A very useful adapter to have for connecting speakers with RCA jacks to your laptop's headphone input for great sound, or to connect your laptop to your stereo using the headphone input on your laptop/computer to the RCA jacks in the back of your stereo.
Bought this to connect to my tube headphone amp., splitting to the headphones and the second to the power amp. Results are good as expected. The convenience of not having to disconnect one or the other for switching modes.
PROS: Convenience for any pre-amp.
CONS: Splitter output connections are too close together. Otherwise works
