Terrific design

Just to tell you how pleased I am with the sound quality of the Icon.  It’s remarkable!!  I’ve always believed the passive preamps do not have a signature sound of their own, but rather simply convey 100% of the source material without veiling or loss of resolution, etc;  Obviously I’m wrong.  The Icon is delivering an amazing quality to my system.   It’s much like the tube sound I had years ago.  Congratulations on a terrific design!
Thanks, Tom
