I have come close a few years to doing that, but I have really spread out my spending, the most I think I spent in a single year was 15k. The great thing about Amp and Speakers, that unless you are ADTG, you don't upgrade those every year...
This year will be bad for spending too, I plan on picking up an ATI 4007 and 4004 to replace my 3 parasound amps
