Sorry in advance for my flip answer but, when I set the level of my lfm-1 the true limitation is how loud I can set it without rattling things in my house. I had an interesting experience recently. I've been listening to my 5.1 setup for months now. When I went downstairs to listen to my living room stereo it sounded incredibly bass-shy to me. I've gotten used to steak; hamburger doesn't do it for me anymore! LOL!
