12-11: NeedfreestuffI have electrostatic speakers so it rules out the drivers loosening up. Thanks for the response. Not sure how relevant it may be, but as a point of information I'll mention that I've consistently noticed that if my Stax elec... | |
| Differential from source to pre but not amp? Balanced connections will considerably reduce susceptibility to ground loop issues and to noise pickup, regardless of whether the internal signal paths in the components are balanced or not. However, those benefits will be unnecessary in many setu... | |
| Cable Settling??? I am sure that putting hours on the new cables was the reason for most of my improvement ....What makes you sure of that? If it was a new amp, it could have been breaking in. If it was a used amp, its electrolytic capacitors might have been reform... | |
| Is this preamp mod to reduce gain advisable? RGS, thanks very much for the nice comments.The Rothwell's that Toby suggested could very well be a good solution, if what you want to accomplish is simply a reduction in overall system gain (so that you would be using the volume control at higher... | |
| will different lengths affect sound PS68, thanks very much. I should further clarify my earlier comment, however. As it appears you realize but others may not, I was not saying that the effects of a considerable difference in speaker cable lengths will necessarily be inaudible. I wa... | |
| Is this preamp mod to reduce gain advisable? 6db is not a large change in gain. I doubt that it would be worth the risks of problems arising, or effects on sonics or resale value.Regards,-- Al | |
| Hi Fi Dealers in NYC - where to find them? Try Take 5 Audio in New Haven, CT (near Yale University). I haven't been there in many years, but I dealt with them a lot during the 1990's and 1980's, and at that time, at least, they were exactly the kind of friendly and helpful dealer you are l... | |
| How Many Audiophiles Have Do You Know? How many audiophiles have you ever met ... by happenstance. Four. Two former EE co-workers (one of whom introduced me to it all, ca. 1979); a friend of a friend; and someone my wife used to work with.Regards,-- Al | |
| AC regenerator Thanks very much, Greg. Those are logical questions, and yes, a UPS is a form of power regenerator.However, for a number of reasons a conventional UPS would be unsuitable for use with an audio system. Those reasons include:1)Some of them, especial... | |
| will different lengths affect sound A corollary to Kijanki's good comment is that if the longer cable behaves in a neutral manner in a given system (which is dependent on the impedance characteristics of the speaker as well as on the cable characteristics), the shorter one will too!... | |
| Bandwidth question? Glai 12-06-11: In reviewing the measurement sections of stereophile, many amps with -3db at 100khz demonstrate subtle rounding of the edges when reproducing 10khz square waves. I don't listen to square wave so I don't know what that translate into... | |
| AC regenerator Charles is correct. A transformer does not regenerate power, which is not to say that it won't be a highly effective solution. As properly defined, a regenerator consists of an oscillator that generates a 60Hz sine wave (or 50Hz, depending on the ... |
