From John Atkinson --- "JA’s Saturday at AXPONA" at Stereophile:
"But the surprise for me in the Parasound room was how well the tiny Parasound Zonemaster 250 amplifier (50Wpc into 8 ohms, $475), which uses a ETAL class-D module, drove the Tekton Impact Monitor speakers ($2000/pair). (The Zonemaster 250, with its matching $449 preamp, can be seen sitting on top of one the speakers.) Herb Reichert is working on a review of this intriguing Tekton speaker, with its circular array of seven tweeters, for our August issue."
