High grade tube pre with digital display
I am using a Modwright 36.5 LS/PS and am very happy with it. However, I am reconfiguring my system and will end up using the same DAC (PS Audio perfectwave) for my MCH and 2 channel system, using a processor in the chain that sits before my DAC. So I basically need to use the same input on a preamp at unity gain (for multi channel mode), and to control volume in stereo mode. This is easy to do but requires a step attenuator and digital display to read the volume level setting. The Modwright cannot do this, so I need to change pramps. What top notch preamps at or above the level of the Modwright are the main contenders? I need fully balanced, and remote control. Preferably not a space heater. I am aware of:
Audio Research Ref 5
BAT (Rex or 52)
VTL 7.5 or 6.5
Any others I should consider? Any comments on the relative quality of these contenders, considering the Modwright as my "baseline" performance level.
