Apologies if this is straying a little too far off-topic, but I am posting this here in the hope of catching the attention of members who own both the Bifrost Uber and Gungnir Multibit. I'm going to put my neck on the line and risk ridicule by revealing that in my main stereo system, using SINGLE-ENDED, Bifrost Uber sounds better than Gungnir Multibit. I am in a fortunate position to have an old school amplifier that has seamless switching between inputs with no latency or silences, so I can A/B back and forth between two DACs in real-time, making any subtle differences easy to detect. I will preface by saying that these two DACs are extremely close sound-wise, and that if I didn't have the facility to A/B back and forth in real time, then I would have no hope of differentiating between the two models. However when A/B-ing, Bifrost Uber sounds livelier and more exciting than Gungnir Muiltibit. Gungnir Mulibit is slightly smoother and more laid back, but ultimately sounds slightly distant and veiled compared to Bifrost Uber. Identification of these differences required some concentration, and was made harder due to the fact that Bifrost Uber sounds fractionally louder to my ears than Gungnir Multibit (not by much though, perhaps only 0.5dB max difference), but after accounting for this I remain confident in my findings. I was wondering if anyone else shared this opinion, and had a possible explanation of why Bifrost Uber would sound preferable to Gungnir Multibit? The only logical explanation I can think of is because I am using the single ended outputs, which are reputed to be worse than balanced (sadly my main system amplifier does not accept balanced inputs so I am unable to put this theory to the test). Either that or it is just my ears that prefers the sound of Bifrost Uber. Thoughts?
