Hello, I have just tried the Lundahl LL1676 input transformers (1:2) in my DIY headphone amp to raise the gain. It works but the lowest bass has gone south. Is it the 100k volumpot after it that is the problem or is it the output impedance of the source?

You will have no low bass for the first several hours of listening after installation due to residual core magnetization. Connect the source and run it at a high level overnight and you should hear a dramatic improvement.

Thank you for the answer. I have tried a little "burn in" but maybe the input level has been to low and the hours to few. I will keep them running for a week and see what happens.
