Vinyl-fetish hipsters don't have a point
Re: "if you're lucky enough to have valves in your hifi when listening to the vinyl, well I envy you.": If you think valve amps sound better than transistors, well I pity you.
I worked with valve and transistor amps in the late 60's as transistors were starting to make inroads into hifi territory. Part of my job as a research technician was mapping transfer functions and distortion of various devices. Valves have an "S" shaped transfer function, whereas transistors are much more linear, but with a sharp cutoff at top and bottom. At 99% max output a transitor is still fairly distortion free, whereas a valve would be up around 50-80% distortion. However at 100% output, the transistor distorts to buggery and the output is full of odd numbered harmonics, which sound awful to the human ear, whereas the even numbered harmonics of a valve are just 1, 2, 3 octave overtones, which the ear accepts as nice "warm" sounds. But, they are not what was recorded; they are still distortion.
Great for a guitar amp where you want smooth sounding distortion, but it is not "HiFi".
Then take into account that valve amps needed a transformer - a transformer! - in the output, with hysteresis, core saturation and all the other non-linearities you get putting audio through a lump of copper and iron - I mean a massively inductive device, and you are not even in the same ballpark as "Fidelity", let alone "High".
Modern transistor amps have come on in leaps and bounds since my day, whereas valves were already htiing their development ceilings back then.
Remember, when Quad advertised "The closest approach to the original sound", (never disputed) they were advertising their transistor amps, not their valve amps.
Oh, and if you are listening to vinyl with a standard arc-tracing tone arm, you are not hearing what was cut with the linear tracking lathe - and don't forget RIAA equalisation adding a bit more non-linearity.
Anyway, this is all moot for me now; as a teenager working in audio, I could hear up to 21kHz, now the only thing above 10kHz I hear is the constant tinnitus from listening to too many loud rock bands!
