If you want basically 0 compromises yes I agree with currawong you should get separate dac and amp, if you want the best of the best on what AGD can offer id Rec R-7HE Mk3, HE-9MK3 and DI-24HE and ACSS cable, but thats imo is something you would buy if you have the susvara, the R-27HE its basically "End-Game" for everyone, or if youre going that route you can also consider Holo Audio offering, Because Im very aware the Bliss is capable driving the susvara and so does the Master-9P but on the M9 you will be driving susvara run off speaker out.
Just like currawong said unless you have the money and space you can consider R8 stack like you've mention or if you're a straight up baller go all out with R-7HE route, but for me personally since I tested my speakers Audiovector Qr1 with R-7HE MK2, R-27 2021 and Master 10MK2 amp, It made my speaker sound like studio monitoring which yes its insanely resolving but I find it boring. Hence I decided to get R-28 despite loss is resolution and soundstage but boy the R-28 the tunning is too die for. One of the most fun sounding and engaging yet resolving dac I have tested so far.
The R-27 2021 on headphones however, I really really liked it on headphones and thats something Id probally buy when I make more money along side hopefully TOTL headphones.
And I think all of us can agree here once you start going into r27 and above this is purely point of diminishing return and all we care about is chasing the absolute last bit of sound performance.
Imo you should be asking either you want to spend that much to get a small performance increase/perfection or you just want to be done, because coming off from R-27 2021 + DI-20HE combo, for me at least on head-fi thats "end game", the only thing that I would upgrade is the amp for Susvara, The 27 2021 dont have the juice to drive susvara.
That deff will change once I get to try R-27HE, Holo Audio May, Denafrips Terminator and MSB. But for the general people unless youre an idk an oiler the R-27HE itself is overkill.
