@builder3 As far as I'm concerned, the SX 50 series was the high point of vintage pioneer receivers. The 750 is stupendous. I remember I so wanted a SX650 but my teenage budget could only stretch for an SX450, which to this day I remember fondly. I no longer have it as I loaned it to a relative who after a few years moved to a micro-system, and promptly discarded the 450 without asking if perhaps I would like it back.
How long do you or should you keep your gear.
Another interesting article and may spark, debate, reflection, envy?

For your enjoyment and Happy Holidays.
