Equipment Report like mastertapes (or dubs of same). The chief problem with the Invictus was never son- ic; it was ergonomic. Almost everyone with the means to purchase it loved the way it sounded, but was stopped short by the amount of space required to house it. To help resolve this issue, roughly two years ago Frohnhoefer and his design team began planning for a new version of Invictus. In addition to downsizing the beast, the Acoustic Signature team had fresh design ideas about both ’table and ’arm. After all, the original was cre- ated five years ago, and a lot has changed technologically Acoustic Signature Invictus Jr. in the past five years.
