- Is this really the "high-end" forum??
-
- I'm not sure. Especially what I've been reading lately, like that
- stuff about antique electronics. Dick Pierce got most of it,
- but what he missed is very important.
-
- For example, the ideas that were expressed in the original
- article; like what some things were done certain ways, and how
- "weak" frequencies were amplified (or something) is absurd, and
- absolutely off the wall.
-
- Yes, it is a very romantic view of design, taken from a point
- of view of little no understanding of the subject. I guess it
- is an attempt to explain things that are beyond comprehension.
-
-
- The classic quote is (and I paraphrase) "Any sufficiently advanced
- technology is indistinguishable from MAGIC."
-
-
- While audio does at times appear to be like magic, and does
- embody elements which are magical, it is not magic. For example,
- the reason that a 2A3/6A3 triode power tube sounds "better" than
- an EL34 (as some think) is that it is a TRIODE. And, triodes have
- a distinctly different transfer curve than pentodes. Which is
- again very different from bipolar transistors.
-
- But, it can be demonstrated that very well designed, and built
- amplifers of any technology can sound very close, so as to be
- virtually impossible to tell apart.
-
- Before the rest of the crew flames out and goes nuts on me, this
- does not mean that all amplifiers sound the same. They do not.
-
- The reasons for the differences are manifold, and it would take to
- much space to educate the masses from this forum. But, amplifiers
- that are not clipped (at all) in actual service, with proper design
- and materials and speakers, etc., etc. don't sound particularly at all.
-
- The differences of things like oil filled caps and carbon resistors,
- compared to teflon and foil caps and bulk metal film resistors start
- to "look" and sound more important than the basic topology of "good"
- amplifier designs. Eh?
-
- The reasons that some systems sound NATURAL, not "squeezed" or
- some other phrases, are complex, and cannot be reduced to simple
- philosophies as suggested by dieter in Antique Audio Equipment.
-
- Or, put it another way, there are just as many horrible sounding
- systems today, as there were 30 years ago. "Squeezing" has nothing to
- do with it. Horns are not in and of themselves a panacea for anything.
- Efficiency itself does not imply fidelity or accuracy,nor does
- high power or "micro levels of distortion."
-
- In the end the goal is to recreate the closest approximation to a
- live event (the recorded "live" event) that you can, in your listening
- room. That means the the result must be able to "fool" your ears into
- believing that it is not an electronic/mechanical device operating.
-
- That is NATURAL sound, that is the goal of high-end. The only question
- for you, the audiophile, is which set of compromises are you willing
- to accept, and which are unacceptable. Then, select the gear that
- gives the appropriate results, without regard to philosophy or vintage.
-
- That's all folks!
