| solid state vs tubes Mapman, I am **not** talking about clipping, although it is true that in clipping, tube amps generally make less odd ordered harmonics than transistors do.What I am talking about is the fact that when you use feedback to control distortion, the pr... | |
| solid state vs tubes Minorl, not to put to fine a point on it but the idea of designing an amplifier to pass a signal without distortion is being heavily glossed over in your arguments, which, other than that, I find myself in agreement with.The problem lies with the ... | |
| does amp draw alot of power when volume is zero Y'know, if you are concerned about power usage, its really a good idea to turn the stuff off when you are not using it.I've been interested in solar power for a long time. I was shocked (hah! pun intended) to find out that the length of time it is... | |
| What amp/pre-amp would you buy for $12-15k? Finding a balanced tube preamp that will keep you in your budget is no problem. | |
| balanced connection, better than single ended? The raison d'etre of balanced line is to be able to use any balanced cable cable of any length (or cost) and have that cable have zero sonic artifact. So it does not matter the length (nor price); there is always an advantage to balanced lines.In ... | |
| All I want is The Truth, just gimme some truth... Anytime you use a buffer section between the volume control means (in this case, the use of 'means' refers to 'method') and the output, its really not fair to call it a passive, FWIW. This is because there is now active circuitry between the volum... | |
| solid state vs tubes MrT, there was a time when planars ruled the roost when it comes to resolution. That time has passed- there are a good number of cone systems now that easily compete with the best planars.However, my comments were more the point that if you had a ... | |
| solid state vs tubes Unsound, in this case Mr. Norber was telling me, as did the other manufacturers, that indeed their amps do sound better into higher impedances, despite making less power.The Mac autoformers are used to load the transistors at a lower impedance if ... | |
| solid state vs tubes Unsound, Paul Speltz who makes the ZEROs has a letter from Steve McCormick, in which Steve asserts that his amps, which have no problem with 4 ohms at all, sound better driving 4 ohms through the ZEROs.Upon hearing about this (which was about 2 ye... | |
| solid state vs tubes Aren't 4 ohm loads more problematic for tube amps in general? Isn't that part of teh [sic] reason why you advocate 8 ohm or higher speakers for use with your tube amps?This is true. The fact of the matter is that **all** amplifier technologies sou... | |
| solid state vs tubes Hello Unsound, you can see the issue in the curves of most semiconductors, perhaps easier when you compare input capacitance to current.At any rate, its easy enough to hear! Get a set of ZEROs and a 4 ohm speaker, listen to the difference when dri... | |
| SET Amp question If you have questions about how an SET or other 'current source' amplifier will drive a speaker, maybe this link will help in understanding what is going on:http://www.atma-sphere.com/papers/paradigm_paper2.html | |
| solid state vs tubes Magfan, here's a nice nutshell explanation that touches on this subject.That there are capacitive elements of semiconductors should not come as a surprise to anyone- most tuners these days do not rely on variable capacitors to tune the station, in... | |
| solid state vs tubes MrT, there may be another way to do this. The Quad has a low impedance at high frequencies and a lot of transistor amps will tend to make more power due to that, part of the reason why they sound bright on the ESLs and with less bass impact than m... | |
| The "great" sound of reel to reel explained People don't want neutral sound - just look at Audiogon posts how many people seek warm sounding gear or ask how to make sound warmer. One person started thread asking how to make sound warmer and less detailed (I advised blanket over speakers)Kij... |
