hi Miguel, I've had my Lyra Connoisseur preamps for a number of years (they started out as 4-2 spec & were updated to the current 4-3 spec in Dec 2012). I consider them essential in my system.
I was most impressed by your Tripoint Troy Signature as well (I ordered my unit blind & had no idea what to expect). was very pleasantly surprised by the additional naturalness & clarity. bravo!
