Info given on this site as any other needs to be taken with a grain of salt. The OP says that the Teddy Pardo LPS would be a good recommendation for the Bluesound specifically if you use its internal dac. Well, I got the absolute opposite recommendation from someone who was highly knowledgeable with the technology and explained it with technical jargon that went well above my head. What he says is upgrading the LPS on the Bluesound if using its own dac is a waste of money due to the configuration of its dac, but highly worth it if using an external dac. He also mentions examples of high quality dacs with external LPS, and the difference in cost when they sell their dac with internal or external LPS to explain why the Teddy Pardo cost vs value is so high. I use the Gustard X26 PRO dac and am very pleased with upgrade in clarity and sense of space. Sometimes I just have to put my two cents in because info given here can take you right down the rabbit hole :)
BTW, I owned the Aries 2 also but the Gustard beats it plenty, even for an analogue fan as my system demonstrates. Not sure about that R2R thing. It was highly recommended here and is another example of advice I could have done without. However, overall, it still has been a good education to research stuff here but no reason to dive all in on anything specific you hear without backing it up through further research. So many sites, so many opinions...
