I heard the 40.2 driven by Vinnie Rossi's newest design amps at Axpona 2018. Wow! I also heard the SHL 5+ 40th anniversary speakers driven by the LIO integrated at Axpona 2017. Based on what I heard I bought a pair of the SHL5+. As impressive as the Lio integrated sounded, Mr. Rossi's newest creation is a clear step beyond. He is a true gentleman and very personable. If you are so inclined I'm sure you could call him for more info.
