I have not heard the LSA but recently owned a Simaudio Moon I-5. I used it with Green Mountain Europas but didn't like the sound and moved to an Ayre AX7e. I much prefer the Ayre and would highly recommend it to you as an option.
I felt the Sim was brittle in the upper mid range and found it quite fatiguing to listen to. I also did not like the way the volume functioned, the volume steps are quite large and I prefer more ability to fine tune. I did try a number of different speaker cables and interconnects all with the same result.
I did a review on the Ayre under "reviews" if you would like details. Suffice it to say, the Ayre is an exceptionally musical amp with the most accurate instrumental timbre I have heard to date.
