All Esoterics have a slightly cooler rendition. Depending on personal taste and a system context, it may sound "mechanical" or just "accurate". But if you like your D70/P70 combo, there is no reason you shouldn't like the X01.
Since getting the X-01 would meen that you also need a preamp, I would suggest getting a preamp first and trying it with your combo. If you find it beneficail (sound wise) you may sell your D70/P70 for X-01.
