driving hd580s with Porta Corda MkIII-USB or headphonia

[rhy]

can either of these drive hd580s with ease? or any other portable amp/dac combos that i'm not thinking of? total bithead is out as i've just recently acquired one and can't seem to get the volume i want without clipping. getting some advice on other options before i make another splurge.

looking for people with experience with the tbh/hd580 combo as i've seen people here say you shouldn't have a problem using the two together. guess i just need more volume than your usual head-fier.

Porta Corda II had no problems with hd600 or hd650, I don't see why the III should have any problems with hd580 =]

do they make II in USB as well? i failed to mention that this is strictly for comp as source.

III is the updated version. II was an older model that I have. III USB will do just fine for you.

in the several months i've been checking the amp sale forum i don't think i've ever come across the III-USB. how much is retail?

Todd the Vinyl Junkie also sells Corda amps. The newest Porta Corda version has an internal switch to adjust gain. Maximum gain is 17dB and that's a lot, so you shouldn't have problems to drive virtually any phone even from a low level source.

I use my PC MkIII-USB often with my PC...sorry, I'll never sell mine.

It drives my HD 650 very well. I leave mine at high gain and use 13 volts to power it. It can use up to 28 volts I believe. Power is very good with fresh 9 volt too.

i must mention that i had plans to power this solely off USB. for all i know the TBH could drive the 580s just to my liking via batteries, but i don't care much to go that route to even find out. can the III-USB run both it's amp/dac off USB or is it battery required?

also about how many hours do you guys get out of it?

The Porta Corda MkIII-USB can be powered (amp & DAC) from the USB power alone. Using USB power it still has very good power from my experience. Just today I got permission from Dr. Meier to use the 30 volt setting on my AC adapter.

I notice a nice improvement with this higher 13.5 & 30 volt power over the USB or 9 volt power. This improvement is only realized when driving hard power hungry cans such as my Darth Beyers which require solid power to reach their limits , bass wise. OH YES!

I have never tested battery life with either alkaline or NiMH. Battery life seemed to be decent though.

I got about 20-30 hours out of it easily on one battery.

I was going to guess 40 hours max. At one time I was using it in a portable situaution but that was too long ago to be precise.
