If you are handy with a soldering iron you should consider the Raleigh Audio "Mood Indigo" line stage kit, available from K&K Audio. You can read about it in the current issue of AudioeXpress. $1800/kit. It is a balanced differencial design that is transformer coupled; both input and output. The output topology is a parallel feed design that uses CCSs to isolate the audio signal path from the power supply. It also uses a unique power supply design that uses a CCS to illiminate the need for large electrolytic caps plus a tube rectifier for good sound. Includes remote for volume and muting.
