Just a quick note about the Rattle The Lock album above.
I've listened to this album quite a few times on my system in the past 6 months or so. I just flipped over to Side 2, Track 1. The bass in this song "In Any Tongue" is absolutely amazing! I have never heard this cartridge or this album reach to such depths before. This has to be due to the BillD C-1 and that new 2134 opamp. Holy smokes!
I played this album a little over a month ago with the Halo P5 and M-500t MkII, and it didn't have anywhere near this kind of deep bass. That says a LOT for the BillD C-1 and its built-in phono stage. Now with the Lounge Audio phono stage with the P5 and M-500t MkII, it managed very deep bass as well, but not as pronounced.
Man, I'm loving this C-1!!!
