Best bang-for-buck purchase you have made?


For me, it was buying a pair of used Magnepan MG-12 speakers for $550.00 from a dealer in Oregon. I had heard the 1.6 before, but not the smaller 12's. These speakers have TOTALLY changed the way I listen to music - I may eventually upgrade to larger Maggies, but I think I will always keep the 12's around.

What about the rest of you?

A "Trends Audio" USB to AES/EBU converter for about 200 bucks to attach my laptop to my Zanden DAC. A bit more expensive than the Hagermann, but creating less listener fatigue after long listening bouts, for reasons I still have to find out....
Linn turntable,dynavector 505 arm and dynavector ruby cartridge all thrown free with my first major purchase of electrostatic speakers and threshold electronics 30yrs ago.
Otherwise, a (tested) perfect luxman R117 receiver with remote for $125 on ebay and my (9/10) magnepan 1.6 QR speakers for less than half list price.
Addendum:
Two pairs of Apex signature speaker wires (purchased from on line reviewer) as well as my Cogen Hall EM digital cable. ( I will never part with these cables). In retrospect, these were more of a gift than a sale from the prior owner.
