I used to think I didn’t need a sub. Then I got one. Now I have 2. Properly integrated subs are a game changing upgrade.

Agree, the remastered zeppelin sounds amazing, just a lowered level so you have to turn it up more. I use Since I’ve Been Loving You on III as a demo track. Also the remastered Beatles is incredible, Come Together another great reference track.

Modern recordings can use much lower frequency levels that older recordings simply don’t have. Too much bass on a record would make the stylus jump out of the groove.
