If you are choosing your DAP based on a jitter spec or some other measurements which don't involve the actual listening with high res files and TOTL high res monitors, then go by the numbers

Of course my opinion is subjective and based purely on my ears and extended review experience of products sent to me by manufacturer for testing and comparison. BB is legendary, no doubt about it, but you have both LPG and X5ii rocking 1792 and one is summit-fi while the other one is mid-fi. The same dac with a quite different dap performance because of amplifier stage, analog/digital circuit partitioning, power filtering, layout, and selection of other components. I love both of these DAPs, and if anybody noticed - I keep flipping them in my sig, fighting for the top spot. Or, and if we are talking about best BB implementation, Micro iDSD beats them all
The bigger question here, has LPG been discontinued completely or what's going on? I haven't been able to get in touch with my Lotoo contacts/reps, Dignis decided not to make any more cases, their official US Amazon store/seller no longer lists any new units, and even Ken dumped it from ALO website. If you ask me, and it's just my guess, I think they are done with a current model production and perhaps ready to surprise us with <
wishful thinking> something new <
/wishful thinking> ?
