The Audience FrontRow USB was only a few hours old
@fire_water Yeah, get in the habit of giving everything at least 100 hours, in most cases 200 hours before coming to any conclusions, and especially not writing it down. If it is a Furutech GTX outlet, (or anything with NCF in it from what I gather) more like 500 hours.
I have experienced the above with components and cables, but tubes? I just burned in a Mullard 7308 tube that radically changed between 40 and 50 hours (for the better). Everything I have read regarding that tube, and other input/signal tubes stated a few hours, 20 hours tops, whereas larger power tubes may be up to 200 hours. Of course there are many comments from people stating there is no change, but well, you know, they don't know.
I called Brent Jessee to ask his experiences and he confirmed all tubes could take upwards of 100 hours. Now I know.
