| Need upgrade info for my Atma-Sphere Novacron Amps Cabeau, I'm guessing that you had the old kit assembly instructions, and they have never been online! We still have that stuff on file- it never made it to electronic format. Email me and we can sort this stuff out. There are a few tweaks that are... | |
| Can fun be used to describe equipment? I thought Duke's (Audiokinesis) new speaker was a lot of fun. IMO, he had a goal for performance and price and knocked it out of the ballpark. Right after the show ended he moved the speakers down the hall to a bigger room, and I got to hear them ... | |
| Negative Feedback a deal killer? Magfan, to answer your question, in a power amplifier of conventional design (not class D IOW) the problem you face if you use local feedback as opposed to global is the issue of gain. IOW if the stage that the feedback is around does not have a l... | |
| Negative Feedback a deal killer? The faster the amplifier, the less this is a problem! However, faster is not the same as 'real time'. I would say that this is in the realm of 'progress' where we have an improvement over something that was done 15 or 30 years ago.I think you can ... | |
| Negative Feedback a deal killer? If the amplifier has other design considerations, it will not need to have feedback to be low distortion. For example, a fully-differential amplifier will have even-order cancellation at each stage in the amp, so it will, without feedback, generat... | |
| solid state vs tubes Tmsorosk, this one was a little different as the OP wants a transistor amp that does what a tube amp does, without the hassle of tubes, if I read things right. There was a discussion of some differences between the technologies that you don't see ... | |
| The best tweeter design Weseixas, Blkadr, yes the HEA tweeter *does* look like the old Linaeum, but if you have a closer look they have little in common except that they are both tweeters. The HEA tweeter is sort of like a ribbon tweeter in a horn configuration- That dia... | |
| The best tweeter design So far one of the best I have seen is the new tweeter made by High Emotion Audio http://www.highemotionaudio.com.It is high efficiency, very fast but smooth without brightness and extremely wide dispersion angles (120 degrees). It is also rear-fir... | |
| solid state vs tubes Mapman, I agree, the problem is this: distortion, in the form of exaggerated 5th, 7th and 9th harmonics (compared to the original sound) **masquerades** as 'dynamics'.A simple way to tell that a system is lacking this distortion is that you can't ... | |
| good tube amp match for maggie 1.7's? Driving Magnaplanars is easy. If there are any doubts about a tube amp being able to do it, a set of ZEROs http://www.zeroimpedance.com to help out will do the trick. | |
| solid state vs tubes If you perceive the peaks as less loud because that is how people hear, that would seem to infer that the dynamic range is affected, at least as perceived, since the peaks do not seem as loud anymore, just as those nasty loudness cues due to negat... | |
| Can I ground my preamp? The preamp, being the heart of the system, should be grounded. The amps, for safety reasons, should be too, but for audio reasons (ground loop prevention) they should not. If the amps hum when grounded through the AC cords, it indicates that the m... | |
| balanced connection, better than single ended? Roscoeiii, I'm not sure I understand your question... I have used transformers at the output of single-ended preamps to enable them to drive very long cables, which by default have to be balanced. You can't do it with a simple adapter though, you ... | |
| solid state vs tubes Soft clipping means that dynamic range is restricted to some extent as I understand. That means loudness cues are reduced relatively, all other things aside, as well, right?What I was talking about is the types of distortions made by tubes and tra... | |
| balanced connection, better than single ended? do you imply that any sonic effect of cable capacitance, inductance and other electrical characteristics effecting the single ended cable sound - vanish? Gone? Diminished?Yes, either gone entirely or dramatically diminished. IME 'gone' is a lot cl... |
