I'm not sure if this is the proper place to start this thread, but I've got the upgrade bug thanks to my new m60s. So first, has anyone picked up a music hall cd25. If so some feedback...please.
And finally what is the actual 'real' audible difference (if any!) in these so called upgrade mods on the cd25 and other units? The mod details for the cd 25 are available at

Thanks for the help folks!
