Vocal preamp comparison (Api 3124+, Chandler Germanium, TLA valve preamp

[acappa]

Hey! I´m working on my first brutal death metal album, and I´m not very familiar with those low end gutural voices and had no idea which preamp would suit the best...so I made a semi professional shootout, I hope it helps you if you´re about to buy one of these.
As I could only try two preamps at once I make the first shootout and I took the winner (or the one I liked more) and make the second. Mike was a Shure SM7b, here you can listen to the files:

First trial: API 3124 Vs Chandler Germanium
Second: Chandler Germanium Vs TLA Classic Tube Pre

For all interested, I ended up using the TLaudio, using the drive pretty hard plus distressor in dist 3 mode. What´s the best sounding in your opinion?
