they should have some burn in but I doubt 100 hours.
recommend you try different tubes before you decide if tubes are for you or not
Tack on another 10hrs today, I'll be getting there soon enough...
I haven't even broken the ice yet, just an initial assesment, how many times is that right in the end? I just threw in PF - Animals, DAMN what a difference!
I'm thinking I might hear a much more drastic difference in source material, I'd have a lot more things listed but I couldn't swap out what few things I've played...
Any chance you could look over that cheesy diagram I made in the other post Trey and see if I'm biasing the tubes correctly?
