I don't have a hifiman balance card to compare but 901r with Elfidelity and with UFEEL mk5 plays better than hm1000 so of course it’s better to take the 901r since there is the possibility of an upgrade

In cables more expensive than 100 usd, I don’t feel a difference in sound (at least in headphones that do not depend on the cable resistance - hello Andromeda :) ) For me, convenience is important in cables, and here it is better than, for example, in Effect Audio X HiFiGo Griffin, which I also have

excellent cable from Lavricables The cable is soft and the earhooks are also very soft - cable for ie900 / ie600 url=https://postimg.cc/8Jtdq5qv][/url]

no need they have almost the same sound

very soft cable without earhooks

I really like these - Comply™ Foam Ear Tips for Sennheiser

I tried output 3.5, but 901R with elfidelity plays better on any output

I connected the Linum SuperBaX 2pin through this adapter The adapter itself fits perfectly into the recessed MMCX connector

I have Mojo2, and I also compared the 901R (elfidelity) with my L&P P6 for a long time, in the end I sold the P6, since the 901R (elfidelity) plays better

I was surprised that the elfidelity balanced card in HM901R sounds more detailed and with better separation than the HM1000 Red
