I own the LAiV GaNM monoblocs and I must say that I'm impressed with their performance so far. I'm using them presently with my 98db single driver speakers (I know... Overkill with power), however they are dead quiet, micro and macro dynamic and sonically are terrific. I see no downside to these GaNM's compared to my Accuphase A48 class-A amplifier. They are compact, well-built and the support from LAiV is second to none. The real test will be when I soon get my Final Model M12+ electrostatic speakers which are notably less efficient and present a more considerable load. However I actually believe they will work very well with the GaNM's.
