I have had the H9 for a few months now. It took a minute to figure it all out, but i'm reasonably familar with it now. 1. It often clips, or if thats the wrong word, i sometimes get a crackly/dirty sound, mostly on delays, unless i roll back the volume. (clean Soldano HR50+, using the H9 power adapter) Someone here on TGP said it clips at +8db, while the Timefactor clips at +20db. It would be nice if these were the same number, as the H9 released later and costs more.(especially this max) ... is there a mod or remedy for the low headroom ? EDIT : I made some progress so i removed the other question i had here. And i want to say that the H9 is awesome the more i delve into it. It usually doesnt clip too badly except on certain sounds, and i felt that my comments were exaggerated or negative. It took me some time to really dial in the sounds.
