I am the original owner of this outstanding EAD Signature 8 Preamp Processor. It was originally an Ovation + and was upgraded to a Signature 8 through Alpha-Digital (a $1,750 upgrade). This allowed me to enjoy all of the latest Blu-Ray sound codecs through the analog outs to my Oppo Blu-Ray player. Some people claim that this is better than HDMI. I always used Tara Labs Air 1 interconnects and the power cord was upgraded (a $50 upgrade). All this produced excellent results. Everything is original including the box, remote and instruction booklets. Receipt for the $1750 upgrade is included. I will also include a Tara Labs component cable worth over $150. Asking $850 for everything. I rate everything conservatively at 8 out of 10, mainly for age. Everything is in excellent working condition, no scratches that I can see. If you know EAD, you know what a quality unit this is! I will back this up 100% for 30 days if you are not satisfied. This unit sounds as good or better than units costing thousands more. Will only ship to lower 48.
