This "feature" really bugs me, because the audio of every track played from my Squeezebox Touch is clipped at the opening moment!

I would love to know what a before and after set of measurements would look like from these mods. Sure, people can have all kinds of expectations that this or that cap, resistor, fuse, power supply will lead to sonic improvement... That's fine if they have fun with it and it sounds good to them.

Perhaps it is a pain to setup or has technical limitation as I’m no expert on these matters. RDhttps://www.blogger.com/profile/06928915370022771879noreply@blogger.com
