Thumbs up for sure. While I agree that 90% of DSP modes range from useless gimmicks to actual degraders of sound, once in a while you come across a truly useful, expanding processing set. Especially when watching material which is either mono or poor stereo, or just for kicks while having a party to widen the soundstage. If there's no cost, why not. Include even programmable parameters like some of the Yamaha's I've owned, so people can trade DSP profiles back and forth and customize the processing to their every whim.
