Mackie 0 Report post Posted October 5, 2004 (edited) Slew rate. This is one of the most important factor. It is the ability of the amp to reach high voltage in the shortest time possible. The unit is volt/micro second. The higher the slew rate the better the imaging of the amp. With high slew rate op-amp, we can hear more seperation between the musical instruments and singers, and we can locate their position easily. In addition, higher slew rate denotes better control of output transducers (drivers). In the context of amp and speakers, this suggests bass handling capability ie, push-pull motion. Edited October 5, 2004 by Mackie Share this post Link to post Share on other sites

Q00 0 Report post Posted October 5, 2004 Might i suggest for those starting their foray into diy also learn to make their own cables? Proper cable termination would be a 'good thing' to learn while u make yer amp. Ive seen quite a few very nice diy cables in here that can compare favourably against some of the more expensive brand name ones. Share this post Link to post Share on other sites
