New Speakers raise the bar
So, why is this relevant - because the ReQuests at least were very
revealing of the system driving them. Bill www.wbnoble.com There's no doubt that MLs are very revealing speakers, but not of pre-amps, amps or cables/interconnects. If two modern solid-state pre-amps (or amps for that matter) sounded different to you, it was likely because one was louder than the other, because basically, that's all the difference that there is between them (unless one or the other had some frequency response anomalies or one or the other power amp is not happy driving the highly reactive electrostatic speaker load). As far as cables/interconnects are concerned, $4000/meter Nordst interconnects and ones made with a couple of pieces of straightened-out coat hanger wire will sound identical, because electrically, they are identical. Because I can't seem to post directly here, and posting through the moderator causes my email to appear in the header, I'm going to be a very infrequent poster, but the above demands some kind of answer. ***** Maybe the moderator can remove my email address from the header when posting, in which case I'll contribute more (email on NG=spam, in my experience)**** 1. I have consitently found that +3dB of power is quite audible. I believe that the ML amp has a much better low end than the 1970s vintage kenwood it replaced, and probably a much higher slew rate. suffice it to say that using the SAME preamp, and the same speakers and the same CD with the same CD player and the same preamp and the same interconnects, and changing only the power amp, the difference was distinctly audible to me and to disinterested listeners in the house (yes, I took it home and tried it in my house). Neither was louder than the other. 2. I have never been able to hear a difference with speaker wires or power cords unless they are way undersized for the job, however the interconnect from the preamp to the power amp can make a huge difference. This should be obvious to all - after all the cable has impedance and that will affect the sound. If you cannot hear it, then so be it - I did extensive testing with cables I made, cables on loan from the stereo store, and anything else I could find. Quality, by which I mean sound that I prefered, did not correlate with price, though cheaper cables tended to sound worse, but it did vary dramatically as I changed the wire type and the way I used the various conductors in a multi-conductor cable. This effect was significant enough that my daughter walking through the room remarked "you must have changed the cables again, I don't like these new ones" - that's about as close to a double blind test as you will come in a home setting. The worst home made cables were made from twinax, the best were from dual TSP that was rated for overhead use. All cables were balanced (XLR). The best professional ones were Cardas (middle of the line) and Hovland. I bought from Hovland because they are local, friends, and the two were pretty much a dead heat as far as sound is concerned. 3. I was pretty systematic in my testing to configure my new system. I tried each piece alone with the "best in the store" and then integrated into my system before buying. since buying the stuff, I haven't changed anything, I'm happy enough. 4. here is line up of key equipment - speakers ReQuest, amplifier and electronics, Mark Levison 360S,332, 38S, TT - Fons, arm SME III, phone pre - homebrew op amp circuit, cd player - several - connected digitally except for Tascam, tape tanberg - you get the idea - the only interconnects that affect sound that I can hear are pre to power amp, and D/A to preamp. |

Neither was louder than the other. Ignoring, for the moment, that a 1970's Kenwood amplifier is NOT a modern amplifier, you might have a point. Bass performance is often a product of amplifier/speaker interaction. Such things as amp output impedance, and power supply design can affect how low frequencies are coupled to the speakers. But, OTOH, if you didn't perform a blind A-B test between the old Kenwood and the new ML where both were matched in volume to less than +/- 1dB using instruments, you are still dealing with sighted "expectation" results. 2. I have never been able to hear a difference with speaker wires or power cords unless they are way undersized for the job, however the interconnect from the preamp to the power amp can make a huge difference. This should be obvious to all - after all the cable has impedance and that will affect the sound. That's just the point. NO it doesn't. There are no characteristics of any conductor that could have the slightest effect on any signal from DC to 50 KHz or higher. No cable can produce enough capacitive or inductive reactance at those frequencies to impact any characteristic of the audio signal being carried. If you cannot hear it, then so be it - I did extensive testing with cables I made, cables on loan from the stereo store, and anything else I could find.

Probably gives you much pleasure. Enjoy. |
