Legacy Audio Steradian for sale. This is the original Steradian processor. I believe it was made for Legacy by Coda. Rating as 6 of 10 due to a couple of small scratches along the top of the front face and several other small scratches on the top. This unit is very presentable and could be just as easily rated a 7 of 10. It is used to adjust the bass output of the speaker connected to it as well as increase channel separation. It was specifically produced for Legacy speakers such as Classic and Focus, but will work with any speaker. I do not have a manual for it, but it is similar to the Step One, which can be found in the discontinued products manual section of their website. Operation is simple enough. Hook up inputs and outputs between preamp and amplifier. The single rotary knob on the front is used to adjust the bass output to the taste of the listener. Asking $200, these sold for about $1500 when new. Comes with the unit pictured and a generic power cord. No original box, but it will be packed well for shipping. Shipping by UPS ground insured to the lower 48. Contact me with any questions and thanks for looking.
