I finally got my 44 magnum, WOW! the difference between it and the Quilter is night and day, now I can hear what people are talking about between a more neutral poweramp and a coloring power amp. With the Quilter it sounded awesome but allot of amps didnt sound right and the amps I did use with global eq tweaks sounded good but always seemed something was off. I got to jam the 44 last night and I can hear the character now of each amp and even feel and hear more of how awesome the Quantum 4 update was, I am blown away. With the Quilter I never went to or above 40 watts so I dont see there being any issues. What I did notice , it looks like the LED light is a clipping diode that kicks in above noon, I am going to remove it and see if I gain more headroom and volume. The 44 mag is clean 44 watts to about 11:00, and they say you go above 44 watts into clipping, I think removing the LED if that is the diode like I think it is, then it should go louder and cleaner
