Sounds the best in balanced so anyone looking for a decent balanced amp around this price range, its a fantastic choice. Plenty of power to drive planars like the Arya or the Edition XX
HankhoI think overall the SE output of the LCX is pretty poor. So for something like an Arya, I would definitely recommend a Balanced XLR cable for this specific amp
HankhoI bought mine off Amazon (new fantasia I think?) It's reasonably cheap and does the job but is pretty microphonic. Or you can get some from known companies like hart audio cables or periapt and so on. Jus take sure you get the correct cable for your headphone (newer hifiman use 3.5mm connectors and some older one side 2.5)
