My Spectrum USRA 4-8-2 Mountains (2) stalled on the frog of some of my Walthers Shinohara DCC friendly turnouts. Bachmann was kind enough to exchange the Mountains for Consolidations, which have no problems with the turnouts. Now, unfortunately, I find the Tsunami sound in the new Consolidations is much 'tinnier' and shallow-sounding than the Tsunami sound in my older Consolidations. I've looked at the sound install in a new and an older tender and can't see any difference. I've reset the Tsunamis back to factory defaults with no improvement in sound.
