I mean you can try that, but it doesn’t mean it will have synergy with everything, ideally you want multiple amps. Hmmm for something you could pair for the p6p and drive a wide range of things without leaning one way too far, that’s going to be hard if I don’t ignore the susvara, so I will just ignore the susvara and also keep things under 5k used. I think a mass kobo 394 ii is fairly neutral and drives most headphones pretty well, out of what you mentioned it powers the vc, diana v2 and 1266 pretty well, and the clear, but the arya will imo get a bit too bright on there for my tastes, and it doesn’t have enough for the susvara. A niimbus us4+ (now us5 pro iirc) is a good pick for something a bit more analytical leaning, for those headphones as well). A modwright ha300 will drive all those cans fairly well and lean a bit more neutral warmer than neutral but still pretty great with them, can drive the susvara but again not to the extent I would personally want. The formula s + powerman does drive things pretty well but you won’t be getting the most out of your p6p since it has to run single ended (but it’s still worthwhile), also a bit more neutral warmer leaning. Any of these would be substantial upgrades over using the internal amp of the p6p
It’s really hard to actually answer this question since I really would want to know what the definitive focuses would be instead of just testing things, and also I would want to bump the budget more to around 7k+ if you wanted to go for the 1266/susvara to really take advantage as that puts you in the range of things like a wa33 (actually a good all rounder for the cans you have), egoista 845 (more focused toward the 1266 and susvara), bakoon amp-13r (more focused toward the 1266 and susvara), trafomatic primavera (more susvara and 1266), riviera aic 10 (actually well rounded), etc, and you can continue to get into speaker amps for those two headphones. In my mind with what you’ve listed, the 1266 and susvara would be something I would really focus on and ignore synergy with some of the other headphones, as those two are the most needy and things like the vc and diana v2 are more forgiving when it comes to amp pairing so that would be where I would make your compromises
I mean compared to other portables? Compared to a desktop line out as dac? Driving headphones or iems?
I mean as a dac, I’ve already kinda pitted it against something like the holo spring 2, so dacs similar to it’s performance I guess would be it’s tier, it’s not going to compete with a lot of the dacs I like around 5-3k used with things like a lampizator amber 3, aqua la voce s3, berkeley alpha series 2, some of the audio note/sq1x dacs around that range, the sonnet morpheus or higher end metrum dacs, the rockna wavelight, bricasti m3 or m1, msb analog dac, merason dac-1, xi sagra dac, lessloss echos end and the list can go on. It fits well into the 2k range of dacs with things like the yggy a2, dangrous music convert 2 or burl b2 bomber, mytek brooklyn with psu pgrade, benchmark dac3, bryston bda-2, wyred4sound dac2 variants, etc with most of these it trading solid or some blows, or fairly outperforming overall things like the soekris dacs, the denafrips pontus and ares ii, holo cyan, mhdt dacs, older benchmark dacs (honestly possibly current one as well), auralic vega, etc. I’m really just spewing out names here which isn’t going to be really helpful, as it would be much more helpful to just compare one on one as that would give you a greater sense of how it actually competes
It’s just hard to give you a meaningful answer without some sort of focus and direction
