If you're reading this, you know about this unusual (battery powered) and legendary DAC. If you want a NOS DAC that delivers [B][U]TONE[/U][/B], this is the one for you. I've had this one three years and it has all the options available except optical input. List price is £1,600. Selling for £900. Wheathampstead, Hertfordshire I also have a yellow top Optima batter I'll be selling, if you're interested. Thanks for looking!
