Hi Rob,

With 8K2 across the o/p of the S&B's and (presumably) 47K on the mm input of the Borbely BBV is currently presenting maybe 69 ohms to the EMT. Reducing the load resistor value further to perhaps 5K would reduce the load to the equivalent of what it was with your WAD ie 45 ohms (ish). This may tighten the bass up quite considerably but may also begin to shut in the hf aswell. However there is room for a little adjustment of that with his load capacitance.

The only answer with this is to try various values of resistor to get it right. It took me quite a while to get the value I was happy with with my cartridge and transformers. I haven't listened to the S&B MC transformers in isolation so can't really comment on their absolute quality.

Is the WAD circuit very different to the EAR 834?
