Good evening guys! New to the forum here. Seems like a nice community we got going. So the amp blew in the Telluride. I was looking at a replacement but even a used Harmon Kardon amp is close to $700 on eBay. Can I use a different brand amp? If so, would quality be greatly affected? FYI I am no where near an expert when it comes to audio. Thanks for the help in advance.
