I have Mullard 5654, Western Electric 403B, Telefunken CV 4010, Tung-Sol JTL 5654/6AK5W. My preferred (for now) is a Telefunken CV 4010.

The 332 has a pretty cheap pot. If the FIGARO is anything to go by, it's probably a carbon type - 100k perhaps. Whipping that out would be a worth while upgrade.
In my opinion, the HD650s have to be driven hard. At lower volumes they can sound a bit soft and bland.
Best-case scenario: The Herbies will fix the occasional whine (and possibly improve sound). Keep the foil. Remove the cheater plugs. Tubes are clean. Bliss.
Worst-case scenario: Herbies go back. Keep the foil. Keep cheaters. Clean tubes. Occasionally have to tap a Svet to eliminate whine. 99% near bliss.
