Reliability? Quality? Sound Quality? Check out Quicksilver Audio. I have had Mike's Mid Mono amps for 6 years, rock solid reliable. Sound great. Just picked up the Quicksiler headphone amp. Forget about the fact it is a headphone amp,it is the best sounding amp I have ever owned.
All Quicksilver amps and preamps are point to point , no circuit boards. He makes a remote pre that is $1500, check it out if you are looking for a fully analog preamp
