I have a preference for R-2R/multibit designs for the reason Mapman mentioned (musical, easy on the ears). I'm very happy with my recently purchased MHDT Lab Pagoda. FWIW, I also have a Schitt Bifrost Multibit, dB Audio Labs Tranquility, and Chord Qute EX. I've used each, with the Tranquility (USB only) being the exception, with my Node 2. I like each of these DACs and have held onto them for various reasons but it's the Pagoda that has a place in my modest system. The Pagoda is but one in their line and perhaps the least romantic. Here's a nice comparison of several MHDT DACs if you care to read a bit about them:

Border Patrol was high on my short list when contemplating my latest purchase. In the end I opted out because it uses a TDA1543 in the design and my Tranquility DAC uses the same chip. I wanted a different flavor so to speak. Best of luck in your search.
