Short List of Amps I prefer over the Pass Labs XA25 or INT 25

erik_squires;
You seem to have gone off the deep end lately. 
You used to be a reasonably affable and knowledgeable bloke and now this? 
Do you really not comprehend the difference between MP3's shortcomings (and all of digital's) for the totally separate and distinct concept that Ralph is discussing? Are harmonic orders and truncated bits the same thing to your mind? 
To mine, there is one connection between Ralphs's post and digital and that is the limitations of modern measurements. Time and time again John Atkinson would measure a DAC (Benchmark being a prime example) or an amp (Benchmark again is a good example) and declare the measurements to be beyond reproach and often the reviewer coincidentally gave a rave review, but the buying public has disagreed. Certain highly esteemed writers/reviewers at S'Phile even disagreed. That is the only connection between Ralph's point and explanation and digital/MP3. 

And does your post above mean that you have only heard 8 brands of amplifier in your lifetime?
Implicitly equating the performance of ARC and Parasound is another gaffer.

It is clear from your starting sentence you are confusing me with some one else.  I won't be controlled by your disappointment, nor am I obliged to answer all of your obviously malformed inferences.

I've never made any such equation.  I mentioned that Ralph was using a concept known to me (please read the entire Wikipedia article here:

https://en.wikipedia.org/wiki/Sound_masking

)  and to ask him to clarify the leap he made which I could not follow. I did so in a respectful manner, and gave him the opportunity to come back and illustrate his point so I could get it.  Fortunately for me, he did:


@atmashpere

Essentially though the tubes have enough 2nd and 3rd harmonic distortion that those harmonics are able to mask the presence of the higher orders. So they **sound** to the human ear as if the higher orders are absent altogether. That is why they sound smoother.

Oh, my bad. I thought you were saying that the masking some how improved resolution. You are saying that masking reduces the perception of distortion. I was confused because earlier you mentioned that tubes have more detail, but the masking of distortion is unrelated to the perception of detail.

Thank you for the clarification.

Masking though, AFAIK has to do with closely spaced frequencies. Hard to mask higher order distortion, isn't it?

BTW, I like tubes a great deal. :) I'm not attacking them I just want to make sure I understand the arguments.

The explanations provided by Ralph above are exactly what I have been
reading about and find so interesting. Being afflicted with both Tinnitus
and Hyperacusis along with a measured 10k max hearing level, I 
am very sensitive to harsh, forward, bright sound.  Over 85db is uncomfortable
and when overexposed I require some time to pass before I want to hear any music even at lower levels. So that is me. Everyone hears things differently
so judge not lest ye be judged. I pass my finding as they relate to me.

My goal for is for music to move me, involve me, engage me.
"Magic" is the best term  I think.

If  "Neutral" and "Accurate" are your goals, the Lejonklou house sound
may be your ticket. Fredrik has a special Nothing Extra method of building amps
that allows you to hear lyrics you only guessed at before. 

Sometimes I wonder if all the terminology in use today-soundstage, airy, open, dark, etc was developed in an effort to classify sound that was actually unmoving
thus required further examination?
If sound does something to your brain that feels great then enjoyment is achieved.
Enough?

Yes. :-) The only judge of what you should spend your money on is ultimately the buyer. Neither I nor an oscilloscope nor countless reviewers have any right to interfere in that process.

Still, this is a discussion forum, and when asked to think about what we like and why we like it the technical differences in gear is a lot of fun to discuss.

Just like beer. We can talk about the brewing process and the hops added, which is fascinating, but ultimately the reason you end up in detox is up to you.
