the lps mod on node 130’s make the analog section sound better, for sure -- more clarity, micro detail, dynamics, where the stock unit is inoffensive (a good thing) but rather bland sounding
i will pick up a new node x at some point, i suspect it will have the trademark sonic traits of the ess chipset... with greater treble forwardness, prat and finely etched detail with some foreshortening of the soundstage ... definitely a smart move by b-s making the change, as it cures the main sonic ill of the n130 dac performance
i think the other big plus is it is a better unit for headphone listeners... but used as a streamer feeding a separate downstream dac, i don't think new one will do a meaningfully better job
