Balancing "compelling sound" and euphonic sound


Has anyone else found the need to balance compelling aspects of sonics with forgiving/euphonic sound?

My examples here are headphone amps (but the points generalize to speaker amps).

I had a friend in the New Jersey Audiophile Society build me a custom 12AU7/FET headphone amp. I was amazed by its dynamics (micro and macro), it's musical detail and PRaT, expressive power. Very attention-grabbing sound.

I sold one of my other headphone amps at the time. Another one I had broke, so I ended up using this amp ever since then, about 8 years now. 

I massively improved my digital front end last year and although I found a much more dynamic and detailed sound, I had a lot of problems with overactive transients and this problem I have with certain sounds activating my tinnitus. I spent a lot of money trying to get something that had all the good qualities and none of the aggravating qualities.

Long story short, I tried a McIntosh headphone amp recently and all the "aggravating" factors disappeared. They were all in my 12AU7/FET amp! I didn't even realize that, and I could have solved my digital issues (which turned out not to be the digital) a lot quicker and cheaper if I had. 

At this point I realized I hadn't really ENJOYED my headphone system for a long time, and the McIntosh amp is more enjoyable. 

No it's not as dynamic or detailed or exciting, but it's the better option. And I used the word "euphonic" in the title, and it does seem that the Mac flatters certain low-quality recordings (such as YouTube classical music). 

I got tricked all those years ago because the 12AU7/FET amp was so engrossing. 

It seems that certain "attention-grabbing" qualifies of sound can also become fatiguing so they must be balanced with "pleasant" sound.

Many people have come to the same conclusion as you.  Sometimes it's called too detailed or too bright or ruthlessly revealing, but a lot of people find they prefer a more forgiving presentation.

There’s always that perfect balance to strive for, but it’s subjective, and every room and system is unique.  Just the right synergy of the right combination of components, room, and cables is all you need. wink  (which is always easier said than done!)

I’ve chased higher resolution for years, and sometimes it just reveals more issues to chase, but at some point within the last few years it all started to come together nicely to where the system sounds more like music with a sense of space and natural realism..  I never could afford expensive component changes, so went about refining what I had.  Unfortunately, there’s no single definitive path to achieving that perfect balance, in part because we all have a different definition of it. It can be a single component or room upgrade, or a slew of smaller things that close the gap.  It’s a puzzle, and a unique journey for all of us with an unknown destination.  That’s what keeps some of us chasing that nirvana for so long. 

I’m not sure what you mean by "overactive transients."

I understand the general issue you’re talking about, though. 

I do believe the euphonic qualities are not necessarily opposed to resolution and crisp dynamics. Dynamics are a function of the amp controlling the speakers, and euphonics and resolution have to do with the tonality, if I have that right. Some have found other tweeters to help bring both to the table.

I have speakers with a dome tweeter (Fritz, a bit more forgiving) but also a ribbon (Ascend) and AMT tweeter (DIY). When I use my tube or Pass XA25 amp with my DIY speakers (very sensitive) I get the euphonics and the resolution and the dynamics. Other speaker-amp combos change the dynamic PRAT a bit, but the happy tonal mix remains.

When I bring in a friends very powerful Class D amp, I get all the PRAT and dynamics I could hope for, but the brightness now takes over and I need to give the amp back to him. I am currently experimenting with the Benchmark AHB2 to see if it provides a happy middle ground. So far, I'm not sure. I'm missing the euphonics, that intimate midrange that makes me forget I'm listening to gear at all.

@hilde45 By overactive transients, I mean that transient attacks were a bit too powerful and slightly exaggerated. It's particularly noticeable in piano leading edges, which had a bit of a hard quality. This was more noticeable when I upgraded my digital front end, but turns out to have been mostly the 12AU7/FET amp doing it.

@magon 

Thanks. When you say transient attacks were a bit too powerful I assume they were too loud for the musical context, including the piano passages. That helps a lot and I found that happening with a Class D amp I was testing out.

It sounds like you are noticing the same thing, that an amp can have that excitement, dynamics, etc. and yet have something in the sound that is unattractive. In my case, it was simply lowering enjoyment. I knew I was listening less to my system since getting that amp, but I figured I had other interests. Now I realize it was the amp all along. When I was noticing sound qualities to check boxes, it seemed to check them all. But the enjoyment wasn't there.

(And I don't mean it was cold or lacking musicality. It was amazing in many ways including musicality. It just had this "wart.")

I've had the impression that Benchmark is an "engineer's brand," focused on good measurements. I haven't heard their stuff, but I'm suspicious when equipment is engineered for measurements - maybe the musicality isn't there.
