I’ve had the top 4 AQ IC in my system ( 2 M XLR ) between REF Phono 2se > REF 5se for 2 weeks ( this is where it helps to have a relationship w a dealer w muscle = Audio Ultra in Seattle ). You can see pics of the rest of the system ….. AQ wild Blue out to the monoblocks on the virtual system pages. IMO Pegasus and next higher are value game changers…. great copper bass that gives up a whisker of definition each time you climb higher in Silver…..
Best to you in your musical quest !
Ref 750 w 6 is quite something :-)…
