Leog2015 Hi.
I love what R2R Ladder Multibit dac's bring to the music compared to Delta Sigma dacs, they have a jump factor and body to the vital lower midrange compared to Delta Sigma, which are sweet and smooth but to me boring to listen to, especially on Redbook CD's.
I would strongly recommend a good listen to the MSB Signature DAC IV because as they say on their website it has a " Platinum Signature Ladder DAC" as their D to A convertor.
Cheers George
