Hi everyone , some time ago I purchased a Buffalo 32S dac and the power supplies from Twisted Pair - due to very seriuos illness I haven't yet built it, but I am feeling well enough to Finally start working on my audio hobby again - ( Very Thankfully) , - ( so many people trully take thier good health for granted) ...- - - I have a question , is there a way to bypass any op-amps that are used for the output so I can use a tube output board or tube buffer for the output instead of what is being used now on my Buffalo 32S dac ??? - and does anyone have a diagram to show where to plug the tube output into on the board ? - -- THANK YOU for any help you can give me - Best Regards, hallcon83 - Dean
