Do you mean the 8200P (stereo power amp) as opposed to 8200M (mono power amp) which mean you will need two? either way given the power of the K2 i dont really see much to gain, or if you would indeed notice much difference, sure might be a different nature to the sound, but for better or worse impossible to know until you listen for yourself, even if it cost nothing to do, in terms of difference, id be surprised if there was enough difference to make it worth the hassle, as for aesthetics that would more worthwhile if it cost little or nothing to change providing the was little difference in sound
