If you love amps, there's more than one: LSR&D Superamp monos, Meridian 105 monos, Acoustat TNT200/120, G.A.S. 500, Bedini 100/100, Sunfire Signature 600-2, BEL(Brown Electronic Labs), Perreaux 2150b/3150, to name a few. But imo, the holy grail would be non other than the elusive Yamaha MX10000. Haven't heard nor seen one except on the net. One came up for sale on CAM a little while ago. Like the Scarlet Pimpernel, it appeared and then disappeared without a trace! Wonder what happened there?
