I'll leave this here for the folks who like Unboxing Videos!!

Testing the line input (4.4mm) with the SE300 and the CHARYBDIS. Very good. The sound offered by this combination is simply splendid - if I were still listening with the PHOBOS now, I would have said that it is rather superb: a matter of nuances; the CHARYBDIS invite you to contemplate perfection; the PHOBOS, to embrace the performer.

Compared to the DIABLO OG, the tendency is the same: more sphericity, better image. Clearly. The SE300's amplification, while "sufficient," does not provide the same air. The SE300-DIABLO 2 pair is, in the portable arena, TOTL. For full-size headphone listening the SE300-like so many others at the same level-needs a bit more oomph. And the DIABLOs give it that without batting an eye.

As @Ferdinando1968 said yes it does, I would have to inquire about the Finale and post back when I get confirmation either way.

Cheers!!

Thanks. Yea little info on both diablo 2 and the finale on this. Especially since diablo 1 promised spdif mqa.

Still waiting for answer on the Finale, I didn't forget you..

Cheers!!

Does this device has a external power mode, like the xd05 pro, to prevent constant battery drain/charge while used in desktop mode?

The iDSD Finale does not have this feature, just got the news.

Folks, a brief statement on the measurement of the Diablo 2...

"We want to express our sincere appreciation to the community for your dedication to detail and commitment to quality.

Our current website renovation has unfortunately led to some inconsistencies, one being the omission of the word "maximum" in the power output specifications of some of the products, including the Diablo 2 (we did have that on the original Diablo page, this shows the inconsistence). We acknowledge this oversight and moving forward, we will ensure that our specification tables clearly state "Maximum power output," aligning with the original Diablo spec.

Your feedback has also prompted us to reevaluate our approach to presenting technical information, so we will list both the Maximum power output and the RMS value on the spec table of each product on our website to ensure that you can make informed decisions. We strive to continually improve and appreciate your dedication to holding us to high standards.

Further on the iDSD Diablo 2 design, it prioritizes the effective handling of real music signals while delivering optimal performance in terms of cost and size. We place a high priority on allocating resources to enhance the quality of music signals. However, this approach may not be fully apparent when solely considering RMS values.

Music features dynamic variations in loudness, rather than maintaining a constant volume. Typically, music has a 20dB crest factor, with peaks reaching ten times higher in volume. Our simulated measurement is achieved through simulating a 0dB signal at 1kHz, alternating with a one-on and nine-off pattern, allowing for a more accurate determination (from our experience) of the most relevant maximum power for music.

We will illustrate the difference between Maximum and RMS output using three examples below. It's important to emphasize that although Cases 1 and 3 may appear similar in terms of RMS values, Case 3 actually provides a significantly superior real music experience, akin to Case 2.



Again, we appreciate your feedback and will start to incorporate both Max (real music simulated), and RMS values into future specifications."

Hope this helps in the discussion as it is valuable to our community.

Cheers!!

I appreciate the due diligence you did. I tried the Susvara with the diablo 2 on ldac with a high dynamic range bassy track on 360 reality audio and the 40hz sub bass didnt clip the Susvara at all even when louder than proper listening levels. The sub bass didnt show like it's having a hard time. On regular pcm tracks, low gain is sufficient.

Kudos. Let's not mind the intentionally pernickety fear mongering claims scare people.

@iFi audio congrats and thank you for this much needed update.

We are certainly glad it is to your liking, I was very surprised at the BT performance as well, all in all, I was very pleased with the new updates myself.

Thanks for your support, appreciate it!

Cheers!!

They won’t answer that because the answer is “No”

Hmmm, the power section of the original Diablo worked that if external power was available (and sufficient in Voltage and current), it would pass this power to rest of the unit to run on the external power and would turn on charging of the battery, which would use any current available from the external power supply but not consumed by the Diablo's circuitry, to charge the battery.

Battery charging was "lipo standard" meaning the battery get's charged to where the charging current has dropped to 10% of the nominal charge current and then charging is turned off, until self discharge of the battery drops it below the "recharge threshold".

Additionally there should be a "desktop mode" that lowers the recharge threshold to ~ 3.8V if the unit is connected to power continuously after the first switch off and keeps it there until the unit is disconnected from external power.

I see no evidence that the charger hardware was changed for the V2, no comment on software as this was definitely changed.

Now I do not know what the "external power mode" on some other product is. On the one mentioned it seems you must switch manually between "use external power", "use battery" and "charge".

If external power was available, the original Diablo would charge the battery to full and then leave it alone. So there is no constant battery drain/charge, as long as external power is available and sufficient. It in effect automates the manual switch on the other product, so you don't have to remember to switch to charge when your battery is flat or accidentally drain the battery when you want to use external power because you forgot to switch over.

What @Thorsten Loesch has posted here to my knowledge is correct, once the battery is full it switches to external power, however, there is no physical switch for this.

I will double check this but again that was my understanding of how it works.

I also tried the original Diablo with the Tungsten... it was fine with that phone too.. and its a little harder to drive than the Susvara...

Thanks for sharing that the Diablo can drive the Tungsten. It wasn't so long ago people were hyping the requirement that you need a speaker amp to drive the Susvara. Now the same people are giving ifi a hard time with Diablo advertised specs. Even if the Susvara sputters, which it doesn't, omg its battery operated and a portable.

In the Diablo thread many people were torture testing it with the DCA Noire or Aeon 2 and claiming the Diablo will shut down. I tried the combo myself and omg, i wouldn't wear the headphone and just let the sound leak before it would shut down. Many people listen at unsafe levels and is asking manufacturers for more? This is why governing bodies took over and started crippling gain on cellphone and daps.

In the Diablo thread many people were torture testing it with the DCA Noire or Aeon 2 and claiming the Diablo will shut down.

People, myself included, were reporting what happened in those situations for technical interest, it wasn’t a “claim” it was a real world occurrence.

We went around in circles on this subject months ago, just because the shut down occurs at unsafe listening volume doesn’t mean it isn’t worth mentioning out of technical interest for those that were interested.

I still use my Diablo with the Aeon Noire and it does a fine job. That doesn’t mean it is the perfect amplifier for a low impedance and low sensitivity load and I imagine given that the 2 is essentially the same I suspect it would do the same thing, I won’t be buying one to find out.

The Tungsten may be very insensitive but it is also around 150 ohm so is in the impedance range that the Diablo excels at so the comparison of driving the 150 ohm Tungsten versus a 13 ohm DCA headphone isn’t even close to apples for apples.

End of the day it's a closed case and non issue as the the diablo delivered above fully functional performance for the claimed dca noire issue and even susvara. In fact it's a welcome safety issue to remind people to be watchful of their listening volume habits.

 

[BS5711]

Just because the current limit shutdown isn’t something that bothers you doesn’t mean it isn’t something that is interesting at a technical level to others even if it doesn’t affect real world usability.
