3, 2, 1.
Source 3 sounded the most balanced across the spectrum to my ears. Nice highs, mids, and lows.
Source 2 sounded similar to Source 3, but was lacking a bit of the presence that source 3 had.
Source 1 sounded the most unique of all the sources. It didn't sound bad, but I liked it the least of all three. I think it has to do with how the vocals sound on this source. Overall a warmer feeling to this source, but there is still something that I'm not crazy about.
