I've owned an Eastern Electric M520 integrated amp for a little over a year now - it has performed flawlessly. This amp retails for ~$1800, but just from looking at it, I would estimate it to cost atleast 2-3 times that - it's a gorgeous piece of equipment. Very solidly built, weighs in at around 50+ pounds...built like the proverbial tank. While this is certainly not the last amp that I will ever purchase (there are other amps I am anxious to hear - various low-powered SET's, Red Wine's new Sig 30, etc, etc...), I know that this piece will always have a place in my home.
