Best Tube Preamp with Biamp Capability


I've received some feedback that biamping using Y-connectors is less than optimal. I'm looking for some suggestions for a tube pre that has biamp XLR capability. Neutrality would be great, but a sweet midrange and solid bass would be second best. Budget: Less than $5k.

The preamp would send signals to four channels of an EAD PowerMaster 2000 which would drive a pair of Revel Studios.

Thanks for you advice!

A used BAT VK-50SE. Very neutral, very dynamic, great bass, all tube, dual XLR output, can be upgraded to VK-51SE.
The Sonic Frontiers Line series pre-amps have 2 outputs per channel to facilitate bi-amping, and the SF pre-amps are known for their neutrality. I can highly recommend the Line 2 and the SE version of it. SF is no longer producing them, but technical support is still there, and they are available used for good prices. Good Luck. Craig
McIntosh C2200 is a great bet - superb tube preamp with MM phono, remote, three sets of outputs (two switchable, one always on) single ended and balanced inputs & outputs throughout. Tape loop, unity gain HT bypass, you name it this thing has got it. And it sounds great! Fits into your budget nicely too...
