A headphone outlet question for Magnum Dynalab 208

The MD-208 does not have a headphone output.  Is there a good quality device/box/connector that allows a headphone out and speaker connections without a sonic downside?   Thanks,
I’d get a headphone amp with a volume control and connect the tape out from the MD-208 to the head amp’s input.  I believe this should allow you to operate the speakers and headphones independently as the tape out bypasses the receiver’s volume control.  Hope this answers your question.
