The impedance is very unlikely to be the issue you are experiencing.
A lot of 32 Ohm headphones are very sensitive (like Grados) and will be noisier than a proper high impedance headphone on something like an OTL amp (the Bottlehead Crack for example).
An impedance mismatch between headphone and amp will lead to elevated distortion from the amp and boomy/loose bass response. Such an amp may also have a coupling capacitor properly sized for 100+ ohm headphones but not well sized for lower impedance headphones.
