I will listen to the sound before making the update decision. In the 1990's and early 2000's DCC O scalers had few choices and I installed paired electronics to get the power I needed and some basic sounds. The approach works but to my ear doesn't capture the sound variation between units starting a train, or notching to climb a grade with a heavy train. Today we have several 3rd generation higher power integrated sound/power/lighting decoder choices that in my opinion far out perform non-integrated sound/power solutions. Yes it does come at an added price - but as with levels of detailing, prototype fidelity, and build quality in our models we all get to make our own trade-offs.
Still looking to hear from others about their experience with Dallee sound systems. From the Dallee web site I learned they can be installed in 3 rail AC or 2 rail DC locomotives with sound controlled by a special box. Has anyone done that?? If I do decide to remove the electronics I know there is a market for used D408sr decoders - don't know about Dallee sound modules.
