I have an unpowered Kemper, and I'm thinking about getting an ISP Stealth power amp to power it through a 4x12. Has anyone had a lot of experience with this and how well it works, especially in comparison with a powered Kemper? I was contemplating jumping up to a powered Kemper, but figure I could save some money by just getting the Stealth as an option for my current one.
When reading about the Stealth I was a little confused by the outputs and whether it supports 16ohm in the mono bridged mode. I have a Marshall 1960a with 4ohm and 16ohm mono options, and 8ohm stereo if I had a second cabinet which I don't.
