Where did you sink the most cash into?


I'm not interested in how much anyone  spent, but I'm curious what the single most costly item in your system is- ie, amplifier, CD player, etc.

I will go first- in my present set up, it's speakers. 

But I can't live without my ancient Zerostat (the red one) which was probably 1/3 if what they retail for now. My most enduring audio purchase!

Turntable/tonearm. Spending 50% on speakers is not old school, it is only one of popular approaches. Old school is to creatively and individually approach the subject but never have a weak source.
When I started out the conventional wisdom was 50% on speakers! And with my first system, all of $400- a $75 turntable, a $125 receiver, were complimented by $200 speakers! 
IMO, it used to be that the loudspeakers took a bigger percentage of a system's budget because good speakers cost more relative to the source and electronics that what you can get now. Loudspeaker research has really paid off, as it costs relatively little to get pretty darn good ones now, don't ya think?
