I also have the I5.3 and love it with my Contour 1.4's. My understanding is that the I5.3 includes the LE's electronics but with more power. Sim also gives a 10 year warranty!

Anyone compare the Simaudio I-5LE to the I-5.3?
Just curious if anyone has conducted a bake-off between the two integrated amps, and what your impressions were. I did hear the LE once, which was something truly special, and I'm getting ready to pull the trigger on a purchase... many thanks in advance!
