next year it will be 20 years for my Evolution Acoustics speakers (had the second pair built), although i did listen to the EA development protype (before there was an EA) for a couple years prior to 2005.
i guess you could say i have a Rives Audio designed room from 2004 also, highly modified over time. it was complete in late Oct 2004. not sure that qualifies. the most spendy piece for sure, and it's appreciated plenty too.
I got back into audio about 2010. About 2012 or so I got the First Sound preamp. Updated it 3 times and still love it.
My Mojo Audio De Javu serer has been updated many times. Probably had that 8 years. Mojo DAC about 6. Updated twice.
Speakers and amps have flipped a bit. Phono has flipped a bit.
Esoteric Audio (Japan) for 20+ years, a series of models moving up the line; owned various models 4-8 years.
