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!

In descending order according to MSRP:

Line stage pre-amp, phono cartridge, pick-up arm, SACD player, power amp, turntable, phono amp, loudspeakers, subs.

The pricing is complicated by the fact that some pieces are DIY, some used, and some vintage. So the prices don't really reflect anything in particular. A completely different list would result from the actual prices paid.

For a while it was Super DH Cones, I must have had fifty in the room, under components, under speakers, under furniture, on top of speakers and under stacks of those 4" ceramic tiles that were kind of a passing fad about ten years ago, sometimes crowned with Brilliant Pebbles. The Supers ain’t cheap, either, $150 for a set of three.
