With all this talk on upgrading mono's....can anyone tell me how much the upgrade costs to go from from Mono Extreme's to SE (or what ever they're called). Can anyone articulate the differences and if they're worth the investment?
Oh yeah, please don't just tell me to "call Klaus". I also think highly of him, but he's obvoiusly busy and I'm busy too....just hoping someone on this thread (Lazydays?) can give me the toplines please.
Thanks in advance! 
I sent my mono blocs to him in person, and had them back in my hands in about a week! As for the upgrades there are several levels, and it seems like they range from a little over $500 to about $1300. When I handed them over to Klaus, I told him "to give them the full tilt boogie."
I can tell you this they came back ten pounds heavier! The reason I did it this way was because I plan on using them for a long while, and can already see that wresteling with these things are not a thing I want to do often.
I think when I gave Klaus a call about upgrading the amps I caught him at the perfect moment as he kinda had an open spot in his schedule.
I do know he's waitting on parts to come in right now, so maybe you might want discuss this with him. I do know he has several options andI also think paths of upgrades. I basicly let the designer and builder make that decsission for me as I think he knows a little bit more about these amps than I do. How do they sound? Havn't a clue as I'm still in the process of hooking them up in a temorary system.
