Bought in May 2023 and in perfect condition, this amazing R2R ladder DAC/Amp is simple but very effective. It has USB-B and USB-C inputs; RCA, XLR, 6.35mm jack, 4.4mm jack and 3.5mm jack outputs; 2 x 4.4W max output power so it will drive any headphones; and sounds simply wonderful, especially with HifiMAN cans.

I honestly never thought I would sell this baby, I have been in love with it since the first time I turned it on, but the chance to upgrade came my way and I couldn't resist. If you aren't already aware of the EF400 do check the reviews, it is highly praised and rightly so. Some early models had a slight problem with phase imbalance but it was fixed before this one was produced so nothing to worry about there.

It comes in its original box (which will be within a box to keep it looking new) and a power cable with UK plug.
