Binding Post fix for Hypex owners:
Below are several approaches for those DIY inclined who would like the peace of mind of having non-magnetic binding post tabs. While we verified the steel tabs on our binding posts caused an early rise in distortion in the Purifi builds, it is currently unknown (but probable) if a similar rise in distortion would be measurable in the Hypex amps.
Even if the distortion were to be measurable in a Hypex amp build, it is nearly a 100% certainty it is inaudible and does not affect real world usage.
***LEAVE THE AMP UNPLUGGED FROM ALL POWER FOR 30MINS PRIOR TO OPENING THE CASE***
Approach #1
1) Replace the tabs on the binding posts with these,
0.250" Brass Male Quick Connect
2) Cut off the existing female quick connect on the end of the internal speaker wiring and crimp on a new 0.250" female quick connect (plenty of options out there, just make sure they are non-magnetic)
Approach #2
1) Cut off the existing female quick connect on the end of the internal speaker wiring and crimp on an M4 Lug Ring Terminal,
like these
2) Secure the Lug Ring Terminal to the binding post directly (no need to use the tab anymore)
Approach #3
1) Replace the tabs on the binding posts with these,
0.205" Brass Male Quick Connect
*The existing wiring will work/connect to these tabs directly, no other modification needed
**This is the easiest approach, however these tabs are hard to find/not in stock in most places
Approach #4
1) Remove the female quick connects on the ends of the speaker wiring and solder the wire directly to the speaker binding post
