| Single way or multiway In contrast, some other well-known and equally respected speaker companies — such as Voxativ, Zu, Cube Audio, and Totem — use crossoverless designs. Who is right, and who is wrong? @bache There are two issues: Doppler Effect distortion and bea... | |
| Can single ended 211 or 212 amplifiers drive magnepan 20.7? interesting though that a 18w 845 amplifier cant drive it but a 25 watt pass labs can! both are class A @thegreenman The output impedance of the Pass Labs amp is much lower so 4 Ohms does not bother it. SETs on the other hand have a high output... | |
| Can single ended 211 or 212 amplifiers drive magnepan 20.7? Also, what do you think about parallel single ended amplifiers? eg 2 or 4 211 tubes per channel? I have heard some people say PSEs lose the magic as their power supply is shared/compromised compared to pure SETs. @thegreenman The problem with b... | |
| Can single ended 211 or 212 amplifiers drive magnepan 20.7? i know of those very rare stuff tt prob will, for example NAT audio large tube amps that output 120w class A @thegreenman The more power you try to get out of an SET design, the more trouble you have with bandwidth. This is true of PushPull tub... | |
| Can single ended 211 or 212 amplifiers drive magnepan 20.7? @thegreenman An SET based on a type 45 power tube might make about a Watt. Certainly not 7; if your amp really uses 45s and makes 7 Watts, its push-pull not SET. But to be clear on your original post, no SET made will drive Maggies. But FWIW the... | |
| Suggestions for a holographic preamp? @larsman One other tip when investigating preamps: The output impedance is usually specified at 1KHz. But if you want to have the preamp play bass as well as it does the midrange, the output impedance at 20Hz is nice to know too. If the preamp ... | |
| Suggestions for a holographic preamp? I don't know why he couldn't have put a 'Mute' button on there - all I really require is volume and mute. @larsman Many mute circuits have the potential to mess with the sound. Since your amp has a balanced input you might consider a balanced... | |
| Distortion Distortion Distortion @bjcatanzaro Distortion, for the most part, is the differences you hear between components. For example the smoother tonality often attributed to tube equipment is due to harmonic distortion. Our ears use higher ordered harmonics to sense sound p... | |
| Fritz carbon 7SE MK 2, Upgrade @robshaw We showed with the Fritz Carbon 7s last year at AXPONA. I found them quite transparent and neutral. We ran them with a sub crossed at about 55Hz. I run Carbon 6s in my bedroom system, using an amp of only 5 Watts/channel. It will be a har... | |
| Just got a new power amp @kijanki Right. (We introduced a class D amp of our own design about 4 years ago FWIW.) The question then becomes, in the context of this thread 'is it important?' WRT the thread title, it isn't. Ampex made a tape machine that was used for quite... | |
| Just got a new power amp One criteria of balanced output is lack of GND return current. @kijanki So if one side is at ground, but there is no ground return current to any other part of the amp, your criteria is satisfied? Or is the fact that the speaker circuit is not ... | |
| Just got a new power amp @kijanki Did you not mean to use 'S300' twice in the above post? | |
| Just got a new power amp @kijanki It looks like that amp is. But: I would not use a speaker terminal at ground as your definition, although our OTLs have both speaker terminals ungrounded and floating. Many ARC amplifiers do not have a grounded 'common' terminal; th... | |
| Phono Stage - The great analog tragedy @pani Just for the record (if you see what I did there) I was not making that claim. Just my means of reference, so as to avoid the 'fantasy' (as you put it) of live vs recorded. | |
| Class of operation for Tube Power Amps @westcoastaudiophile my comment was related to “real” class A design, not hybrid (pseudo ab) A2/A3 with enabling output tubes grid currents! Class A is defined simply as the output device does not go into cutoff at any point of the waveform,... |
