CNET shoots down the Dolby ProLogic IIz in Onkyo's TX-SR607 receiver

Onkyo TX-SR607 receiver

Onkyo's $599 TX-SR607 receiver made its way through CNET's auditioning room, and it sounds to us like it holds up Onkyo's tradition of delivering solid performance at entry-level prices. Even though the receiver got dinged for its big, boxy design (which we like, by the way), additional complaints about the unit running hot strikes us as a bit unfair. Given some breathing room, the Onkyo's audio performance stacked up favorably against a Denon 3808CI. At $599, we wouldn't come down too hard on the video upscaling performance; your display might do a fine job on that task anyways. Ah, but what about that new Dolby ProLogic IIz that's supposed to raise your roof? Well, it didn't seem to work for CNET at all -- on a variety of source material and even with boosted levels fed to the height speakers, the effect fell, well, flat. We'd suggest trying out DPL IIz before jumping into the multi-channel arms race.
