| Atma-Sphere Class D… Amazing The fact still remains that Albertos amps use a switching device nobody else can source. Again, one that was designed for Audio, not for a battery charger or DC power supply. The only parameter that can make a GaNFET more suitable for audio is... | |
| Pass XP-17 and Hana ML loading question And what I meant by saying "terrible" was, sporrans and mid got clipped about 30% while bass got big but hollow and muddy no definition at al just slams of senseless sonic boom, and on top of that when record ended and I raised arm I heard harm... | |
| Something new. Ralph, are you therefore opposed to a table having separate tone arm pods? I think I am, as to me it seems logical. @bdp24 Arm pods being desperate from the plinth of the platter so coupling between the two isn't good. So this type of setup is ... | |
| Pass XP-17 and Hana ML loading question Yes, circuits are diametrically different that is a fact, but loading the cartridge should have same effect on cartridge performance , sound of it at least on the dynamic level should be similar to the loads on 15 at least in the characteristic o... | |
| 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 😉 | |
| 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. That’s usually not the case with them. Solid state has been around 60 years or so; I think we’d 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 2×220W 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... |
