Oh Forgot:
Anthony, please do some more research on the monos.
They are in fact IMPROVED !!! Symphonic Line RG 11 monos. Much improved, and these amps have reference status' in several versions all over Europe and parts of Asia, such as the stereo unit, monos, or the amp stage of their big, expensive integrated. All the same design, which is also our Stratos. Now, the Stratos has a much improved case, and a much, much better power supply. With the Xtremes, we simply went nuts, and the results were astonishingly good, especially on the (real) power and stability issue.
Now, as for the $$$, I don't think that you realize that the standard RG 11 mono version used to be $ 7,200. So, in fact we're not talking about 2 K here, but a pair of 7 K +, for which you just happen to pay only 2 K +. US manufacturing instead of Germany, reasonable margins on our side, and factory direct (still with 20 years warranty, and keep in mind that I'm doing SL here in the US for 15 years now !!!)
I'm sorry if you paid more for your amps.
Late,
Klaus
