A life sentence!!!

Schitt Yggi+ OG DAC.

My McIntosh MR80 has been in my rack since 1980 and isn't going anywhere.

Diy modified Klipschorns. Much research and listening to get them to excel in all areas.

WaveTouch Audio Antero Speakers. 

My Pass Integrated 250.

My Silverline Bolero's. They succeeded Quad 63's and Paragon Jubilee/Gems. I've been running them for over 12 years now. FWIW.

My Maggies. I've tried quitting them, but always go back.

Acoustat 1+1 speakers. I have had them longer than my marriage which is approaching thirty years in a few months. The whole audio system is built around these speakers.

Octave Audio Jubilee Preamp

MSB S-200 power amp... 

For me, my Musical Fidelity CD PRE 24, a preamp/ CD player.  Going on 22 plus years in my system.
