Let me end the Premp/Amplifier sound debate ...

I'm old enough to remember Julian Hersch from Audio magazine and his very unscientific view that all amplifiers sounded the same once they met a certain threshold.  Now the site Audio Science Review pushes the same.

I call these views unscientific as some one with a little bit of an engineering background as well as data science and epidemiology.  I find both of these approaches limited, both in technology used and applied and by stretching the claims for measurements beyond their intention, design and proof of meaning.

Without getting too much into that, I have a very pragmatic point of view.  Listen to the following three amplifier brands:

  • Pass Labs
  • Luxman
  • Ayre

If you can't hear a difference, buy the cheapest amplifier you can.  You'll be just as happy.  However, if you can, you need to evaluate the value of the pleasure of the gear next to your pocket book and buy accordingly.  I don't think the claim that some gear is pure audio jewelry, like a fancy watch which doesn't tell better time but looks pretty.  I get that, and I've heard that.  However, rather than try to use a method from Socrates to debate an issue to the exact wrong conclusion, listen for yourself.

If you wonder if capacitors sound different, build a two way and experiment for yourself.  Doing this leaves you with a very very different perspective than those who haven't. You'll also, in both cases, learn about yourself.  Are you someone who can't hear a difference?  Are you some one who can? What if you are some one who can hear a difference and doesn't care?  That's fine.  Be true to yourself, but I find very little on earth less worthwhile than having arguments about measurements vs. sound quality and value. 

To your own self and your own ears be true.  And if that leads you to a crystal radio and piezo ear piece so be it.  In my own system, and with my own speakers I've reached these conclusions for myself and I have very little concern for those who want to argue against my experiences and choices.

Nice videos. I think I hear what I associate with tubes right at the start of one of those videos with the cymbal crash. I'm generally happier with the solid state sound but it'd be nice to be able to switch over to tubes with the flick of a switch if I felt in the mood.

If you doubt there are sonic differences between amplifiers, both preamps and power amps, A/B a few. If you cannot hear any differences you are probably not going to be affected by these choices. But to me, Amp and Preamp selection, next to speaker selection, make the the biggest difference in sound of any system I have ever heard. So no need to chase amps if you hear little or no differences. Geez, I wish it was that easy.

I don't remember what Julian Hirsch said about amplifiers but AudioScienceReview does not say that all amplifiers sound the same or that they measure the same.

... Any well sorted system is the result of multiple fine tuning steps extracting maximum synergy from its components. This is again totally ignored when putting individual units onto the ‘scientific’ test benches.

Yep, thank you. This thread or any other discussion that offers any type of "absolute" statements misses the fundamental point: human cognition is a subjective field and not objective science. Otherwise, let’s start arguing right now about the best novel book ever published... (I suspect, many here wouldn’t miss that opportunity, LOL)

I said this on my first post but... what they say is amps that measure similar numbers driven within their comfort zone would be hard if not impossible to tell apart in blind listening tests. That is not saying every amp sounds the same. I’ve heard differences in amps but I haven’t under  these basic conditions.
