The fruitful collaboration between Pioneer and speaker designer extraordinaire Andrew Jones continues with the EX Series Reference Class Architectural Loudspeakers. Demoed without sub, they produced tight, fast, strong bass with the kind of silky midrange Pioneer EX speaker fans have come to love. In fact, they are in the running for best sound of show. Murderously brilliant in-walls. Go figure. Drivers borrowed from Pioneer's more conventional EX speaker models include ceramic graphic tweeters, magnesium mids, and aramid/carbon composite woofers. Pioneer also added two receivers to the line. The more noteworthy one is the SC-07 ($2200) which uses the same digital amplification found in the top-line monster SC-09. If you'd prefer THX to digital amps, try the VSX-03TXH ($1000) which is Select2-certified. Both include HDMI jitter-reduction circuits and are shipping now.
