You won't ruin anything by recording on 499 vs. GP9, so do a project on each and see if you have a preference.

Bonjour.
I have used Quantegy GP9, 499, 456 and Emtec 900 and 911 all within the last month, so my memory of the experiences is pretty good. My impressions are pretty much as they have been for the last few years:
499: my least favorite in sound. The high end seems slightly brittle to me. Other than 499, I don't really have a quarrel with the sound of contemporary tapes, and in any case, the differences are small.
GP9: lower noise and apparently better bass response (compared to 499). The measured difference was really small, and Jay McKnight says that LF response of tape shouldn't vary with type in any but the worst cases, but I noticed it and so did other people on different sessions. Very low noise.
456: seems to run quieter mechanically through the machines than the other two Quantegy types. There was a period in the 90s when the slitting on their 1/2-inch was up the spout, but it got better until we stopped using it.
Emtec 900: Really smooth performance in the transports. Excellent quality control, nice boxes (Je déteste les boites plastiques!), and other than occasional interruptions in supply (which we combat by placing huge, Novotny-terrifying orders), I can't think of anything to complain about.
Emtec 911: Their 456 equivalent. I would agree, except that EMTEC's QC is much better.
Quantegy were real dicks to us, expending a lot of effort to lose a 30 - 50 grand account. If they are willing to work that hard to lose a 20-year customer, I'll let them have their way.
Emtec, by the way has begun packaging their 900 tape in plain silver reels (Je déteste le swoosh bleu!), as requested by Bob Weston's petition at the Tape Op 2002 conference. Thank you Bob!
