I received my DV today.. Simply amazing.... Currently switching between my Grado SR80e's and my newly acquired HifiMan HE350's.. Too early to do real comparison, but the HE350s sound wonderful! :) Time to order some tubes and do some rolling...

I'm surprised those low ohm headphones drove well off that amp, being OTL and all.

Actually, me too! But they do sound very nice to me... :)

it's not like OTL amps can't drive low impedance headphones at all. It is just not ideal due to the typically high output impedance of OTL amps (see 1/8 impedance rule). The higher the amp's output impedance, the greater the voltage drop with low impedance headphones, making it a struggle for some of these powerful OTL amps to drive low impedance headphones sufficiently despite easily driving high impedance headphones.

Yeah, that's why I said I was surprise those low ohm headphones he had actually drove well off of it. Especially the HE-350's being like what 19 ohms? The Grado at 32ohms, I guess should be fine since the Darkvoice is rated at 32-600.

Did you do any mods to the capacitors to get the HE-350's to sound correct?

No. Nothing yet... But probably will at a later date.
