Up for sale is a Audio Research SP-17 L Line stage. This does not have the built in phono stage. I love this product and are only selling to move up the Audio Research lineup. It used a single 'super tube' 6H30 which is rated at 10000 hours, I am not sure on how many hours I have listened but I would guess under 2000 total. This is the current model. It is Black in color. Comes with remote, box and instructions. Conservatively rated 8/10. Freight included in domestic sale. I will ship internationally if buyer is willing to pay for the freight.
