The DFI is much better that the DF-01 Orb. Just treated a dozen albums that the Orb did not flatten. All perfectly flattened with one treatment on the AFI. I’ve never seen a flatter record!
Yes, it’s 3X the price, but it’s 10X better.
Also, the Relax program is very interesting. The benefits are backed by material science. I don’t have two copies of the same album to do back to back testing, but those who did try this all said it makes a noticeable difference.
Main Differences vs Orb:
More precise temperature control.
Two heating cycles: first goes to 40C, second goes to 60C (adjustable)
Controlled cooling
Orb goes to 65C then turns off. 65C may damage some records. Not adjustable.
Orb doesn’t have the “Relax” program.
no annoying “only treats records with an edge guard” requirement.
From a German review:
This careful, absolutely clean cooling with identical conditions above and below the LP is also the biggest difference to the ORB-DF 1i record iron.
This heats the LPs to 65 degrees and then turns off. However , the sophisticated heating technology of the AFi flat.2 has unfortunately at a price.
