I know what you guys thought a for sale ad but its not. How many are willing to spend around $200 for a near new Arc Audio 4150XXK amp that works perfect and looks new. Just wondering if this is a good deal or not. Also will this amp outperform the ED nine.4? I was planning at first to purchase the Nine.4 but then I found this amp so wondering if I should've gone with the nine.4 or not.
