Which Surround Sound Processor is right for me?

The answer, of course, depends upon your priorities and your application. There are many issues to consider.

Issue / Feature Recommendation
Ease of Use Surround sound processors vary greatly in how easy they are to set up and how easy they are to use. If we will be installing and calibrating your surround sound processor, then ease of setup may not be a concern. If we will be installing a custom-programmed remote control system, then ease of use of the processor itself may be irrelevant because the control system we design will (we assure you) be very simple and clear to use. Otherwise, be sure to select a surround sound processor that makes daily operation simple.
Digital Audio Quality When listening to digital sources such as CD, DVD, or satellite TV, the audio performance of the digital-to-analog converters in your surround sound processor will be crucial to the overall sonic performance of your audio system. Remember that surround sound processors have 6 channels of D-to-A conversion; an equivalent level of performance in a surround sound processor is more expensive than in (say) a 2-channel external D-to-A converter.
Analog Bypass Will you be listening to high-quality stereo analog sources, such as phono, tape, or the analog outputs of an external CD source? Then you should look for a processor which offers an analog bypass mode, where all digital processing is avoided. This will maintain the purity of your analog signals.
Music If you will be listening to music through this system, then you may wish to judge the sonic performance of the surround sound processor just as critically as you would a stereo preamplifier. Listen carefully and we think that you'll find that some surround sound processors offer very high sonic performance indeed, whereas other fall short. Depending upon your situation, you may find that your requirements are best met by designing your system to bypassing the surround sound processor entirely for stereo listening. Please feel free to consult us for advise.
Dolby Digital You must have this for DVD or Satellite use. Our advise: don't even think about a surround sound processor that doesn't offer it.
dts An alternative digital encoding standard. There are dts audio discs available, as well as DVDs with dts soundtracks. Almost all DVD rentals (at least in New England) are Dolby Digital, not dts (unless the disc has both). dts has the potential to sound better than Dolby Digital, but this is only sometimes the case, depending upon the disc. Most of our clients consider dts nice to have.
Video Switching Many surround sound processors have the ability to switch your video inputs to follow the switching of the audio inputs. This is both a convenience and a method of expanding the number of video inputs. Some surround sound processors also offer on-screen displays of the surround sound processor functions, which may make setup and use easier. If you want to use video switching in your surround sound processor, be sure that it supports enough inputs of the type you have (composite, s-video, component, or RGBHV). For the highest performance, you may prefer a dedicated external video switcher.

Options may be added at a later date, and updates are simplified. Theta has an excellent track record of keeping its product current through updates. Also, both have excellent user interfaces. All functions can be accessed from the front panel (which is important if you lose the remote control or the batteries run down). There is a clear LCD display. Setup is some of the easiest we've seen (given its power and flexibility.
