    Item was packed safely and shipped promptly. Item tested and played as described. I feel like I got a fair price for the item. The item did not work out for me with my equipment. Seller was gracious and fair working with me & my situation. I would 100% buy from this seller again. They are an asset to Ebay and to the audio community, as well. Purchase with confidence.
