I can tell you I am lucky to have the Lightstar Reference ver.1 (2 Ac cords Dual Transformer and built-in line conditioning) not clear on the difference between the original Lightstar Reference, and the newer 2.0? - anyway I drive a set of Magnepan MG1.6/QR (Magneplanar loudspeakers) with all the volume I need with no apparent need for more, and can say I think it's a very good fit, with a wonderful detail and presentation with a very nice soundstage, - and I compared it to the Sunfire Cinema Grand Series as my friend (Rolland at Hi-tech Audio) had the Sunfire at the same time we auditioned the lightstar, they both could drive anything you want with ease, but I did prefer the earlier model Lightstar to the newer Model Sunfire Cinema Grand Series for my Magnepan MG1.6/QR loudspeakers, in a single word I would say the Lightstar was a Fuller sound. And would be Very reluctant to get rid of this Amp. without having something better to replace it.
