The difference would be frequency response.Hmmm, what would be the difference of listening at a 80dB SPL on the 250Ω DT990 vs 80dB SPL on the 600Ω DT 880?
The vast majority of external DACs will output 2Vrms or higher.Which external DACs do you think that could output 2Vrms or higher? is higher better?
Currently using the Xduoo MT-602 to drive my 250-Ohm Beyerdynamic T90 headphones.Interesting, I've read quite a lot of reviews, that would imply that Tubes aren't good with the DTs as amplifiers.
I've also read somewhere that the xDuoo MT-602 is good but didn't make my list since I don't see a spec sheet saying a stated metric for mW @300 or @600 ohms. Also, it says it;s a hybrid tube plus Solid State?
- is this the DT880 250Ω being compared to a DT990 250Ω?
DT880, 600Ω: 8V = 114dB SPL peak = 0.1W
- what would be the minimal output voltage and higher gain metric for the 600ohm DT880 to reach its maximum rated SPL/mw?
- I'm quite interested on the Schiit Magni Heresy, besides their website, are there other listing that could potentially ship them to Asia? The Amazon listing apparently does not.
- Would you have a suggestion of which 2in1 at maximum 250USD that could potentially power the 600Ω DT880's maximum rated SPL/mW rating?
- Would you have other AMP suggestions?
Ohmygod you are very helpful, one last question and i'd remove myself from this forum,Old DT880 vs DT990.
The current DT880's do not differ that much from DT990 any more.
Don't stare blind on the reports that the 600Ω is the one you need and sounds better. The differences are small. DT880-250 (old) vs DT880-600 (current)
DT880, 600Ω: 8V = 114dB SPL peak = 0.1W
DT990, 250Ω: 5V = 115dB SPL peak (122dB in the bass) = 0.1W
All the ones I did not mark 'avoid'.
If you want to reach uncomfortable loud levels basically all outputs that are specified above 150mW in 300Ω will do fine.
You'll need at least 15dB gain (with 2V output DAC) or 18dB gain for when driving from a dongle or phone.
You'll probably never reach those levels, the bass distorts audible at these levels.
When you only want to reach comfortable loud levels 40mW in 300Ω is high enough and gain can be 6dB lower.
A piece of toilet paper between the driver and the foam disc can lower the treble peaks (when bothered by it, some people love it)
Does this include those I listed under the DT990 lineup?All the ones I did not mark 'avoid'.
Hi man @solderdude , I'm looking right now at the Topping L30 II and DX3 Pro plus.It depends on how loud you want to go and whether or not you plan to add subbass using digital EQ.
If the latter you may want to look for amps with higher gain and at least 300mW rated in 300Ω
With their spec sheets above, does this mean that the L30II could power the 600ohm DT880 better than of the DX3 Pro plus?
Hi man, so here I am still left without a solid choice for an Amp for the 600 ohm DT880.DX3 Pro+ = 7.6V = 96mW in 600Ω (sufficient to play loud without EQ)
L30-II = 13V = 280mW in 600Ω so can play 4.6dB louder than the DX3Pro. 10dB is about twice as loud so 4.6dB is louder but not twice as loud and sufficient to play loud with EQ.
Noise level is not important for these insensitive headphones nor is the difference in distortion.
Guild lines are that for the best damping control of a 600-Ohm headphone, is a headphone amplifier with an output impedance of 60-Ohms or less.Hi man, so here I am still left without a solid choice for an Amp for the 600 ohm DT880.
I saw this video on youtube of a guide explaining that i don't need more than 100mW output rating @600Ω BUT more on impedance matching where the 600Ω DT880 requires 100Ω of "output impedance"
So I searched and found this Samsom S-Amp that has a rating of 100Ω output impedance but doesn't say anything about xx mW @600Ω rating(was hoping that it would at least output 100mW). Pretty weird because this hardware is around 30usd only on ebay but modern amps costs at least twice.

Does this mean that the 30usd Samsom S-Amp could actually drive the 600Ω DT880s?There is no 'impedance matching' for headphones.
Some of the older headphones were specified to be driven from a 120Ω source though
Safe to say a 600Ω headphone can be driven from a 100Ω source.
The headphone amps I designed for Garage 1217 have a select-able output resistance for that reason. 0.2Ω, 33Ω and 120Ω.
Below the difference of the DT880-600 driven from 0.2Ω and 120Ω
As you can see it makes no difference.
If anything, when you don't need Harman bass, I'd deal with 'mount Beyer'.
Thanks once again. When you say 4.7V in 600ohm, does this equal to 4,700mW?Probably capable of delivering around 4V in 300ohm headphones and 4.7V in 600ohm and 1.2V in 32ohm.

Also, someone claimed that 100Ω output impedance amps help produce better Bass response on the 600Ω DT880 that the modern amps fail to do so, but are doing better at mids. would this be true?
