Hi,
There are much fewer innovations compared to the 80's and 90's.
We had CD, DCC, Minidisk, MP3 proliferation, and DVD/blu-ray. There is nothing new occurring, since speaker designs, amplifier designs, etc., are just being refined. Class D seems to be the latest change, but apart from that, no major new invention.
Anyway, hifi is a dying hobby and those people that still enjoy are reducing in numbers. This forum has worldwide access, and yet we still see many of the same people posting repetitively.
Regards,
Shadders.
