How good is the HiBY RS6? Any other recommendations along this price point?

[pawdiophile]

Hi folks,

I'm using a FiiO M11 ESS Plus.

Have been considering to upgrade to the HiBY RS6.

Couple questions:
1) RS6 owners - what are your experiences and thoughts on it?
2) The RS6 and the flagship RS8 has a huge jump in price point. Is there a huge difference between both?
3) Any other recommendations at similar pricepoints to the HiBY RS6?

Thanks!
