| Amp Specs esp. DampFactor : Citation, Adcom, etc. Some folks are passionately against using specs in judging equipment and others, albeit a smaller group IMO, are just a passionate that specs/performance should be measurable. Personally, I'm a military historian and tend to be analytical, so whil... | |
| is a step up/down electric transformer bad ? T_bone, your first example is what I was talking about, not the latter. 100W on a 1500W transformer is no worries.The formula for calculating the distortion at the output of the transformer is E = I x Z (if this seems similar to Ohm's law to you i... | |
| Vinyl presses on last leg? Pressing limitations st The Neumann isn't the only cutter out there by any means. There are a lot of Westerex 3D units, and if you know history, these are the ones that did the old RCAs and Mercuries. The Westerex still has good support. The real problem is the laquers. ... | |
| Can fun be used to describe equipment? Duke's speakers seem like the kind that set up fairly easily, FWIW. I have a set of Classic Audio Loudspeakers that seem to set up easily as well. I have them 6 inches from the rear wall, and no worries with the soundstage and the like... | |
| Best Balanced Tube Amp To Pair With Meridian G02? Just FWIW... It is an easy task to add a true balanced connection to nearly any amplifier. Now before y'all go off on me, keep in mind that I am associated with balanced amps and preamps, and that I have good reason for saying what I did.I am **no... | |
| is a step up/down electric transformer bad ? The rule of thumb is that the transformer be rated for double the maximum that you are going to ask of it. If you go above that, the transformer will add distortion to the AC line and the results are both audible and measurable! and not good. | |
| 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 ... |
