Don’t overthink it. The Clears are very easy to drive. Test them on your Rodecaster Duo and if they sounds good, save the money.
If you really want a dedicated DAC/Amp something on the cheaper end like the JDS Atom stack, Topping DX3+ or JDS Element will be more than enough for this and the vast majority of headphones in the market. IMO it’s only worth going more expensive if you’d like additional features like a RME ADI-2.
