Another Cayin Audio<\/a> amplifier that lends you multiple variety.\u00a0This mid-tier EL34 HA-6A with the top-tier sound gets praised by John Grandberg on Darko.Audio<\/a> for its multiple flavours and way of excelling with all of them.<\/p>\n

The ability to roll between EL34 and KT88 power tube variants is special in the world of tube headphone amps.

Depending on your power tube choice, HA-6A has the ability to dump up to 4.5 watts per channel of pure Class A power into your cans, but that’s just the beginning of the story.<\/p>\n

Large EI core output transformers\u00a0built in-house to Cayin’s spec means it’s not just brute force but also finesse ensuring great, clean frequency extension at the bass and treble extremes \u2013 otherwise\u00a0a weak point in other tube amplifiers.<\/p>\n

Meanwhile, a loosely wound EI core power transformer ensures greater AC line performance over a conventional toroid, avoiding saturation plus the negative impacts\u00a0caused by the latter’s high magnetic flux.<\/p>\n
