Les, I have a LokSound V3.5 for my Baldwin diesel switcher and I think it is excellent. The motor control of the ESU decoders (LokSound and LokPilot) is second to none, especially at low speeds, and I never had any problems with programming. Bearing in mind what is possible with such a tiny speaker, the sound of my Baldwin is very good compared to movies and sound files of this engine I found on the internet. There are some complaints that the horn of the LokSound decoders is too weak, but it is not a problem for me, because I think the overall sound of the decoder is too loud so that I turn it down and leave the horn as it is. LokSound is the only manufacturer to offer sound decoders with Baldwin sounds, so that I cannot compare it to other sound decoders, but you definitely won’t get junk when you buy a LokSound decoder.
I just ordered another LokSound decoder for my Alco S1.
