New Beyerdynamic T1 (2nd Generation)

[SRKRAM]

  My Mojo has no problem powering and driving my T1g2.
 
It can go very loud and to my ears has an abundance of headroom, control, panache and finesse.
 
Of course there will always be better and more expensive amps but Mojo's power seems more than adequate to me.

I'm pretty happy with a Mojo powering my T1 gen 2 as well, but I'm interested to hear what I'm missing - If anything.

Sure.
I've never been to a Cam Jam but I'm hoping to go to London in July and will take my T1 with me to try on different amps. Should be interesting.

I'm still looking for an amp or amp/dac and wondered if anybody has heard the Audeze Deckard with the T1 gen 2. I noticed that massdrop offered this combo a while ago, but there weren't many comments on it.
 
Another option I'm considering is the Beyerdynamic A20 and driving it with my Mojo. People seem to say this works well, but I wondered how it would compare to the Deckard.

I have tried using the Mojo directly with the T1 Gen 2 or feeding the Mojo's output to 2 different desktop amps and don't find the Mojo on itself lacking. If anything, the additional external amps make the sound just a tiny bit less transparent, and the sound signature changes just a bit - for better or for worse is entirely personal taste, but it wasn't as ground breakingly better in favor of the external amps as claimed by someone making a post earlier. The Mojo is definitely capable of driving the T1 Gen 2 to satisfying levels with room to spare.

Not to sound contradictory, but while the mojo's 35 mW @ 600 ohm @1khz may be adequate in some cases, it's important to remember that the T1 peaks at about 1400 ohms in electrical impedance in the 100 Hz region.  In general, you need headroom as far as voltage swing goes for this headphone.

There's no contradiction. You are both correct.
 
You are quoting machine measurements and GoSUV is relaying to us us what his ears tell him.
 
Myself, I trust my own ears and brain best-but it's always nice to have laboratory figures back me up.
 
Nevertheless, sometimes this isn't the case but I have never returned any cans I have really liked just because a machine (or for that matter a reviewer) tells me I shouldn't be liking the sound.

I also have an amp question. I'm using my T1.2 with iFi micro iDSD. It can provide: 5.5V/1,900 mW @ 16 Ohm in normal mode and 10.0V/4,000 mW @ 16 Ohm in turbo mode.
Normal mode is loud enough at about 12 using the volume knob. In turbo mode, 12 would be deafeningly loud.
But do you think it would be better to drive T1 at 10V instead of 5.5V ?

You should let your ears do the decision, not random people on the internet.

iDSD had some issues with channel imbalance at lower levels due to the volume pot from my understanding.  If turning it up to 10V means you can barely turn the volume pot before it gets too loud, I'd stick to the mode that you're currently using.

That is similar to what I'm finding using Explorer2 with and with out the A20 amp on T1.2.

95% of the time the Explorer2 has enough oomph. Once in a while I have it at 100% on recordings that are abnormally low. If I use the A20 in these cases it would be at like 75%. So the A20 isn't all that powerful an amp.

I have iDSD due today and mojo tomorrow to compare them all.

I like the iDSD with the T1.2.   Switching back and forth between normal and turbo modes changes the volume output significantly, but to my ears does not alter the sonic character all that much. Depending on the tunes being played, I will often use the bass-boost function with the T1.2 (it's pretty subtle but noticeable). I do not like the 3D effect with the T1.2 however. To me it sounds unnatural (although with some other headphones it is quite nice.)

That's a comparison I look forward to hearing about.

I don't think the A20 is a hugely powerful amplifier, but I believe that it can output higher voltage than things like the Mojo or Explorer (I recall calculating that it must be 8 or 9 v).
 
How do you have the volume set on the Explorer2 when driving the A20? Where you need to have the volume set on the A20 would be dependent on the output level of the Explorer2, not just the power or gain of the A20.
 
I'm really looking forward to hearing how the Explorer, A20 and ifi compare.

​The Explorer2 has a Fixed "Line Out" port.
 
I got the ifi iDSD BL Yesterday and so far I LOVE IT. I almost want to skip testing the Mojo and pack up the Explorer2 and A20 and be done.
 
But sometimes that can be "new toy" syndrome
 
I agree A20 is not that powerful, but plenty enough to drive the T1.2. A20 is about as powerful as the ifi iDSD is on Normal output mode. Explorer 2 is closer to Eco (but not quite that low). I love the Bass Boost on the iDSD. It's not too much at all.
 
I'm mostly concerned Mojo won't have the oomph I'm after. And it won't have the bass boost feature. I keep reading that word more "musical" though and I have to see what that's about for my own ears.

The ifi is really tempting. I'd rather have an all-in-one DAC/amp than separates, plus it is so powerful.
 
I've got a set of T5p gen 2's, and the Mojo definitely drives them well, but they're only 32 ohms and very efficient. The Mojo also seems to drive the T1s pretty well, but then again so does my phone - Up to a certain point.
 
Does turbo mode on the ifi make any difference to the sound? Bass in particular as that's where it would be needed, if anywhere. In regular mode the output voltage is about the same as the Mojo; about 5.5v rms. In turbo mode it's10v. I'm wondered if it would be worth getting an ifi iDSD micro as I already have a Mojo.
 
Many thanks,
 
Mark.
