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!

Equipment purchased new: Speakers followed by the CD player.

Equipment purchased used: the amp

Cables and tweaks less than 10% , overall.
OK, I finally decided to chime in:

About 25% each on; speakers, Amp/pre, DAC & USB converter, cables. Everything bought at discount, hence percentage does’nt reflect retail price.

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.
