Trying to add Topping LA90D amp to Topping A9D preamp
Any help would be appreciated...I added an amp to my streamer, dac, headphone amp/preamp system and am now not getting any music through the headphone jacks on the preamp - the specifics: Wiim Pro Plus - optical connection to - Topping D50 iii dac - TSR to XLR connection to - Topping A9D headphone amp/preamp (all worked fine as a headphone amp until I tried adding:) - XLR connection to - Topping LA90 D amp. Amp switches are set to bypass, stereo, low gain. In this configuration, I am not getting any music to either my SE or XLR headphone jacks. I made sure I switched the A9D to "preamp" and "xlr" modes. I have no idea what I might be overlooking or missing...any thoughts would be deeply appreciated! Thank you.

Also, when the INPUT button is fully pushed in, is that the balanced or single ended input?
Thank you!
