Still happily using vintage gear?

5 years ago I had my parents HH Scott 350a receiver restored.
It sounded pretty nice too! 
My DAC and Streamer are newer but my Tannoy FSMs are
1987ish and they are going nowhere.

Yamaha MX1, MX-1000, NAD2200 sound as good as any equipment built today with Nautilus 803 made in the 90s.  And did I say MX-1000 still looks so sexy at 240wpc, 2ohm stable. :)

While this old guy can’t boast the creme de la creme of audio components or even true “vintage” gear, what I have is approaching 30 years old and while I could find the energy given the funds to delve into an “upgrade”, I wonder if the time/ money investment ratio to actual listening pleasure would improve enough to these old ears to justify such an endeavor...
The first “real stereo” I heard was a Pioneer receiver/ speaker set up and unknown turntable ~1969-70.  Blew me away and was my earliest audio motivator until my current system gave me peace...What I have gives me a smile and a sense of awe and inspiration everytime I hear a great piece through it!

I recently added a Yamaha RN-303 receiver to facilitate wifi/ digital and to power my 25 year old Boston Voyager outdoor speakers.
My original Yamaha receiver that powered outdoors passed after 25 years.  Keep the music playin..
