One Amp To ‘Rule’ Them All....

" There must be amplifiers in the world that work well with almost any speaker and are consistent competent performers that are also reasonably affordable. Defining some excellent examples and quite possibly some poor examples would help us all communicate better in terms of degrees about the qualities of any given amplifier in comparison to our benchmark amplifiers."

Hello brettmcee,

     Have you ever considered that an amp that works well with almost any speaker, is a consistent competent performer and is affordable may not even exist? 
     Even if one did exist, do you think the motley crew of knowledgeable and experienced audio junkies assembled here on Audiogon, burdened with their own firmly held audio dogmas like a gaggle of Taliban on an audio jihad, could possibly generally concur on exactly which amp that would be?
     Of course not.  Just as preposterous is expecting this unruly group of independent sonic beauty seekers to agree on benchmarks and a standard patois when discussing audio matters.  We're too busy tilting at windmills.
     I suggest your expressed goal of creating some kind of order and black and white certainty out of a chaotic shades of gray audio enthusiast diaspora will not end well and only result in frustration for all involved, myself included.

Best wishes,
   Tim

...not trying to frustrate anyone. I am very thankful for this community for all its hues and shades and even its dark corners. I love it even more for the brilliant, colorful characters you run into along the way. 

Home reproduction of audio is unlike any other pursuit. We never can go to a museum and see the way it was intended. We are responsible for reconstituting a recorded event as it suits us. And that is very, very unique in terms of 'art appreciation'.  

But it is 'frustration' that I am trying to get at, to chip away at. Gaining entry to high end audio is not easy or even friendly, sometimes it's not even fun. It's mad scientists practicing alchemy in dimmed rooms. Yet there is so much verifiable science involved. However we only apply the science as an initial hurdle and then sometimes when it suits us. Mainly we rely on 'synergies' and 'feels'. And I am fine with this for the most part because there is art in all of this as well.

I'm oddly mixed in a sense, having a Bachelor of Fine Arts and Masters of Science degrees and i do use computers (science/technology) to make animated features (art) all day long. Art and science certainly do mix and when mixed properly can make us 'feel'.

I started my deep dive into this stuff in 2009 and more intensely since 2015. I am still astonished everyday at how arbitrary and expensive it all is. I care about the health of this industry because I believe mental and spiritual improvement, (dare i say pure joy!) can be found in meditating on and experiencing excellent music as reproduced by our own hard-won 'spiritual machines'. I think more people should have access to quality audio reproduction and that it would benefit the planet.

To this end I am looking for a more direct road to audio Nirvana--not for myself but for others. I would like to make sure more people find easier entry into audiophile land. This is why I'd very much like all of you passionate audio nuts to help me define things a bit better. Lets figure out how to put some metrics to our subjective experiences. Lets see what synergies excite and concentrate certain qualities we love. 

I think it is worth while and should eventually create less frustration.

There aren't.

Generally speaking, transistor amps have a hard time sounding right on ESLs because the impedance curve of an ESL isn't a map of its efficiency unlike many box speakers. Part of this has to do with the simple fact that an ESL isn't in a box :)  As a result most solid state amps sound too bright on ESLs (and they already have a reputation of sounding too bright as it is).


If brightness and harshness is a problem for you, then you are more likely to gravitate towards tube amps. Tubes tend to make less of the higher ordered harmonics that the ear uses to sense sound pressure (and this is keenly sensitive to such harmonics, throw in the Fletcher-Munson curve and you have a problem). This is why tubes and tube amplifiers are still in production 60 years after being declared 'obsolete'. It just happens that tubes obey the rules of human hearing better than transistors.

You don't have to know anything technical here- all you have to know is that tubes are still around because people want them. Before you can have a 'benchmark' amplifier, you have to solve the distortion issues that separate tubes and transistors. My advice is don't hold your breath.

Hello brettmcee,
     
     I think you have good intentions and I agree with your thought that more people should have access to quality audio reproduction and that it might even benefit the planet.

    I certainly don't want to discourage you from gaining entry into high-end audio but I disagree with you that it's difficult and unfriendly.  I'm a bit confused about your perspective since you seem to believe gaining entry is akin to joining the Freemasons.  There are no secret handshakes or passwords...….. as far as you know.  Just a dumb joke.
     There's no permission required to join our lunatic fringe, it's just making a personal decision that you'd like to listen to your music of choice in your home reproduced at the highest quality possible with the only constraints being your knowledge, experience and budget. 

     For myself, it began with a love of music and subsequent general studies course in college called something like 'A Basic Understanding of Stereo Hi-Fi and Home Music Reproduction'.  If I recall correctly, I was just trying to satisfy the number of required credit hours of general studies courses for my Bachelors Degree and it sounded more interesting to me than Orienteering.  
However, this was actually a very good class that was very informative and sparked a lifelong interest in high quality audio and later video equipment.  The class had technical aspects of how music reproduction functioned electronically and mechanically along with explanations of the relevant standardized quality specifications. But it also had artistic aspects such as the various types of music and a good quality system (loaners from the local Stereo shop) setup in the classroom for demonstrations.
     This is how I 'gained access to quality audio reproduction' and began my lifelong journey in this hobby.  Similar classes, either in person or online, are one method more people could have access to quality audio reproduction.

     I'm generally willing to assist your efforts but I'm a bit fuzzy on the scope and specifics of what you're proposing. 
     Figuring out how to put some metrics to our subjective experiences sounds like part of a mission statement for a dedicated commission that I'm not sure a retired 60 yr old guy such as myself would be highly motivated or incentivized to join, given his numerous other opportunities to continue doing whatever the heck he felt like doing whenever the heck he felt like doing it.
