Blue recomends a robbie tube pre with their mic. I wasn't sure about posting on this topic, I have a baby bottle and I am using a presonus tube pre. Cannot say that I am in love with it-but I have a lot of issues-and I am assuming the $100 tube pre is one of them. I have a cheap mixer, I am recording with a unit that has guitar plugs for inputs. I also think that my vocals need work-it is one thing to sing somewhere, but recording may need a lot more polish. I have used three different mikes on my recordings-I am trying to lisen carefully to the different vocals.
I could not mic my guitar or keyboard with a dynamic mic(I had to plug in directly to the unit)my baby bottle does a WONDERFUL job on recording the instruments. Very happy. Not sure if a $999 tube pre is going to fix my vocal issues. It could-but could be a very expensive experiment.
Real good idea you have trying to get some advice before you leap!
I bought mine at guitar center. Think you can buy online from them.

Simplicity of design. Purity of sound. Robbie is Blue’s Class-A discrete tube microphone and instrument preamplifier. All of the technical quality and design innovation that goes into our line of award-winning microphones has been engineered into making Robbie the finest tube preamp available today. With no ICs and only the highest-quality discrete components from input to output, Robbie is one of the quietest (-131 dB EIN @ 50 ohms) and most detailed (THD 0.006%) tube preamps available today. It features audiophile-grade ultra low noise metal film resistors and polystyrene capacitors, and provides the user with the best of both worlds: an electronically-balanced, fully discrete input stage, tube gain stage (ECC88 twin triode), and an electronically-balanced solid-state output stage. There is no switching crossover distortion anywhere in the completely balanced audio signal path. And if that’s not enough, Robbie achieves and amazing 34dB headroom before clipping! Designed from the ground up, this
limited production mic pre is like nothing else commercially available today.
