Let's try again... I'm looking for a versatile amp that can handle two good, but contrasting headphones, an RS1 and... something much lusher, yet to be determined, but similarly top tier. Ideally it would serve as a pre amp also, but DAC is already taken care of. I'm attracted to tubes, which may benefit the Grados, but I'm concerned about their impact on the other pair of cans. Budget up to around $600 unless people think I'd be underproviding for the headphones at this price. I know it's difficult without knowing what the 2nd pair of phones are, but they'll be the subject of another thread in the headphones section, and as I said I'd like them to contrast quite significantly with the Grados.

In that price range, I'd consider the WooAudio 3+. Very nice amp, and it can handle the 32 ohm impedance of the RS1. Lots of tube-rolling options too.
