Default how good are class D amplifiers?

Just an opinion: history shows that despite 'progress' amplification
quality diminishes every decade. Don't believe you can't do without
this new class. A good system dating from 1960 or 1970 or 1980 will
beat any plastic rubbish -whatever class- dating from 2007.


Interesting opinion, but what is it based on? Modern systems are
louder, distort less, have wider bandwidth and less noise than 1960s
or 1970s systems, but haven't improved to any great extent since the
'80s. However, they certainly haven't diminished.


Well, I'd be happy to believe that amplifiers have 'deminished' over the
decades. I am still enjoying using the amps I designs 20+ years ago. So it
would be smug to assume that newer ones were all poorer. However I suspect
the 'opinion' remains an 'opinion' for the simple reason that it isn't a
'fact'. ;-


Hi Serge,


My opinion is based on human hearing and not on the momentary
technological approach from a-musical tecchies.


Strangely, I also based my opinions on this on 'human hearing'. Just that
my experiences clearly differ from yours, I suppose. :-)


I got to this opinion speaking with fellow musiclovers, who share a
passion for the best obtainable. Most got tube amps under 5W per
channel, some built their own, often accomplished by single driver
speakers.


Ah, so 'the best' means soft clipping to alter the sounds in ways you
prefer. I see. Do you also regard high output impedance as useful to alter
the frequency response in ways you like? :-)

Slainte,

Jim
