Very nice unit. Listed as 8 only for age. Otherwise it is pristine. I cannot find a mark on it. I don't have original box but it will be shipped in an Audio Research PH-8 box. I used this unit with my second turntable and a Lyra Delos cartridge to a line input on my CAT SL-1 and it sounded terrific. Nice pace, detail, tonality and tight bass without being bright. I am selling only because I have upgraded to a much more expensive phono stage. PayPal only. Sales and shipping only to US lower 48. $45.00 shipping. I have 100% positive feedback for over 200 transactions on eBay. And 100% positive feedback on US Audio Mart.
