| Audio Kinesis Swarm Subwoofer Awarded 2019 Golden Ear Award by Robert E. Greene @luisma31 The bottom octave is generally considered to be 20Hz to 40Hz, the second octave 40-80Hz and so on. 80Hz has a bit of a special meaning to subwoofers and the human ear because it is at about this frequency that bass appears omnidirection... | |
| At what price point do I run into diminishing returns on an MC Cartridge? The ability of the tone arm to properly track the cartridge is far more important than what cartridge you have! If anything this is the Achilles heel of LP playback as most people don't have their analog set up properly. | |
| Cartridge loading The Zu Denon is very much a "salt to taste" kind of cartridge when it comes to loading. When I used one it could indeed sound quite different when using 100/200/300/500/1000 ohms. And Zu will tell you there is no wrong answer here, just use w... | |
| Time to buy a class D amp? We're still working with prototypes. They have had 100 watts and double power into 4 ohms. Since last spring, they have had GaNFET output sections. We compare them directly against our tube OTLs as a reference. Mostly we've been sorting out layout... | |
| Installed bulk foil resistors in phono amp Any stopping resistors at the input of that preamp? | |
| Cartridge loading @stereo5 47K is the standard for phono cartridge loading. I am very happy at 1K ohms, I was just kind of wondering why.I explained why in my prior post. With a higher impedance load on the cartridge, the cantilever is more able to trace high frequ... | |
| Cartridge loading Cartridge loading is for the benefit of the phono section, not the cartridge!It prevents the inductance of the cartridge and the capacitance of the tone arm interconnect cable from creating a resonant circuit, by detuning it. The resonant circuit ... | |
| Eh hem!...Subwoofers... What do ya know? I’ve always been able to hear where they are . And thats not good .Then they are running higher than 80Hz.To hear sound below 30 you need way too much volume. That would disturb my neighbors below.And the peaks, valleys, and echo slap are too much... | |
| Time to buy a class D amp? Would you say there is inherent limitation in the phase shift that is a factor of the comparator speed, digital logic delays, and turn-off time of the FET? What do you think a practical limit is on that? That may put a practical limit of a few-... | |
| Adjusting tube bias... Its based on both the amplifier and the EL34 characteristics. For any EL34 going in that amp the bias setting will be the same. Be sure to check it one hour after warmup- you may find it higher. The correct bias setting will be what the reading is... | |
| Amplifier Hum - Only Amp Connected This sounds to me like a power supply problem such as a failing filter capacitor in the power supply. Such a part can indeed cause more hum in one channel than the other but the problem would be in both. Sometimes you might be able to get it to st... | |
| Time to buy a class D amp? I did not understand what kind of patent is this as class D amps are widely used for already more than a decade. 2 decades actually, but that does not mean that everything to be known about them is already known. The proof’s in the pudding when we... | |
| Budget Tube Amp (newbie) Read thru this thread and didn't see this anywhere so I thought I'd add my 2c. Old tube amps like the Dynaco generally sound more "syrupy" and warm than good modern tube power ampsIf properly refurbished this is not the case. | |
| Trying to find an amp that matches my tastes (aka death metal) Don't worry about what music you play. Electronics have no way of knowing the difference- what makes an amplifier good for classical music makes it good for metal too. | |
| Amplifier Hum - Only Amp Connected I will try the cheater plug this evening. Does it make sense that a ground loop would be worse in one channel?That hasn't been my experience but that does not mean it couldn't happen. |
