Here's a pic with a G3-A4 clone, to show the relative size of this amp:

I purchased this amp for a project that is now on the back burner, and I'm in need of cash for a more pressing project. It's in excellent condition. I saved for this amp for what seemed like an eternity, and I haven't even gotten to install it in the car I got it for. Hopefully I'll be able to buy another one later on. This amp will make someone EXTREMELY happy, it's my opinion that the McIntosh MC4000M is THE best amp on the market, EVER. $1800
