Wow, are you sure about that? I really hope that's true. I use high output tape exclusively, but I always harboured some guilt over the belief I'd be wearing out my heads faster.The 1st time I heard this myth was on this forum. 499 maybe stiffer than 456 but not any more abrasive.
FWIW I've been using mostly RMG SM900 (plus one reel of ATR) on my Tascam 58 at a +6 operating level for a while now with no problems whatsoever. I was able to get it bias correctly.
For my MS-16 I replaced the bias feeder capacitors (a very quick and easy job) and I've been able to get ample bias to operate ATR tape at +9 levels. (I didn't actually try biasing it before the mod, perhaps it would have worked fine, I got antsy waiting for the tape to show up in the mail).
BTW after using a couple reels of ATR I can say I like it every bit as much as the old 3M996. I'm really rooting for these guys to thrive. They make a superb product.
That said, good luck in your 456 petition all you folks who prefer it!

, but it is stiffer. Big picture? 456 is gonna wear the heads...499 is gonna wear the heads...dental floss is gonna wear the heads. The question is "how much faster?" I have no idea, but my guess is that it is not something to freak about, and may be insignificant y'know? You are running +9 tape because you like how it sounds...it isn't a physical issue with your tape path, its an artistic issue and I fully support that. Maybe in the big picture, over a long period of time you'd get 50 more hours out of your heads with 456? Maybe 10? Maybe 100? I have no idea, but you're not running sandpaper through the path so right there you're off to a good start.
