I have had ample opportunity to thoroughly lsiten to all the Pink Immersion Box Sets. These are worth it for the Live Discs themselves. Guthrie outdid himself on the mixes. I do not regret getting them and am glad I did.

Just recently I purchased the Pink Floyd Discovery Box Set and The Beatles Stereo Box Sets.

Floyd: It is great to FINALLY see most of the tape hiss that plagued all albums from A Saucerful of Secrets through Atom Heart Mother all but vanished. Animals needed a good rework, as did A Momentary Lapse of Reason. Guthrie again, did great work with even the volume levels. The volume level is constant from Piper to The Division Bell. Which I thought was a nice touch.

The Beatles: The first four albums finally in Stereo, sound absolutely astounding! [Please, Please Me, With the Beatles, Beatles for Sale and A Hard Day's Night]. The other mixes are terrific as well. Revolver just sounds crisper, than the older disc's I had. Abbey Road, which is my 10 year old son's favorite album by them, sounds fantastic and has finally received the "pop" it lacked in the older disc. The White Album is devoid of a few key tape hiss issues.

I regret getting none of the above, they are worth the money.
