I am looking to acquire a Noble Audio Dulce Bass | Sage | Savanna, Audeze iSine20 , Campfire Audio Lyra II | Jupiter, or Westone W60's in exchange for a Gustard A20H with a 4-pin XLR Balanced Male to 2.5mm TRRS Female Balanced Cable, AudioQuest Forest USB A to USB B Cable (1.5m), Gustard Remote Control, and Power Cord. The Gustard A20H is a remarkable and extremely musical DAC/Amp that sounds absolutely sublime with the headphones I own (single ended and balanced connections). I am seeking a trade for my Gustard A20H as I am going to resume commuting and traveling for work. Thus, I will have less time to listen at my home office. The unit has a very minor cosmetic blemish near the logo on the face. The functionality is flawless. Please PM me if you would like to trade or have a suitable offer.
