I've been using the latest Spectrons as monoblocks for a few months, and have been very happy with the sound as compared to my previous Rowland 201 monoblocks. About a week ago I upgraded to Elrod power cords. I'm using the Elrod Statement going to my power conditioner, and two Elrod Signatures going to the amps. Right out of the box, the Elrods sounded good. Since then I've noted gains in three-dimensionality and clarity- a more "fleshed-out" and realistic presentation. Although its only a week, I'm convinced that the Elrods help bring out the goodness of the Spectrons. Of course the Elrods are true components rather than tweaks- hence the name Elrod Power Systems.
