All the XM? line of amplifiers only output 75mW into 120Ω from the info on the site, my FiiO E09K outputs 150mW into 300Ω and I usually have the volume around 11 o'clock.
So personally I think the XM? line might be a little lacking in output to drive the 250's and possibly other higher Ohm headphones.
 
If I was looking for a portable in the price range of the XM5 I'd check out one of these C&C XO2's, lots of power and a great battery life from the specs. If it is anything like the C&C BH, people are getting over 80 hours battery life.
 
 
Others will chime in with their suggestions as well.

Also..

I have been interested in the xm6 for a while and the beyers may just be an excuse :0).  

 

I cannot for the life of me figure out the 1/8th rule and there is no standard way amp makers show amp their output so I find it hard to compare.. I assume (based on size and the fact the XM6 has a battery and is not powered from usb) that it puts out more power than the Dragonfly.  And I hope (reason for post) it is powerful enough to drive the DT880 250 and maybe even higher ohm phones i select in the future.

 

Thanks for your interest!

 

Ah yes, the 1/8 rule! It is just a rule of thumb: headphone amp output impedance should be 1/8 the impedance of the headphone. As you point out, a lot of headphone amp manufacturers DO NOT specify their output impedance. One thing going for the 250 Ohm DT880 is that just about any headphone amp (especially solid state amps) have an output impedance of 250/8 = 31.25 Ohms or less.

Bass is excellent.. smooth, quite linear with excellent sub bass presence.  Mids are clear, uncolored, and organic.  In terms of positioning, I was worried the mids might be recessed.  Thankfully, that isn't the case.. but they're not forward, either.  Treble is clean, extended and again, neutral for the most part.  It can get a bit "spot lit," but that seems to e a consequence of the recording quality of some tracks I've played than the phones themselves.  One thing I do notice about the presentation is that it can feel a bit distant a times.. as if I'm sitting/standing closer to the back of the auditorium or venue than near the stage.  I'm not sure I've heard a phone that positions me this far back.  It isn't a particular weakness.. just something I have to adjust to.

Thats going to be my set up! Sweet, I'm glad it works. I just bought a Crack with Speedball.

I own an XM6 and it actually outputs a bit more power than that. The 75 mW figure is only with the copper busbars in place of the output buffers. I'm not sure what load the 1 W figure is specified for, but the XM6 has no issues with my DT 990 Pro and HD 580. I was able to get good  volume on a LCD-2 and DT 880 600 ohm as well, but you may want a bit more power for those headphones.  

 

Full quote from the XM6 page below:

 

What is the power output of the XM6?

The XM6, when equipped with BUF634 output buffers, is capable of outputting on the order of 1 full watt per channel. When using copper busbars in place of output buffers, the XM6 can output a maximum of 75mW (milliwatts) per channel, when operating into an ideal load of 120 ohms. Since most headphones usually have a sensitivity somewhere around 100dB per 

1 milliwatt, the XM6 has plenty of power to spare.

I stand corrected, I should have read a little further down the page. redface.gif

I've read a lot of reviews and posts on Head-fi that helped me choosing several headphones (Grado, Senn and Beyer) over the years and would like to thank all those who have chimed in on this forum.

 

I just received my DT 880's (600 ohm version) yesterday and am in love! The sound far exceeds my expectations. Apart from my small collection, I've also tried out many mid and high end cans in shops, and these are spectacular in every dimension.

 

I'm currently running these with integrated Conexant HD audio (CX20672 I believe) for now. Its DAC/Amp combo provides more than enough power (2WRMS per channel) and surprisingly very nice sound resolution to my untrained ears. The integrated Dolby console helps a lot with the latter -- as a software developer, I appreciate the power of algorithms! Looking forward to moving up to dedicated external components at some point :)

Call me crazy but I bought the 880 pro's for $300 shipped in India still about $200 cheaper than the ones available here in India.

I wanted a brighter set for rock so I decided to sell my ma900's and get the 880's , lucky for me headphones have a good resell value in India

I now am close to complete the classic trio - 650's and now the 880's :D - will never buy the 701's , probably :D

 

FYI - The main reason I sold my 900's was because they were dark as my 650's so ..........

Cant wait for my first Beyer's  (Est delivery time by end of Sept - ordered via Amazon Global) :D

Well, those are sexy.

What are the effects on sound?

From what I can tell, there is more bass. And I say this with authority, a lot of it. It sounds so much better. So much. Even MCA compared these to the D7000 and LCD-2. You know that means something!

 

Also, don't take the above as fact, I will listen more thoroughly through the next week or 2 and give my final impressions.

They certainly are pretty. That wood positively glows. The only thing that detracts from the aesthetics (of course IMO) is the size of those holes. I think they'd look nicer with larger grills. I'm sure this has an effect on the sound, however, and that this particular design produces the desired acoustic characteristics.

 

Or maybe they just liked it. That's always possible.

I don't know the method to Martin's madness, but whatever he did, it sounds fantastic.

They look very much like the Grado RS1's.

Yup. Don't know why but they just reminded me of the RS1's tongue.gif
