Hello all Vienna Acoustic fan. My current system set up are Beethoven,Maestro,Haydens with REL Stom III, power by B&K components Ref 30 preamp, a pair of Ref 220M for Beethovens, and Ref 7250 II for Maestro and Haydens. Using Audio Quest speaker cable CALDERA for Beethovens as front, still thinking to purchase a pair of Waltz or Haydens to complete 7.1 set up. I always want an Mcintosh amp "MC402" for the Beethoven, but will Mcintosh amp can make a hugh different?
