| Can anyone explain in laymans terms why your gear sound better after warm up Temperature is a parameter that is fundamental to the physics of transistors, analog and digital integrated circuits, and other semiconductor devices. Consequently their behavior varies significantly as a function of temperature, and a competen... | |
| Anyone done A / B listening to compare vintage stereo receivers with today’s Amps/Preamps? I had commented on this question in the OP’s other recent thread. An excerpt from my comments, with a few words shown in brackets added by me now: Regarding comparisons of vintage vs. recent equipment, a seemingly obvious point but one which often... | |
| Watts and power @listening99, Ralph (@atmasphere) clearly interpreted your initial posts as referring to powering two speakers per channel simultaneously (i.e., a total of four speakers). However it now seems apparent that you would only be powering one Tekton sp... | |
| Most achingly-beautiful music I generally tend not to have much interest in unorthodox arrangements of familiar music, but I find the following arrangement for cello and piano of Puccini's famous aria "O Mio Babbino Caro," from his opera "Gianni Schicchi," to be quite beauti... | |
| Dazed & Confused The calculations I do for this purpose involve logarithms, which I do using a scientific calculator. But a simpler method, which yields reasonably good results, would be to start with the following calculator. It applies to box-type dynamic speake... | |
| Dazed & Confused Hi Paul,Happy New Year to you and yours as well.Both the Maggies and your present speakers have the same nominal impedance, into which the reworked amp will be able to supply 300 watts. All three Maggies have specified sensitivities that are 5 db... | |
| Power/Current: How much is realistic? Thanks Ralph (@Atmasphere). As you saw I factored in a loss of 3 db per doubling of distance, rather than the 6 db loss per doubling of distance that would apply to box-type speakers acting essentially as point sources. But even so, per your comme... | |
| Oppo 95: Low Output via Stereo RCAs ... Dynamic Range Control on While generally speaking I would expect having a DRC function turned on would increase perceived average volume, rather than decrease it, if you already haven't I think it would be worthwhile to see what happens to th... | |
| Power/Current: How much is realistic? @fruitloopsr, as you may realize lots of people successfully use power amplifiers having unregulated power supplies in conjunction with electrostatic speakers, the comments at Mr. Sanders’ website notwithstanding. Not to mention that there aren’t ... | |
| Power/Current: How much is realistic? @g_nakamoto, amplifier current ratings are among the most useless and misleading of specs. They usually represent how much current the amp can put into a dead short (i.e., zero ohms) for some unspecified miniscule fraction of a second. And in so... | |
| Power/Current: How much is realistic? To provide some perspective on this I did a calculation of maximum SPL (sound pressure level) at the listening position based on the following assumptions:-- Amplifier power 600 watts, corresponding to the upper limit of ML’s recommendation for th... | |
| Who else here is frugal? Hi Erik,I don't by any means consider myself to be frugal. But when I consider making a purchase involving what to me seems like a significant amount of money I try to make sure that it will provide me with commensurate value and commensurate e... | |
| Preamp connection to multiple powered subwoofers Thank you kindly, Chris (@cal3713 ).@kalali, the suggestion by @koestner of a buffer stage is an excellent one. A number of possibilities were discussed in the following thread, most notably IMO the iFi micro iTube2: https://forum.audiogon.com... | |
| Should the power be off every time changing cables? My practice has been to switch preamp selector to an unused input (if changing an IC), turn volume to zero, and activate muting on both preamp and amp. Less risky? Certainly! The only remaining risk that occurs to me is the one I described in the... | |
| Should the power be off every time changing cables? Miller’s suggestion about changing the preamp’s input selector switch while disconnecting RCA cables between the preamp and a source component will usually work ok, assuming that one remembers to do that.But if the source component is solid state ... |
