I convinced my GF to buy a lot of Hi-Fi last 6 months. That include her home theatre, so she got my Samsung 9-series 4K/HDR 55" TV from 2015 almost for free, then she bought a 5.1 speaker package on sale incl. the ELAC 111.2 sattelites and their Elac ESP subwoofer and Onkyo TX-RZ720. I been considering to get her a considerble upgrade with Martin Logan ESL (to extend the speaker package to 7.1) and swapping out the center in the package (same speaker) to a true center speaker with from M-L. Then also changing the subwoofer to Velodyne DD-10 plus since the current subwoofer feels a bit dissapointing. I had a great offer at my local Hi-Fi store with a used (a billboard copy in fair condition) of DD-10 plus for 1700 USD. But after some time I thought it is a bit much to just "give away" even it's to my gf. So I considered not doing that... not in a while at least. BUT I also gave her the new over the ear version of Sennheiser Momentum.
Then she bought Bose Soundsport in-ear for portable use, and last week we got the Naim Mu-So QB delivered for her kitchen. She been very satisfied with all those products and is really thankfull to me since I supported her and hand-picked those things. However I used my Asus Essence III DAC (with headphone AMP) as a pre-amp to the mu-so QB using the analogue input. I heard a clear difference between while I had it connected. The difference was clearly better, maybe not by a huge margin but quite clear at least. This quite good sounding small piece of art sounded almost incredibly good for it's size, maybe almost like main mu-so (not qb) but fairly smaller. As I recall the big one had a more lively sound and more entertaining party sound with pressure but this went more pure and more detailed, still having the punch of the qb.
I was thinking MAYBE it could be worth to spend another 900 USD for the Oppo Sonica DAC. So I made a call to the local Hi-Fi store "reference audio" where I'm there VIP customer (been their customer for time to time within 10 years) AND I asked the manager that always listen to all my question patiently. I asked him that I could be interested to buy the Oppo, but he told me the Sonica DAC isn't as good as the Asus Essence III because the Oppo is also a lot Network Player while the E3 is a pure DAC for 700 USD more, that's what you will be paying for and his opinion about the E3, is that it's also quite amazing for it's price point when you have a good match. He also told me the the Oppo Sonica DAC might not do as much as the E3 since it does not provide the same amount of sound qualiy.
This seems very interesting to me and I got curious about it. And here is the thing that makes this post on-topic... Because I was reading Oppo Sonica DAC seems to be a quite good match to Hugo 2 someone says.

Within this context the susvara SHOULD be a good match, some people in this thread and other I been talking to said E3 won't provide enough power. I also got the tip to use the HE-adapter. Anybody tried HE-adapter with Susvara yet!? Any inputs?

People in the thread are telling HE-adapter with a great poweramp performs better than any headphone amp for power. That was for HE-500, but the HE-adapter works out for any headphone and is made for extremly requiring electrostats from Hifiman in mind.
So I was thinking about the Primare A32 but the voltage seems to be too high??
Any other thoughts?
