just wanted to share my NAD :
Hartke LH500 with my dirty old Ampeg SVT-15E cab.
I was GASsing on it for a few weeks and spent some nights, searching for infos on TB.
Tried it this morning with my BDDI and an ampeg 610 too.
No regrets ! Sounds warm, clean and powerful. I still have to find correct settings with the BDDI, but the first impression is really cool !
