[QUOTE="disturbed471985, post: 8370121, member: 611718"] Dosent really help identify what revision but does give you the difference between each - SAX-100.4 -- Original model SAX-100.4B -- Updated crossover ranges SAX-100.4C -- Upgraded from 50-amp to 70-amp power supply transistors SAX-100.4D -- This is the newest model So, what will you be able to do with the new model that you couldn't do before ? 1) You can bridge the amp and actively band-pass a midrange / midbass thanks to x10 functionality on both HPF and LPF on both sets of channels. 2) You can cross-over tweeters much lower with the 24 dB slopes. I have had several requests to implement this from people wanting to use planar tweeters as well, as these require steeper slopes. 3) You can experiment with overlap with the selectable slopes. 4) Most importantly for reliability and consistency... the small sub-cards that hold the crossovers will be re-tooled as double sided boards instead of single-sided. Almost all problems with previous SAX-100.4s were the result of solder problems on the single sided crossover PCB - as uncommon as these problems were we took care of the source! All of these changes will result in a bit longer amp to fit the new crossover boards (about 1.5" longer), but will be worth it for the SQ enthusiasts who will appreciate this type of functionality [/QUOTE]
