I'm reconfiguring and looking for an alternative to supplement my Streamliner 900. This is a great amp, and I'm highly pleased with it, but I'm having problems getting the clarity? hi freq response? articulation? I need in some musical situations that are different than what I've spent most of my life playing up to now. I guess I'm needing something that some of you might call a more hi-fi sound, but I've never been accused of hi-fidelity before, so I'm not actually sure what this means. I am not looking to replace any of my current cabinets, as I am very pleased with them. I need to be able to pair the new head with several different cabs depending upon the venue and the combo. Each cab has its own challenges related to resonance and frequency response, so flexibility is important: Revsound 2 x 8, Revsound 2 x10 and one or two Ampeg SVT 115e's. The two subject heads are of interest because of the manufacturer's reputation, the eq (the Mesa in particular here, since it allows for parametric tuning of two mid bands which I'm thinking might be very useful for the 8s and 10s), and because of their ability to drive to 2 - 2.6 ohms. Any thoughts or advice?
