First Watt SIT-5 Monos

6 Moons and the First Watt website list the SIT5 at 35watts @ 8ohms,and 60watts @ 4ohms. I am currently driving a pair of Graham Chartwell LS3/5’s with a First Watt J2. That’s 25 watts @ 8ohms,and 13watts @ 4 ohms. I find that very sufficient. Best of luck.

It's near/mid field listening at about 5ft.  There should be a way to calculate the spl the lp compared to the Classe CA-150 I'm currently using.

AI suggests the difference in max spl is 6.5 db.  But there may be a clipping issue?

Thanks @rocray !
