Rich,
I went to the Border Patrol, Volti, TWL room and was amazed at the sound. The Border Patrol amps were fantastic, the Volti Rivals were smooth as silk. But the thing that tied them all together was the Border Patrol DAC.
The Border Patrol DAC is one amazing sounding DAC. They always say the weakest link and that DAC was no weak link. It brought that whole system together and made it sound fantastic.
I purchased the SE version with USB and SPDIF and it displaced my Schitt DAC in my system. It is smooth and well refined. I have heard many highly reviewed DACs, Brooklyn, Schitt, etc. and this little guy can stand right with them. Tube rectified, single ended strait signal path, no oversampling. Clean, simple and uncomplicated. As Dave would say, "Do no harm".
I run my CD and computer audio through it and it delivers what I want to hear. Very happy with it.
