I'm looking for a new amp to pair with either one of the fEarless or BigE cabs eventually (haven't decided which yet). I've tried the Doubler before and while I found it to be very neutral sounding, it didn't work well with my Realist and I found the 3-band EQ very limiting. Seems like the Realist works better with BG equipment. Now that I'm on the Ehrlund I'm thinking of giving the EA heads another shot. I'm leaning toward the iAmp Pro for the super versatile EQ and extra power. My question is, how do the Doubler and Pro compare tonally? Is the pro tuned more for the BG or does it have the same neutral character? I noticed the "passive input" on the pro is set to 1 Meg ohm just like the 1/4" on the Doubler so that shouldn't be an issue and I own the Ehrlund preamp and all three fDeck preamps so I can use those. Also, I only use my DPA for FOH so I don't need the XLR input or phase correction capability. Anyone have experience with the Pro for URB? Thanks.
