Motorola transistors

My amps currently have 15003/15004 transistor set. I've read that the 15022/15023 transistors are faster than the 15003/15004, has anyone tried the newer ones or can tell if changing them will have a noticeable effect on the amplifiers?

Thanks.

. . . and actually newer, better, and more closely matched out of the box than the 15022/15023 is the ON Semi MJ21195 (PNP) and MJ21196 (NPN). Currently, I'm in the middle of totally rebuilding a Threshold Stasis 2 using these.

Lot's of good info in this area at http://www.diyaudio.com

. . . but you probabaly won't hear any big difference by changing output devices from one revision to another. The main thing is to make sure that the bias is correctly.
