BeePre output questions

[Alonzo]

Okay, so it's time to change out some of my equipment (just cause it's been sitting comfortably too long).  So I have music playing (Bluesound to Gimby DAC to BeePre to Stereomour) and I start to unplug some of my equipment.  At the BeePre, when I get to unplugging the RCA's from my SS amp (Schiit Vidar) the Stereomour gets louder.  So I do the normal thing and plug it back (volume decreases), unplug (volume increases).  I repeat this with the Vidar inputs to all of the BeePre outputs ( I have 3) and it's the same.  The Vidar is 47K input impedance, is that driving down the output of the BeePre to the other outputs since they are tied together?  I do not have a balanced output, 3 unbalanced instead.  Anything I can do to fix this?
TIA,
Alonzo

The output impedance of the BeePre is the upper leg of a voltage divider with the components it drives. 

The output impedance of the BeePre is about 600 ohms (603 when I last measured one), so we get:

BeePre driving Stereomour is a 600 ohm resistor in series with a 50K load, this causes 0.1dB of signal loss.

BeePre driving Stereomour (50K) and a Vidar (22K) in parallel will cause 0.33dB of signal loss.

There isn't anything to fix in this situation, this is just the way things work.

Thanks for the lesson Paul.  Luckily there's plenty of range left on the volume knob.
