Playstion one audiophile stereophile review

After reading review on stereophile on playstation one, I brought 2 same Model number 1001. They sound so transparent and details on vocal that my Sony sacd 777ES does not show. I borrowed different model number 5001 and 7001 from my friends and they sound not much different 1001. The different model number 1001 and others are the RCA output jacks comparing to
proprietary A/V multipin (yellow, red, and white). You should try to buy playstation one and comparing with your CD current source.
