I believe you mean 6N1P. As far as I know, no one else is making that tube unless you can find a cross for a 6N1P.

The 6N1P datasheet states that it is similar to the 6Dj8/6922/E88CC (which are equivalents) - except for the higher heater current (2x higher for the 6N1P). A look at the data sheets shows other differences, so I'd stick with the 6N1P if that's what was specified.
All these tubes were designed to be low distortion and linear from the outset - which is not always the case with tube design. Perhaps this is why people refer to them as SS like? Those who prefer euphony to accuracy probably won't 'like' this tube - which is ok.
