A basic DI like a RedEye or Demeter doesn't do what a proper preamp does. Most of us need full EQ, FX loop, notch filters, flexible in/outs, variable input impedance, and footswitch muting control.

When you buy a Grace Design Alix for $600 it's because you need/want all of those things combined with a studio grade input stage. And yea.. you really do hear it if you have good amplification. If you want those things with dual source without a drop in sound quality you get the Felix for $400 more. The current alternative is the next tier down in fidelity or going to studio gear. Problem there is it's not designed for a performance environment meaning it won't be all that sturdy, light, compact, or flexible. Or you can do what folks did before we had the Alix/Felix and get a Pendulum SP-1.
