I love my Little Dot (same model). It flies under the radar of most people because it's less expensive that some Hi-end types of headphone amps; I think it has one of the best sound presentations I have ever experienced--imagine how much you would pay for an OTL power amp of this quality sound in a 'normal' room system? It's a clean and clear and atmospheric sound that is utterly non-fatiguing. Mine has been very reliable and gratifying (yes, using Sennheiser 650 headphones, no impedance/driving issues). I have also used it at length as a single input valve preamp in a second system (my son-in-law is using the Mk3 like this for a year now) and it's not embarrassed to be in the company of most other valve preamps I've owned. It's a tube-roller's dream, and there's a large Forum for this on the Little Dot website, but I like your current configuration anyway.
