Has anyone ever used a ShuttleMax as strictly a power section with a Streamliner (I'm looking at the 600) as the preamp and EQ? I've been looking for a warmer, all tube amp-like thickness to the sound, but want to retain the 1200W capacity of my SM...the Shuttle Max 12.2 with 2 Aggie SL112's are nice but not as warm and thick down low as I'd like...I thought about changing the cabs to ML112's (or just adding an ML112 to the current rig, making it a 3x12), but that would prove more costly for me (I'm not US based) than adding the streamliner to the chain. Couple additional questions: 1) Which road would in your opinion yield the thicker sound I crave: change the cabs, add an additional cab (ML112), or combine the Streamliner and Shuttlemax? If you vote for 'other', please give an alternative solution. 2) How would I rig this exactly? I'm guessing to take a XLR to 1/4" cable and run from Streamliner DI out (post EQ, line level) into Master receive (power amp IN) on the ShuttleMax. 3) Do the power sections of these amps significantly contribute to the overall tone and if so, are both power sections identical? I'm talking about the Streamliner's 600W Power amp compared to one amp from the SM 12.2 (also 600W).
