There are at least 2 factors going with these discussions - the technical merits and the subjective listening (the perceptual listening).
I have heard pretty much everything in the last 35+ years when it comes to stuff sold to pros and home users. I started in the objective realm mainly focused on speakers and amplifiers that were well known in recording studios - and I brought it home to try. My first exposure to a SET amplifier was "pseudo blind" because the Audio Note amplifier was a large hulking box with no exposed tubes and I listened to that amplifier and thought it was big Krell-like SS behemoth - after my listening session with excellent deep bass and tight as a drum snappy bass crystal extended treble without being bright and a gorgeous vocal band I ask what a lot of people would ask - how much power does that sucker put out - he said 8 - "Wow" I said "800 Watts" - "no - 8. 8 watts."
That's how I first began giving some tube amps more tries - I had tried some PP tube amps in the 30-50 watt range and never much cared for them (Jolida and Antique Sound Labs mainly because those were the amps I could afford).
Over the years what I noticed was that whenever I was using Bryston Preamp and Power amps with ATC or PMC or Bryston etc speakers is that I was needing to put the volume "up" to make things out clearer and the bass often took on a washed out quality - To compensate for a lack of low level detail - I would always be compensating with the volume. Flipping over, in the same room, to something like the AN Meishu or OTO amps and AN speakers - I could hear everything several dB lower and without needing to turn up the volume. Voices didn't "warble" - the treble didn't possess the "hash" I was getting from the store's SS amplifiers. There were no audible hisss or hums at the listening position on digital (some on vinyl but that is there on the SS systems too).
One of the things I appreciated about that dealer was that they carried all kinds of gear - their theory being it is not their job to tell people what they should buy. You come in and listen - and if you like Bryston, Rotel, Anthem, Classe, Meridian, NAD, Arcam, Sim Audio, Cambridge Audio, Marantz, ARC, NAIM, McIntosh, Audio Note, Octave, Antique Sound Labs, Linn, Wyatech Labs, B&W, JBL, Cerwin Vega, Tannoy, Dynaudio, Dali, Monitor Audio, Sonus Faber, Reference 3a, KEF, Paradigm, DeVore, Quad, Magnepan, Finale - well they carried ALL OF THEM. The owner of the shop often brought in all kinds of brands beyond these if people were requesting them.
I like this approach - when they brought in Magnepan I asked one of the salesmen, Don, and he said "Yeah this is the second time we've carried Magnepan over the years - the worst speakers we've ever carried." Why carry something you hate? People like them.
Plus it takes all the pressure off the sales staff - they don't need to "push" or be assholes and tell customers "Boy you own crap - here buy what I sell it's much better" - nope all they did was listen - you want to try McIntosh and B&W because you read about it in Stereophile - right this way.
As The owner said - more than 90% of the people who walked in the door were presold via reviews and forums and some measurements they saw. So they carried those products. They don't have to do any work - most people don't trust dealers (I mean they're salesmen after all) so I get why most customers basically use the dealer as an order taker and to be there for customer support (when the world had that).
I get the "if it measures better, it will sound better" school of thought. I was in that school - but it just hasn't panned out when I do the listening. The AN system sounds "clearer" than the Bryston/PMC, Bricasti/ATC, Benchmark/Genelec set-ups when I have tried them - those systems sound brighter but that seems to me to be what passes for "accuracy" = The music is fuller and richer on the AN systems - the vocals are better defined the bass is full-bodied. As one reviewer described it - the pro system is like looking at a spectacular view through the "cleanest windows on the planet" - the AN System was like being outside on the deck experiencing that view firsthand - breathing in the air - and also breathing in some pollution that you don't breath in with the pro systems. I take the warts and all being on the deck experience that view over looking through the glass any day.
Again - a subjective response obviously but again it's an AN speaker thread and I am offering what most people who like this sound feel about the system.
I look back at some of the reviews over the years and I often think of this one as, yes, an almost religious experience (not being religious I can't say) but this is sort of it in audio. Holy Overthetop raving, Batman!
"I listened to one of Todd Garfinkle's M•A recordings, Sheila Jordon and Harve Swartz's "You Don't Know What Love Is." Wow.../.... the AN system gave me all of that—the room, the bass, and the woman, most of all the woman.../... My intellect tells me that there's no way a 25Wpc amplifier can control that, even on 95dB speakers, but the Audio Notes handled those passages better than any other system I'd heard at CES .../... Next came Nina Simone's "Little Girl Blue" and I was practically in tears. Everything just sounded so right. I had goosebumps .../... Forget best sound of show, for sheer emotional delivery, timbral clarity, dynamic agility, and, yes, the highest fidelity, the Audio Note system may have been the best hi-fi I have
ever heard .../... After the Audio Note demo. the rest was noise, so I quit on a winner. Not many people who come to Vegas can say that."
