This does look interesting but I'm not sure it would be a step up from what I already have?
I am currently using an Echo Layla 3G and have an ART MPA Gold, M-Audio Tampa and DMP3 for my pres. I'm then using an SM Pro Audio M-Patch 2 as my volume controller.
If I were to go for one of these I'd have to sell all of this to get it. Not sure if this would be a good move
