I recently bought an RS451, primarily for the headphone function. I connected it to my RD160 DAC via USB today and am very happy with the result. I think the RS451 is going to replace my current transport, and I also don’t need a pre-amplifier anymore 
We are very pleased to hear that you are enjoying the results when connecting the RS451 to your RD160 DAC via USB. It’s especially rewarding to know that the RS451 may replace your current transport and that you no longer feel the need for a separate preamplifier.
The RS451 was designed to deliver high-quality network streaming performance while also serving as an excellent digital transport and headphone listening solution. It is great to hear that it is integrating so well into your system.
We hope you continue to enjoy many hours of music with your RS451. If you have any questions, suggestions, or feedback in the future, please feel free to share them with us.
Thank you for your support of HiFi ROSE.
Best regards,
Thank you so much ROSEHAN!
I have a suggestion. It would be nice if there were a function that allowed me to turn the trigger control automatic off with headphone listening. Currently, my power amplifier stays ‘on’ when I listen with headphones, even though the speaker output is off.
With regards,
