| Power output of tube amps compared to solid states Marakanetz, not to be on your case or anything but while we do go for as much performance as possible at the same time we take advantage of the vintage look to keep the overall cost down, making our amps affordable against similarly-powered tube a... | |
| Power output of tube amps compared to solid states Sorry, Marakanetz, that explanation is not correct. First off, not all tube amps have output transformers. Mlsstl put his finger on the issue- odd ordered harmonics.Smooth clipping is less odd-orders. Music is a very transient sort of waveform- wh... | |
| Designer Hall of Fame Beerdraft, no, we don't make transistor amps. We're known for making OTLs but we've been in business nearly 34 years and in that time seen a lot of OTL manufacturers come and go. One of the signs that an OTL manufacturer is going to go out of busi... | |
| current versus watts Dob, yes, the transient time, propagation delay, plays a huge role in the effectiveness of global loop feedback. I am not sure exactly how fast an amp has to be though; even the fastest amps I have seen seem to have problems when feedback is appli... | |
| Empire 208 turntable When we made our new plinth the difference was immediately audible. Its machined out of solid aluminum and fits all the old parts except the arm. You can treat the old plinth with damping materials, but the stiffer you can make the coupling from t... | |
| Are linear tracking arms better than pivoted arms? Pgtaylor, its the arm tube. It has a mid-frequency resonance and is poorly controlled by the materials within. That's where the Graham and the Triplanar take it to task.The Sayles arm looks brilliant. Now can we have a version that puts the bearin... | |
| Designer Hall of Fame Beerdraft, I agree with you that some manufacturers do do that. I'm pretty sure the rest of that is apocryphal. We heard his amps almost right away... | |
| Amp/ preamp for electostatics and why Ikonetic, I just search on 'atma', that's the easiest. FWIW the autoformers will have less in your path than a conventional output transformer-coupled amp will and there is a version that essentially replaces your speaker cables. | |
| What tubes for sibilant SET Triode amp Some people have quiet environments and their rooms are lively at the same time; I can see how that can work. Tfkaudio's suggestions sound like a very good place to start. Like I said before, sibilance is something SETs are not known for, and a bi... | |
| What tubes for sibilant SET Triode amp So your amps make about 12-15 watts- that means the Gallos have to be about 102 db to really take advantage of the amplifier's capabilities, and I don't think they are anywhere near that! So my guess is you are pushing the amp too hard to let it s... | |
| current versus watts Hi Dob, I agree keeping distortion down is important. Distortion can hide detail. A lot of designers use global negative feedback to reduce distortion though, and this technique often results in subtle enhancement of odd ordered harmonics, specifi... | |
| current versus watts When we are talking 'best', IMO power doubling has nothing to do with it; none of the 'best' amps I have heard have that capability.I feel that the specs have no meaning if the resulting amp is unlistenable. IOW our ears are more important than th... | |
| What is meant by a "fast" pre amp Agreed- 'fast' by itself would strike me as being a coloration. 'Fast' with a host of other aspects (detailed, transparent, **relaxed**, wide bandwidth), no worries. | |
| Amp/ preamp for electostatics and why Rrog, do you mean you are surprised that I recommended one of our used amps rather than a new one? Its true that I avoid direct recommendation of our products, even when I think the recommendation is warranted. However ESLs together with OTLs have... | |
| Empire 208 turntable IMO the 208 is the one to mess with because you can put a modern arm on it. We did so much tweaking to it we finally even made a new plinth for ithttp://www.atma-sphere.com/products/208.htmlIf you want a simple effective tweak, get rid of the 45 r... |
