I think you're only referring to Quad amps. Come on, fess up.
I don't think FM radio can be considered high fidelity by modern standards, but some old, analog FM tuners are cool, like my Marantz 2110. I can always impress the people who don't know what they're talking about with the oscilloscope.
There were some very good speakers, like the Apogee ribbons (I especially like the Scintilla), the Martin-Logan electrostatics, the ADS towers, especially the L1530s, and, of course, the SoundLab electrostatics, which are still in production, and I still covet. But let's face it, these were all very expensive speakers when they were new, and there are numerous designs now for under $5K per pair that perform very, very well.
I completely agree.
