Border Patrol DAC is "warm-ish" with the standard tube, more so with a Mullard Great Britain EZ80. I primarily listen to analog. I have a analog bias. The Border Patrol moves digital music closer to analog. Can make a CD sound very nice. I also like my Schiit Yggy - decreased warmth but more detail. These two DAC's have turned me off on my Benchmark, Oppo, and W4s DAC's.
