BEST 90's Audio Gear that holds its own today.

Your list if any.
With the exception of digital products, anything that was competitive in the 90s should still be quite competitive now. it's not like there have been any fundamental advances in sound reproduction in the past 15 years. A lot of worthwhile refinements, but nothing earth shaking.
I agree with Onhwy61...pretty much everything should still hold it's own, maybe even some of the digital stuff?

I own some 90's gear so will mention those:

Krell Ksa-250/Amp
Apogee Duetta Signatures/Speakers
Audioprism Mantissa/Tubed pre-amp
