Trinnov technology gamble for Sherwood Newcastle
If by "gamble" you mean throwing the dice and praying...then no..it's not good. If by "gamble" you mean providing leading-edge technology that has already been field tested in a $13,000 system and providing it at a $500 premium for their existing line of AV receivers, then yes, by all means, go for it! In business/marketing terms, it's called having a "competetive advantage" and just like the Reon chip in the Onkyo receivers it will make buyers hungry to upgrade their systems consider Sherwood Newcastle (at least in the R-972 version), a relative underdog to Denon, Onkyo, Sony, Pioneer, and Yamaha as things stand.
Video upscaling via receiver is more controversial since there are so many good upscaling DVD players, but room EQ is a hot topic and most HT's would benefit. Compared to the full cost of the Trinnov stand-alone system or remodling your HT acoustically, $500 premium (less at street price?) is a VERY reasonable cost to pay - if the resulting listening experience is perceived as a definite improvement over Audyssey etc.
