Sorry, can't directly compare, but perhaps the DOGE would be the better partner with the K701s. If I remember right, the DOGE has a impedance selector switch - 60, 300 and 600 ohms. The K701s are around 60 ohms, so perfect combo.
The 332 doesn't work at its best with lower impedance cans like GRADOs and K701s. It can sound harsh and rather forced. Now, if you had SENNHEISER HD580s, 600s, 650s or BEYERs DT880s then I'd say GO for the 332. It's simply the BEST with these cans.
