I've got three of Roy's (Keytes ) sound decoders installed. With a fourth on order. Two I bought seperately and installed myself. The other two Roy fitted / is fitting, I'm new to DCC sound but I was comletely sold after I got the first one. He gave me advice on in which I good fit the larger speaker and on the Pannier he even emailled me a set of instructions on how to install the decoder ( it's tight!)
I'm no expert on the correct loco (steam) sounds but all I can say is that they add a whole new dimension to my layout
You can ring them direct at their shop, could be worth having a chat
