How long do you or should you keep your gear.

There hasn't been much of anything that I have ever kept past 10 years or so. The one exception that I can offer is a Carver C-9 Sonic Hologram unit. I only say that because I can switch it in or out of my system. Also, when I own any electronics of that age, changing out electrolytic capacitors is a given! Likely the RCA jacks a close second. Yes folks, caps do age and will eventually cause some sort of trouble. Having said that, I believe there are numerous products made back then that simply slipped through the cracks or out of favor as new ideas came to be. Quad and HT were murderers to a host of already good gear at the time. Then there were victims of one hit wonders>> Sony's El Cassette or digital tape decks never had a chance to make much of an impression. 

This hobby allows you to keep what works for you (and still operates properly) or change in new items as fits your mood.

While I have several new items in my system, I still love my Denon DP-2000 drive and my Stax UA-7 tonearm. These pieces are mid-70s classics so that makes them about 46 years old.

Enjoy what works for you.

Happy listening!

@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. 

I follow one rule very strictly: I will never commit to buying a single

new piece od equipment without having the requisite cash on hand.

"I’ve been an audiophile since Nixon was president... But now at age 70, I’ve gotten to Audio Nirvana.

... But then I fire up my custom built Linkwitz Orions and urge to make a change goes away. I’ve had my Orions for 15 years now and they are my forever loudspeaker. Being multi-amplified and calling for 8 channels of amplification, you don’t readily change out your power amp..."

Me too... 

I've had the Linkwitz 3.4 Orion's for 5+ years now with his ASP and the ATI 6012 multichannel amp (his set up).  And... like you... I think they may be one of the best sounding systems available.  I've got Harbeth 40.2's, Magnestand 1.6's (modified Maggies), and others, but - I think the Orion's top them all.  

I have thought about getting the LX521's from Madisound, but I'm not sure their sound would be much better.  

Just wondering if you ever had the original setup and how the set up you noted above is much better?
