Squeezebox Touch vs Transporter

How about the sound comparison between the Transporter and the Touch?
The Touch is excellent at the price point, but my Modwright Transporter (highly modified) was more refined and more revealing with better separation. I never compared the stock unit though, so could not comment. I think the Touch is a real bargain for the sound it delivers. I was using it with an aftermarket power supply in comparing the two. I use the Touch to deliver a digital stream to my DAC otherwise.
I know the nodded version is terrific sounding, but I was looking for an excuse to sell my Transporter in favor of a Touch for the sake of improved sound.
