| Is my preamp useless? So let us assume that I purchase this preamplifier. What happens to the power amplifier, sources and speaker cables? What about power cords? They also seem to have some degree of effect due to cable changes. At least in my system, the speaker cabl... | |
| Input sensitivity, Gain and Preamp matching Most SETs have low gain because they are intended to be used with high efficiency loudspeakers (usually 98 db or more). | |
| Electrostatic speakers and low volume resolution Since you have a solid state amp that does OK on the speaker right now my first inclination would be to simply go with the 2X multiplier tap, IOW 4 ohms. | |
| Describe ube sound vs solid state ^^ The nature of the dips should be examined. If at crossover points which is a common point of a dip, they will be of no consequence. The amplifier power will be signal dependent of course, and the output into 8 ohms will be 1/2 of its 4 ohm powe... | |
| Input sensitivity, Gain and Preamp matching One variable in this is the speaker sensitivity. I assume it must be fairly high because it must be able to produce satisfying output by the time the amp has reached about 20-25% of full power or about 4 watts. So in the average American home that... | |
| Is my preamp useless? I agree that I have not auditioned all the cables that are available. Will the manufacturer make a better cable next year - chances are most likely yes. Isn't advancement in technology supposed to do that? Nordost, Siltech, Shunyata, etc, all come... | |
| clipping and max rated watts/max volume I thought pre amps were built to max out the average amp right around half way on the dial. This has been my experience, I think. Except for my Oppo BDP95 at 2v out direct to my LSR&D monos with 2.4v in. But I can get the clipping indicators ... | |
| Electrostatic speakers and low volume resolution Listening is the best means. The use of the ZEROs should not represent a compromise to the tonality of the system. | |
| Is my preamp useless? I think you were generalizing that Actives were better than passives. I do not think I attacked your statement in any way. I was suggesting that we cannot make generalized statements. Isn't TVC a passive component?No worries- but apparently what y... | |
| Describe ube sound vs solid state ^Them it would appear that the Mac 30 is not capable of adapting to the variable impedance swings of typical loudspeakers without deviating from linear frequency response?No, not at all, unless the amp is set up on the wrong tap.If the speaker is ... | |
| clipping and max rated watts/max volume Clipping has very little to do with the volume control position and everything to do with how strong the signal is.So you can't rely on the position. If you hear the amp distorting, turn it down. | |
| Transformers humimg........again There are two things that cause transformers to hum, both on the AC line. This BTW is especially true if you have toroidal power transformers. The first is what is often called 'DC on the line' which is usually caused by a heater of some sort oper... | |
| Describe ube sound vs solid state ^^ If the impedance of the speaker is too low the output power of the amplifier will be lower and distortion higher. The lower impedance taps are provided to deal with this. It might interested you to know that the voltage rules that we are talkin... | |
| Electrostatic speakers and low volume resolution We do have customers that have had Martin Logans and our amps for extended periods- one guy still has the same speakers (CLS2s) and a set of MA-1s built in 1990. So you can use OTLs.Paul Speltz, who makes the ZEROs, has a letter from Steve McCormi... | |
| Describe ube sound vs solid state ^It works the same in both directions, and global feedback is not neccesarily a prerequisite.If the output impedance of the amp is low enough then feedback is not required. An example is the Ayre amplifier. An example of a tube amp that acts as a ... |
