Ive just been playing with my new Precision Craft Models EMD E7 with Loksounds factory installed. I can say that it blows away the competiton on N-Scale sound. Too bad I model modern era and PCM only has older stuff so far. I paid way below retail for it but Id pay the $200 retail each to replace my fleet I have an Intermountain SD40T-2 Tunnel with the MCR1636 installed I have 2 Kato AC4400 with the MCR1644s installed. These can not be compared to the PCM. I think ive bought my last non-sound loco. By the fall every loco will come preconfigured with sound. Seems if its engineered-in you can get much better quality. My 2cents. Your thought?
