Are you in the over 30 K club??

30K is in my rear view mirror.

I'm close. I'm not proud, just obsessed.

Way over that. If I added up all my audio expenses in the last 45 years I would probably faint. One year alone, I spent a small fortune on PolyPhasors. Remembet them? Passive boxes between all the components and speakers. Supposed to make a big difference, with imaging and sound stage. Another year I designed a 4 way speaker system, Four amps, a Pioneer electronic crossover, Strathern midranges, Pyramid T1 tweeters, Dynaudio woofers etc Bedini, Bryston, Belles and A big BGW power amp for the subs. Sounded horrible, it replaced my Altec 19's and I replaced my design with a pair of Dahlquest DQ10's so I could still use the T1 ribbon tweeters. That was just some of my audio expenditures. It hasn't stopped.

Gulp, I shudder to think! For sure over that between my 3 systems, and as much as I want it to stop it I can't seem to. Main system is CAT Renaissance pre, Harbeth 40.1's, Rega TT, Sonic Frontiers SFS 40 power amp (which is truly a jewel). Bedroom is Naim XS, Harbeth compact 7's, some older Sony CD player. HT system is Parasound P7, OPPO BDP-83, Martin Logan "Feature" & Quad speakers.

How does one turn off the upgrade itch??

My electrical was over $30K !!
