My Hypex sub amp started having problems after 9 good years . Wish I had a O-scope, it would be a fun project to trouble shoot it at the component level. After some adventures, I got a Crown XLS 1500. With all the bad mouthing of the Chinese stuff, and my distrust of class D, it wasn’t my first choice.
I hooked it up to the L100s and it sounded better than the Mac 1900, their clarity and tone were never so good. That took me by surprise, maybe the Mac needs to go in for an overhaul. I took the top off and it looks real nice inside, but everything is miniaturized. It’s hard to believe it can do what it’s supposed to. 1550 watts into 4 ohms, freakin amazing, the bass is so tight with this thing. I can’t say how it would have done in Mr. Scotty Fitlin’s house, but for home use on a subwoofer, I don’t see how I could have done better for the money. For $400, it murders any plate amp I’ve used. The old 2241h never sounded so good. If this is what they are doing in China, rock on, Harmon!
