So are you saying that you agree with the previous poster that there is no truth? Or are you saying that you have the truth, and that vinyl and tube amps are "by definition, not high fidelity?" Because clearly, there are some people who believe that vinyl and tube amps reproduce the sound of music better than CDs and solid state, and there are others who believe otherwise.
There is an objective truth, but the issue is that sometimes (often?) people confuse their subjective opinion as objective truth.
Vinyl is objectively inferior to CDs, and more recently even higher resolution file formats. This is objectively, scientifically true. But that is completely separate from people's subjective enjoy of the format. Of course, there are many people who prefer the sound of vinyl for various reasons - stating it is "warmer" (which is often the result of the very inherit distortion of the format, rather than it being superior), more "organic" (often because of poor modern day mixing and recording practices eg the loudness war - again nothing to do with the superiority of the format).
For tube amps, they are cost performance poor because it is incredibly difficult to make a linear tube amp compared to a solid state amp. Also tubes tends to have higher harmonic distortions then solid state amps. These are the objective facts. Again, nothing to do with people's subjective preferences for their sound quality.
Note that if you use the very narrow high fidelity definition you have stated ("faithful reproduction of sound"), then both vinyl and tubes actually fails to measure up against newer technology and gear, especially in the price/performance area. Yet, many of the audiophile community will not give up these gears until you prey them from their cold dead hands. Yet constantly when it comes to headphones that standard suddenly goes out the window - if you are applying the same criticism for, say, a headphone must have low distortion to be worth buying, then no one can then objectively recommend a tube amp over a solid state amp. Yet we don't see that happen often (or at all). All I'm advocating is that reviewers and community members (not referring to anyone in particular) should be aware and be consistent in applying their criteria. And as I said again and again, don't let me ever see someone saying they bought a HD800 for its superior measurements only to plug it into a tube amp, while in the next breath puts down people for buying a phone such as Z1R that "doesn't measure well" - that's just masking your subjective preference as fake objectivity. Which is what I find the most dishonest practice when it comes to people reviewing gear.
And as far as I know, InnerFidelity hasn't reviewed vinyl rigs or CD players at all.
They have a Wall of Fame of tube amps, some going up to several grand per unit. Strangely no measurement for any of those amps, makes you go hmm? So again, a clear case of applying double standards - using pure subjectivity to review one component of the chain, while then applying a different criteria in headphones.
But also to be completely fair, those devices are not often reviewed by Tyll either, but he did review some too.
This means that reviewers there find components of both types to approach high standards of music reproduction.
Using the same critical criteria for the measurement crowds and applying it equally here - show the measurements to prove it actually approach that high standard. Else it's just a subjective preference.
Or could it be that music reproduction is a multidimensional thing and vinyl does some things better, CD does other things better, tubes do some things better and solid state other things better?
Nope - for vinyls and tubes, even the most capable system they almost certainly objectively does worse in measurements compared to correctly implemented CDs and solid state amps when it comes to all the objectively measurement criteria.
And I see that you have a Woo tube amp in your system. Shame on you for having such a low fidelity device! (BTW, my system is tubed also, and I think it does a great job of REPRODUCING music).
See that's the thing - I never claim to be buy or review my gear based on objective measurements or what constitutes as high fidelity. I recognise that my taste is purely subjective, and for not one second I try to masked that subjective preference with pesudo-objectivity, which is a scaryingly common sight amongst reviews I see around on the internet, unfortunately.
I just like to hold others to the same standards and hate seeing that person who goes around and tell others they are ignorant for buying a poorly measuring headphone has other equally "poor" equipment in their stash, which strangely is actually quite a few of them around on the internet.
