Heyanming, I am very fond of JRDG products, but confess of having very little listening experience with Plinius. Yet, regardless of my lack of experience, your question remains somewhat difficult to answer. Even within the same product line, the sonic signature has changed over the years. E.g. JRDG legacy products were a little warmer sounding than today's line up, with a little less bass control for speakers exhibiting difficult loads. . . . new JRDG products sound as 'liquid', but are more open, transparent, and with enhanced bass control. I do like the newer JRDG sound a lot. . . so, it is 'better' to me than the old sound. But 'better' is a term relative to my own particular preference only, not an absolute that will of necessity be valid for everyone else. Currently, the JRDG integrated lineup has 2 products: Continuum 250 and Continuum 500. The 500 has twice the power of 250, but also has incorporated Power Factor Correction (PFC) power rectification and buffering in the input stages which yields enhanced low level detail and 'sweetness', as well as a bank of bulk caps in the output stage to enhance authority. Whether or not Continuum 500 is preferable to a yet unspecified Plinius integrated will be a matter of personal preference, based on listening habits, and specific categories of issues peculiar to individual listeners. Sorry I could not provide a more straight forward answer. Guido
