| Something new. FWIW Dept.: the coupling between the platter surface and the base of the tonearm is one of the more important engineering aspects of a turntable. If they are not tightly coupled (and also as dead as possible) then the arm can move in a different p... | |
| Why Preamps Thump on Turn on @erik_squires Two ways of looking at that entitlement apparently đ | |
| Why Preamps Thump on Turn on @erik_squires Huh?? you have enough time to post that and then direct people to your site with this thread, yet not enough time to take down obvious misinformation? That'll take only slightly longer to sort out than it will for you to respond to ... | |
| Why are high efficiency speakers preferred for low volume listening? @immatthewj No, I was more suggesting the idea that if the speaker were 91 dB instead of 86, that the amplifier would be doing far less work. You could get the same sound pressure you do now with 1/4th the power. So your 50 Watts would be much clo... | |
| Why Preamps Thump on Turn on @erik_squires I should point out that in that article, the myth that a tube preamp produces a large Voltage spike is promoted. Thatâs usually not the case with them. Solid state has been around 60 years or so; I think weâd have been hearing about ... | |
| Why are high efficiency speakers preferred for low volume listening? @immatthewj IME its best to have the amplifier loafing for a living. They will produce the best sound they can that way and its always audible- smoother and more detailed (as well as measurably lower distortion, which is why 'smoother and more de... | |
| Why are high efficiency speakers preferred for low volume listening? I frequently see high efficiency speakers suggested for those who listen at "low levels." And is this another area that actually is "how easy the speaker is to drive (as related to its nominal impedance)" that is more important than the actual se... | |
| Solid State Power Amps 2Ă220W rms 8 Ohm, 2x 400W i 4 Ohm, all power is continuous rms measured at 0.01% thd+N. @gryphongryph This won't matter if distortion rises with frequency. It will cause harmonics in the region above the turnover frequency to be audible as har... | |
| 10dB resonant peak at 40Hz Your thoughts?  @mashif 'It depends'. If the subs are only active below 80Hz than interactions won't be a problem unless you place them side by side and operate them out of phase. If you have only one sub (and its only active below 80) then i... | |
| 10dB resonant peak at 40Hz Yes, DSP would do it. I'm not using a sub. @cdc You have a standing wave that is causing the peak. If you poke around, I think you'll find you also have some dips caused by the same issue. The best way to break up standing waves is by using su... | |
| Watts! How many do we need? is it watts that drive the speaker? (I know that if I put the + & - lead of my vm on the corresponding speaker posts. I get an AC volt reading which varies depending upon volume level.) But if it is watts that drive the speaker, and every wat... | |
| question about Balanced signals. @dukebdevil I got that. I was pointing out that in addition to the cables, there's a benefit in the electronics itself if fully differential and balanced. | |
| question about Balanced signals. @dukebdevil There are other advantages too- for example, differential amplifiers are more immune to power supply noise and they will have, in theory, a 6dB better noise figure than the same circuit executed single-ended. | |
| question about Balanced signals. @dukebdevil If there is a 6dB increase in gain by going balanced, then the equipment does not support the balanced standard (AES48). The reason this is important has to do with your opening question about the best interconnect for the money. If y... | |
| SS vs Tube Phono SUT/Output Stage which sound close to tubes without being too âwarmâ or ârolled offâ. @mikhailark Tubes, especially in a phono section, won't be 'rolled off'. The reason they seem to have less high frequency energy isn't due to a frequency response issue, its ... |
