I can't find any measurement above 600Ohm. But best guess is @1200Ohm O2 can deliver up to 40 mW (7 * 7 / 1200) which is around 118dB. But most probably it's around 115 dB at worse which is still very loud.

headwhacker,

 

May I ask how do you find the T1 powered solely by DX90? Is it loud enough? Would you describe the sonic differences in comparison to any other dedicated amp? Thanks.

For pop/rock music have I have it plays loud enough and I can't max the volume in DX90. Except for classical which have a lot of soft passages I can max out the volume. I only have the Centrance Hifi-M8 (which can deliver up to 1 Watt) I have not done and critical comparison yet and my initial impressions may change. So far what I like straight from DX90 is that imaging, instrument placement and separation and depth is much better than M8. DX90 has a very noticeable quiet background compared to M8.

Seems like the T1 being a semi-open headphone could be used as a solid semi-portable alternative. I might get the DX90 myself in the future, though the original plan is to get an IEM to pair with it.

T1 leaks a lot. I would not use it as a portable.

I'm not going to use it as a portable, but a semi-portable. For example, if I'm going out of town, bringing big amp and dac to power the headphone is not practical. If a small DAP can power either of my cans to a sufficient level of volume and SQ, it would make my life much easier and so far the HD800 seems to be pickier than the T1.

I wouldn't mind walking around the house with my T1 and DX90 or walking in the park. But definitely not around town. People within a couple of meters around you will surely hear the sound leaking and may bother a few of them. If I leave it in my room while playing, leave the door open and walk towards the kitchen 8 to 10 meters away I can hear the sound leaking out.

what an amp 'can' deliver tells us nothing about the distortion of the signal at that power output.  more important is what it can deliver clean and on demand at any time regardless of what came right before it.

They're not the same, because I have all three headphones, and they all have slightly different pads. DT880 pads are not as deep and have a big opening/thin earpad, DT990's are deeper and have a smaller inner circle.  None of them are exactly the same like the T1 pads, and the material is also different, both foam thickness and stiffness, as well as the velour, which is more fine on the on T1's, and more "hairy" on the 880's and 990's. And yea, grey looks bad on the T1's lol.

Probably wont find any major sonic differences, apart from different levels of loudness. What I find about the T1's is that they sound surpsingly good out of pretty much anything decent. I mean, I can connect them to an iPhone 4S (still the best sounding smartphone out there) directly, which can run them to low-medium volume levels, and if I volume match the iphone with the Musical Fidelity M1HPA headphone amp, kill me, but I can't hear a difference between the two. Granted, it's not perfect A-B testing, since it takes about 10 seconds to unplug the T1's from the iPhone, plug it into the M1, and plug a 3.5 to RCA cable into the iPhone which then feeds the M1, but I really don't hear a difference. I can focus on some really specific things in sound, and both reproduce them equal. Especially the bass, it loses or gains nothing in terms of tightness, impact, texture or extension. Playing 25 Hz tones....identical on both.  There might be some difference obvious at higher volume levels, but at  low-medium (basically relaxing listening level) they sound as close as it gets and I have no reason to believe I'd be able to differentiate two setups in a blind test.

 

This is granted that both sources measure above what is audible by human ear in terms of distortion and noise levels, as well as perfectly flat in the frequency response, which is true in this case.

I ordered replacement pads for my T1's from a Beyer dealer and the part was labeled EDT990VB. They do seem to be the same depth and identical foam and velour as the original. I still have the original pads around and I compared them I can't see any difference.

+1

 

I just swapped pads and I can't see any difference between my stock T1 pads and my replacement EDT990VB (except that the EDT990VB's come with a disc insert that you can install (or not).

You have me worried...I have the M8 on order and never thought an all in one device like the DX90 would perform better than a dedicated DAC/Amp...I have yet to find a less than stellar review of the M8...and many say it rivals desktop amps.

At the same power level, I like the SQ on DX90 than M8 specially on iems. As a portable rig, M8 is starting to show it's age. With the latest DAPs coming out from different manufacturers, the days of carrying a stack for portable rig is almost gone. But M8 is still a very good/compact desktop replacement with the amount of power it can deliver and output/input options. It's still a very good value device.

 

But for T1, DX90 alone is keeping my M8 seldom used at the moment.

Giving me more incentive to get the DX90..
