| What's the best EL34 amp besides 8b? Funny thing about the ST-70. Although it has a modest pedigree, it totally gave its competition a harsh run for the money- on paper it kept up with the Marantz 8B pretty easily. Its biggest weakness is actually its rectifier- it uses a single 5AR4... | |
| What speakers work best with electronic music? FWIW a speaker that is really good for classical music is also going to be good for rock or electronic music. Speakers don't care what you put through them!The same things that make a speaker good for electronic music (resolution, dynamic punch, b... | |
| Using high powered amp at low volumes power If you are running a high power amp at low power levels you will have a problem where the distortion and noise floor of the amplifier is actually higher than you may have expected. Nearly all high power push-pull amps, whether tube or solid state,... | |
| Snap, crackle, pop I rarely clean records unless they have obvious problems. For the most part I use a dust brush. Ticks and pops are not a problem despite that, although I am careful of the used LPs I buy, and try to take care of them by not handling the playing su... | |
| Ribbons or electrostatic speakers with SS Amp? FWIW Sound Lab redesigned their backpanel a little over a year ago making the speaker much easier to drive for tube and transistor amps alike. | |
| Snap, crackle, pop Some preamps will emphasize ticks and pops as well!Sometimes the loading on the phono cartridge can help too; a lot depends on what cartridge you have and the phono preamp. | |
| What speakers work best with electronic music? ^^ Actually it matters quite a lot. Electronic music can be quite demanding, on top of that it may come as a surprise but there is an analog/digital debate that is on-going in the electronic music community, and is why older analog synthesizers go... | |
| Tube Amp for Martin Logan Speakers However, it is important that the amplifier be stable operating into varying impedance loads: an ideally stable amplifier will typically be able to deliver nearly twice its rated 8 Ohm wattage into 4 Ohms, and should again increase into 2 Ohms. 'S... | |
| Tube Amp for Martin Logan Speakers Wrm57, the easiest rule of thumb is ask the designer what sort of amplifier they designed the speaker for. | |
| Tube Amp for Martin Logan Speakers :) Yes- damping factor is different from "output impedance" in that it gives you an idea of the servo performance of the circuit, it it has any. Unsound, what you see from that graph is the woofer driver in a box, combined with the impedance curve... | |
| Tube Amp for Martin Logan Speakers ^^ Ah- good. And we now also see why the Power Paradigm is still around some 60 years after it was supposed to be supplanted by the Voltage Paradigm: and that is because amplifiers operating under the Power Paradigm tend to make less odd ordered h... | |
| Tube Amp for Martin Logan Speakers Jandidden, keep in mind this thread is not about transistor amps. But more importantly you have to be careful here not not violate something called Kirchoff's Law.Actually you will find that such is impossible as it is a law of physics, and not pa... | |
| Tube Amp for Martin Logan Speakers With a measured damping factor of 4.7 and an output impedance of 1.5ohms it's closer to an 8ohm tap than a 4ohm tap.But all this can change with a bit more global feed back to raise the damping factor and lower the output impedance.George, this ma... | |
| Proper wiring of 4 8 ohm speakers and amp load.. ^^ If you are running 2 pair of speakers off of the amp the result will be 4 ohms total per channel and with a Parasound you should have no worries. You will get more power this way but you will also get more distortion (true of all amplifiers dri... | |
| Ssssh, is your tube preamp really that quiet? Why would a volume control (attenuator) after the gain stage affect the level of noise? Wouldn't that be true only of a volume control that is before the gain stage? Or have I somehow got this backwards in my head? I sense that I still have much t... |
