I'm really saddened . . LCDs .. ugh . ..

Having just returned from some early Seasonal Shopping, from a well known Shopping centre, at which I was confronted by the standing Stygian ranks of LCDs on offer . . .I'm truly saddened. "The horror. The horror"

Yes, the images were sharp enough to slice zircon at 10 kilometres - but but but . . those BLACKS??? Flat as pancakes, whites blown apart and DON'T get me started on field ( or whatever it is called nowadays!) and pixie separation . .. I stood there, with James Bond leaping about and the mountains of Switzerland glistening with blown whites against a blue sky that would look great on a postcard. I'm sad, really . . .not a single CRT on view.

Sad . . sad . . sad . . and you know what? It's what our youngsters and rising middle-agers are seeing as "GREEET!" - it really does seem that, forget the quality feel the width!

Folks! This HAS to change.

Rant kinda over . .. well not really, I'm sitting here in London quietly seething.

Am I the only one who sees this? It's like the Invasion of Body Snatchers all over again.

Oh yeah, "The Horror .. . " etc, I'm just kinda wondering just WHAT that haunting, eerie, dark-Brando "Apocalypse" scene would look like on one of these £2k brutes?

Grazie

The newer CD's are really pumped up level wise sometimes 15 db worth without causing any audible distortion.

Are you talking about subjective loudness? Big subject, but it's not helping sound quality per se.

I agree that low-jitter ADC/DAC clocks makes a huge difference when listening to digital audio, not cheap to get really good though.

Transformers were indeed a real factor in tube designs, but a lot of work was put into successfully reducing their inherent problems to the point where the result was very enjoyable.

Speakers used to be 8 or 16 ohms, because voltage was easier to come by than current (due to high output impedance).

Today most speakers are lower impedance, because for transistors current is easier to produce (due to low output impedance).

So speakers that sound good with low-Z transistor outputs don't necessarily sound good with high-Z tube outputs.

John, I didn't quite understand what you meant by "little or no negative feedback" in the speaker context, unless you meant the high damping factor you get with a low-Z output (back emf from speaker flab gets "shorted" which greatly reduces the flab).

Edit: More negative feedback will of course reduce the output impedance, was that what you were referring to?

Yes.
