Greetings, I'm new to the forum - need advise, my speakers are KEF R3 bookshelf SVS 1000 Pro connected with a Stereo receiver Marantz NR 1200 everything sounds okay and to my ears has a good soundstage, a friend of mine resonantly bought a Yamaha N-R 1000 A and he bought it over and we hooked to my speakers, did all the speaker calibration with YPAO. after all done I played Vivaldi's four season, I couldn't believe my ears, the soundstage, the clarity, room filing musical experience it was incredible. I told my buddy I'm gonna keep it. he laugh at me. any way I don't want to give up just yet, I'm thinking adding an amp like the Marantz MM7025 Stereo Power Amplifier, would this be an improved and perhaps give me similar results? before I buy it, I like anyone's thought or recommendations if possible. thank you and wishing everyone a happy Friday.
