I'm ap I’m currently using a Technics SHA-C500 for decoding DTS, DD. This used to be an add-on to a stereo preamp but now is being used as the preamp. Although it has a LFE subwoofer output, I chose to use a Audio Control electronic crossover at 60Hz to feed the sub. This is the only way that I can use the sub for both bypass (for stereo) and DTS/DD. Would the upgrade to the 950 be reasonably beneficial? Is it worth it?
