Using a 1/4" tape machine without noise reduction, especially at 15 IPS is an exercise in the art of compromise, unless all you are doing is rock and roll with little dynamics. There's far less compromise in my opinion with 1/2" and there you can play with the sonic differences between 15 and 30 without feeling like hiss is not your friend. As the hiss level of 1/2" is much more acceptable. In fact, I find the hiss level of 30 IPS 1/2", 320 nW/m with GP9 to be subtle and "soothing" and for most music, 15 IPS 1/2" to be quite acceptable.
15 ips seems to be more linear. i find the low end at 30 ips goes a bit aray (spelling?). though as you rigthly say , the hiss has a smoother quality.
hence the dolby SR i use at 15ips.
i'm totally with you on 1/2" though.
