I’m relatively new to vintage audio gear, but from my experience nothing “ modern” that I have owned, can hold a candle to the sound quality, aesthetics and build of these timeless pieces. I will add that after much reading and research I decided to skip the chase and purchase rebuilt gear from quality techs. To date I have a Marantz 2270 and 2250B. I also own a pair of rebuilt OL Advents to play with the 2250B, and use the 2270 with my Klipsch Cornwall’s. Music to my ears every day.... Now looking for a nice vintage power amp.
