Prima Luna Prologue Preamp

Replaced my crusty preamp today with a Primal Luna Prologue.  Was hoping that Carver would have a tube preamp out by now, but couldn’t wait.  I am amazed how well the new preamp sounded out of the box.  It sounded so much better, I’m now wondering if my old preamp was failing.  It sounded like I had new speakers.  Very happy and it’s not broken in.  Built like a tank..40lbs... Looking forward to it breaking in.....
