I purchased a Technics Integrated Amplifier that is digital, so this is collecting dust to my broken heart. I must move it on to a new audiophile who can enjoy this wonderful DAC. Has been trouble free. Comes with two tubes with low hours, one is a Telefunkin and the other is a Tungsram, both EZ80 has two SPDIF (Coax) inputs and RCA outs. This retails for $1,750.00. I asked that no cord by shipped with it because if youre going to spend this kind of scratch on a DAC, you have an upgraded power cord to go with it. There are numerous reviews on this unit that are glowing. It is an amazing piece of hi-fi, and you can get it like new for a lot cheaper than buying it direct from Border Patrol. Have original box, will ship in that with another box to protect it. Thank you for looking my feedback speaks for itself. Will be insured and packed like Id want it to arrive safe to me. Natural, sweet, open and organic are not words usually used to describe digital electronics but those were the design goals for the BorderPatrol DAC. Too many digital audio products sound processed, unnatural and un-involving and this is particularly true of many of the new generation of hi-resolution delta-sigma DAC’s.The BorderPatrol DAC uses a R2R DAC chip with no over-sampling and no digital filtering fed from a very sophisticated choke input, tube rectified power supply to produce one of the most natural, ‘un-digital’ sounds it is possible to hear.Many owners have said this is the first DAC that they can listen to for long periods without irritation or fatigue and that lets them emotionally connect to digital music for the first time.Several vinyl diehards are now happily streaming and playing CD’s after previously giving up on digital audio.This relatively low cost DAC is equally at home in affordable audio systems or in esoteric systems such as the BorderPatrol/Volti/Triode wire labs systems costing tens of thousands of dollars that it frequently finds itself in at audio shows.
