Fred Manteghian reviewed the Krell Home Theater Standard 2 in our January 2002 issue, and while he raved about its performance, a few features were missing that any well-turned-out, high-end surround-sound preamplifier-processor should have to compete on even terms in today's hot home-theater market. Those features, as promised, are now available in the Home Theater Standard 7.1. But owners of the earlier model haven't been left out in the cold; the HTS 2 can be upgraded to the HTS 7.1, and while Krell charges $1500 for the upgrade, the HTS 2 originally cost $6500, so your total out-of-pocket costs will be comparable to the price of a new HTS 7.1. And just as the HTS 2 can be upgraded to the HTS 7.1, the basic flexibility of the design allows for possible future upgrades to the hardware and software of the HTS 7.1 as well.
