Would These 3 Vintage "Best" Speakers Still Be Contenders Today?

[audiobomber]

I owned a pair of Yamaha NS1000M speakers, purchased new in 1975 for $1000. I should have kept them, probably the worst mistake in my audio life, but I contracted audiophile fever and traded them off a few years later. I drove them with a Yamaha NS-1000 integrated, which was not close to showing their potential.  I absolutely believe they would be awesome value in today's market at an inflation-adjusted price of $5000.

 

Crossover components would all need to be replaced long before now. Active crossovers would be interesting with the beryllium drivers. The 12" woofer was mounted in a sealed birch cabinet and delivered a very tight and honest 40Hz. 

 

I heard the modern replacement (zylon drivers, no beryllium) at an audio show. They cost $18,000. The sound was spacious and very detailed, driven by an expensive Yamaha front end CDS3000 CD/SACD player ($7500), C-5000 preamp ($11,000) and M5000 power amp ($11,000), but disturbingly bright. Needed a better room and/or system matching.
