Modern violin players are still trying to recreate instruments that sound like the Stradivari
A blind test already debunked the Stradivarius myth. People, including elite violinists, actually preferred the sound of the modern violin*. Again, it's all about nostalgia and status.
There's an actual term for this longing for the past called Rosy retrospection. Even pro musicians are not immune to it.
The most technically-proficient guitar players (Vai, Govan, Malmsteen, Batio, Buckethead, etc.) all play guitars of their own design, not vintage ones.
Your Prius analogy is flawed. In keeping with your original cars, I'd take a new Lincoln Continental over a (new) old one. The new model will ride better, handle better, stop quicker, last far longer, be safer, have a better sound system, have more comfortable heated seats, have tires that last at least twice as long, an exhaust that will never rust, a body that will take far longer to rust, and be quieter.
As far as CDs, almost all mine have been sold. Why waste the space and suffer the inconvenience when I can stream and play almost any album in existence, by voice-control no less, for $150/yr? As for LPs, I gave those away in 1990.
Time marches on.
