If you are running ESLs it is the nature of the technology that you will have to run tubes for best results. ML has set up the speakers at a low impedance in an attempt to make them work with transistors, but it is only half successful as you still deal with a dry coloration that is inescapable with most transistor amps due to the characteristics of the speaker (including the impedance curve).
The way you drive the speaker with tubes is to use an outboard device called the ZERO. This is an autoformer that is set up to allow a tube amp to be optimally loaded while at the same time being able to drive a very low impedance load. It would be nice if ML offered a higher impedance tap so that both tubes and transistors could be used...
