The CLR is about the only one that I've never had, but it beats hands down any other one. As a reference I had: Blue Amps, L6 PowerCab, DXR-10, EV 12, Mission Engineering 2x12, Laney 2x12 (very impressive, but weight and size are excessive, like a 4x12), HR 108 (this one was so bad!), QSC FR12a, Powered Kabinet, Catalyst 100. The main thing is that it doesn't sounds and feels like a PA speaker, but like an actual amp. Particularly impressive is that it's a closed back speaker, but with the Cab emulation of an open-back one, it really sounds like the back panel dropped off. Same when you use a 4x12, you just can't believe the sound is coming out of this 1x12. I can only recommend at least to try it.
Thanks for your input, I gotta try the Fender. I can't find one within a reasonable driving distance so I'll have to order one. I'm at the point that this may be my last effort, if it doesn't work for me I'm considering going back old school.
I got the Kemper rack in 2017 and for four years I ran it into the effects return of a Fender Mustang III, picked a stock rig and just played. I had an EV ZLX12 at the time of purchase and tried it but didn't care for it.
In the last two years at stores I tried a passive Kabinet and the Headrush units. I ended up purchasing a matching rack and two 112 cabs to load my own speakers in for a stereo setup. So far I've bought and tried the first generation Kones, the Neo Kone, but settled with the Eminence EM12's.
I'm almost embarrassed to include the other's I've bought in that time frame but here they are nonetheless. Two Yamaha CBR10" passive, a powered Kabinet, a QSC CP8 powered, and last week an ISP Vector FS-8 that the power section shorted out on after four hours of use yesterday, so back it goes.
By the way, it looks like the hiss can be fixed if a person is willing to open the unit up, remove and solder in a couple of replacement parts. Details are on the Fractal Audio forum, but it would be a little daunting without pictures or maybe a video for reference, at least for me.
