I'm leaning toward a 210 combo to use with or without my 8 ohm JBL 115 (K140) cab. I would like warm growl with articulate mids and highs and full bottom. I may also want to call my SVT 810 into action and switch out the 210 or 115. I can not possibly compare these four combos in the same space. The Eden Metro offers the dual pre-amps (tube and SS). The Ashdown ABM-C210H-500 has the subharmonizer, which many seem to like. The SWR Super Redhead has some nice ease of use features and has also recieved many favorable comments. Similarly many prefer the Aguilar sound. Putting cost aside for the time being, what are the compelling arguements to help me drive my decision?
