The only way I would recommend running the Orion HCCA 250 gen 1 is if you actually had the amplifier and the bridging module to go with it. If you are having to buy from scratch, I recommend you go with the Sundown.
Don't get me wrong, the Orion was a beast in its day. Sadly, its capacitor life is at the end of its useful limits and you should get them replaced ASAP should you decide to go with the HCCA! I am talking about the power supply capacitors as well as the audio filter caps //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
