tweak1, that 28K includes the matching preamp. And, there are absolute reasons in using mono blocks. Did Ric say he could add a 2nd power cable to the EVS 1200, to truly utilize the superiority of mono blocking ?, or was that someone else. Having owned so many mono blocks in my life, I would spend the difference for his mono blocks. I agree about Class D. However, with audio, cars, bikes, and several other " hobbies ", it has always been, spend double, and maybe, get a 2 % increase in performance. As far as Ric, I admire his tweaks, as I have been involved with tweaks as well, for so very long. But, I do say, if you can afford it, why not...The economy needs it...You are a 4 hour drive, each way. The same invite back at ya ( bring the amp ). Enjoy ! MrD.
