There is not a receiver made that can match this unit's sound quality. If you include the DTR-9.1's broadcast-quality video switching, it outperforms all others hands down. And if you're looking for a home-theater centerpiece that will grow with your needs, there is basically only choice - the DTR-9.1. THX Ultra certified and outfitted with THX Surround EX, DTS-ES, Dolby Digital, DTS, Dolby Pro-Logic II and even DTS Neo-6, along with an expansion port for things like IEEE-1394, an RS-232 port for control, and powerful flash memory that can be updated anytime with a new surround format, this home theater wizard is set for the future.While other receivers offer video switching, very few can switch component-video signals, and even fewer provide component-video switching for 3 devices. The DTR-9.1 goes a step further to give you an option no other receiver gives you - broadcast-quality video switching that has sufficient bandwidth - up to 50 MHz - to ensure loss-free routing of images from progressive-scan DVD and even HDTV sources.As good as the video is, it's the DTR-9.1's audio performance that clearly puts it in a class all its own. The resolution offered by the AKM 192 kHz/24-bit digital-to-analog converters for all seven channels is nothing short of extraordinary. These state-of-the-art DAC's, the same used by many esoteric manufacturers, also deliver an astoundingly wide dynamic range - up to 120 dB - wider than any receiver we know of.Additionally, they allow you to digitally upsample conventional 44.1kHz/48kHz to 96kHz/24 bit resolution.The DTR9.1 also boasts exclusive linear optimum-gain volume circuitry to give you a S/N ratio that exceeds 100 dB - a refinement that helps deliver a purity of sound that other receivers simply cannot match.
