FM - Switchover

PS and no they are not, just when overdriven their behaviour is graceful
compared with clipping in semiconductor amps.

Yep, even harmonics, which the ear generates internally, and thus are less
offensive than the odd harmonics you get from overdriving a transistor amp.

I detect a certain topic-creep here!

Would it be short sighted to buy a stereo system that does not have DAB?

I can't believe they're contemplating turning FM off....it sounds
wonderful and 'warm' compared to DAB. And yes, I've been all over Europe
and heard the higher sampling rates.....it still doesn't compare.

Surely it's the other way around? On my DAB/FM radio, the soft, warm,
mellow, and sometimes burbly DAB audio spares me from being assailed by
the harsh, tinny, high frequencies which are often present in the FM
audio.

Oh dear it sounds like we are heading to the valve amplifiers are better

That's an idea. I'm now listening to DAB via valve amps!
The best, or worst, of both worlds.

You left out the tendency for valve audio power amps to have a high o/p
impedance. That tends to cause an alteration in the frequency response when
connected to the loudspeaker. Sort of expensive 'tone control' effect. :-)

Slainte,

There will be no FM switchover. Ofcom or whoever suggested this idiotic
idea are totally clueless.

Think most would agree with that.

If any of the ILR stations switch exclusively to DAB they will lose
every single one of their listeners to community radio. DAB is finished.

You have some information which proves it won't just continue as is?

It's already uses outdated technology which is over 20 years old so the
entire existing platform will go long before FM does.

The audible faults of even a half decent valve amp are minuscule
compared with the atrocious sound of many UK DAB stations.

Better still actually make them the shape of other items, like door stops
etc, so they can have a second use.

Incidentally whatever happened to that digital radio mondial' or whatever
it was called?

They realized it was even worse than DAB.

DRM+ is a bit better.

By that yardstick how old is FM? 50 years? And it's outdated too. No one
starting with a clean sheet would do stereo that way.

And the audible faults of a poor valve amp are large compared to some DAB
UK stations. Since we appear to be comparing apples to oranges.

And yet the people starting with a clean sheet have delivered something
worse.

A nice comment, but a little unfair.
What they delivered was pretty good. It was the subsequent
cheese-paring of bit rates that made it worse.

If FM deviation had been reduced to fit in more stations, its quality
would be similarly reduced.

It started out ok. The bitrate was reduced subsequently. And much FM is
ruined by over processing too.
