Atmasphere Novacron MA1.5 amp with Merlin VSMSE

I am currently using an AA Capitole MKI with a pair of Quad II to my VSM. However, yesterday I come across to see an Atmasphere Novacron (MA1.5) for sale at one of the local second hand shop for a fairly good deal. I am just wonder did anyone have experience with this amp, and should go ahead for an upgrade or not??

Thanks for you guys input in advance.
