Hi,

Actually, not Quite.

Bent Audio has their own spec (also found in AVTAC and AudioZone), DIYHFS uses usually also Bent Audio Spec but with other leadouts.

MF Audio have a slightly different spec, which does sound somewhat different.

See:

for what 6moons has to say about the differences, sonically.

Ciao T
