Amp & headphone amp plugged in simultaneously?

Hello gentlemen, I couldn't don't a solution so I'm asking...my dilemma.  From my preamp/dac (amr-dp777 I tried XLR into my main amp (plinius) and then RCAs into my headphone amp (topping a90) and vice versa.  I also tried rca splitters at the preamp.  When any of these happen my headphone amp gain is substantially reduced.  I take it I'm reducing the impedance even though the plinius is off?

What I'm trying to to is avoid having to unplug the plinius everytime I want to use my headphones, surely there is a solution short of buying a dac/preamp what also serves as a headphone amp?

Thank you for your time.

Just use the Plinius as the headphone amp.
Buy some speaker adapters here, tell tell to make it for your amps binding post & plug them inhttps://www.ebay.com/itm/Balanced-XLR-to-Speaker-Taps-BANANA-PLUGS-Hifiman-HE4-HE5-HE6-HE500-adapter/172733761468?

I don't know what I need, I have LCD2s which work find as soon as the plinius is out of the equation.

Sure you don't just need lower impedance cans?
I run balanced from DAC to pre and single end from DAC to tube headphone amp.
9:00 balanced and 10:00 balanced to Quad cans LOUD

Hi,

Weird this happens with high input impedance amps, unless the XLR output is getting grounded or something like that.

Best,

Erik
