I remembered my initial impressions of the 751's reproduction - initially sounded neither here nor there. After a few days, the 751 started to sound right. A couple of weeks later, the 751 reproduction was actually quite decent. Only issue I had was the clarity of HF - details were not forth coming as the SL6S ... probably due to the plastic dome protector on the tweeter as per the Mission 753.
Since I had the SL6S, I decided to let my go of my surplus and sold the 751 with the Pioneer A400, Pioneer F-225 and the Rotel RCD-965BX as a package to a friend.
