recommendations for amplifier to use with Voyager?

I have a Voyager RME , and I usually run it through the MF-104Z Analog Delay. I am interested in an amplifier that would be ideal for small venues, lightweight and highly-portable, within a price range around $300 or less, and would sound as good as possible within that price range with the Etherwave theremin and Voyager. Do I need to use a keyboard amp, or would a guitar amp be suitable? Most of the time I would probably use my Voyager in mono, because I do the right output into external audio in trick to fatten the sound. I am looking for an aggressive sound. Much of what I do is in the free form electroacoustic improvisational experimental noise style. I use a lot of frequency modulation and have recently started using the HP/LP Filter mode instead of the Dual Low Pass. Some lower-priced amps I have looked at have spring reverb, which I am interested in. I am not interested in amps that have amp modeling and digital effects.

Look at any of the Roland KC series…for small amps they put out tremendous sound.

Id use a keyboard amp because the Voyager and the Theremin are capable of so many extremes in Frequencies…especially with the 104 because it will definately generate some speaker blowing highs.

I really think that ROland has some of the best stuff around…second to Moog…probably as its always been heheh.
