Glad you enjoyed the combo Deadneddz! I tried to put certain headphones with certain amps based on power needed and synergy to my ear. This is why I had the O2 by itself on the 717 and the Sigs on a T1. IMO the T1 with the Lambda Sig is a very musical combo, a nice step up from the SRM1/mkII. Before I got the O2/717, that combo got probably 80% of my headtime. As I have 3 pairs of Lambda Sigs, I probably wouldn't mind selling you one if you decide to get a pair. I very briefly listened to one of my Sigs out of Justin's BHSE at CanJam and it certainly sounded better, although I couldn't really tell you in what areas as I don't remember all of my impressions from CJ anymore.
