I bought this a year or so ago to play with after Jerry recommended the version with added USB input. It's a decent little thing, powered by internal 9v rechargeable battery. It's not something that I need, since the Lyngdorf amp negates the need for a DAC, so it may as well go to a new home. They're currently £165 on eBay - see https://www.ebay.co.uk/itm/Non-Overs...T1JF:rk:1:pf:0
These DACs are not supplied with a charger, but Starting Point Systems state in the eBay listing that any 12v DC adapter is suitable, and that's worked for me.
I would like £65 for it, posted in the UK (international extra)
