I got an RME adi-2 pro fs for headphones amp but I liked it so much so that I use it as a preamp, peq, AD in my 2ch setup. JDS, at 50% price of RME DAC probably offers 50% features (i.e., sans XLR, Decent display, multiple IO protocols etc.)

I'm on the fence..
 
Link please.
AFAIK, Element IV has no HW-DSP, and relies on the XMOS XU316 computing power to process library-based PEQ filters. I don’t think there is a guarantee they could implement a lot of new DSP things… especially if the corresponding libraries don’t exist at XMOS (no offense to the smart folks at JDSLab).

Definitely interested in your take.
 
The ADI-2 DAC costs $1300, so JDS is at 38% price. Pretty fair IMO.
JDS will cost 550$ soon, so it will 42% of that of the ADI. If I can find a used ADI DAC then I can bring that to 60%-70%.

So, I might wait.. because ADI is 100% superior in every aspect for my use case.

In Europe, with added on VAT and import costs Element will be more than 50% the price of RME ADI-2 DAC. And that is calculated at the current price, not the future 549$.

I think JDSLabs has a right approach here: managing complex DSP features on a device display can be done (see RME)…but quickly becomes very complex and may be the wrong approach in the end. At the same time, there is definitely a need to balance what can be done on the device itself vs. what is only available through the app—same debate as cars “information system”, touch screen vs. buttons, knobs, and dedicated sub-displays. The Element IV may be lacking a few useful on-board control, or a way to expand/overload the knob functions (short press, long press, double press, triple press, etc.) via settings in the app.

What John Seaber does not cover in his blog is what can and can’t be done with the XU316….
See the Neutron HiFi DAC V1 review thread https://www.audiosciencereview.com/forum/index.php?threads/neutron-hifi-dac-v1-review.56647/ for reference.
I know it’s ‘just’ a dongle… but the architecture is not that different, and Neutron is already fine-tuning the balance between adding more DSP features and how many of those can run concurrently vs. the available processing power of the embedded ARM processor.

The XU316 appears to be a fairly powerful (specialized) MCU, but it ain’t specialized DSP, that was my all point! :)

Very good insights..
Neutron HiFi™ DAC V1, is a good proposition and is within budget for many. Do you think that one can use output of Neutrino to a more powerful headphone amp?

No reason the output can't be reduced and run to another amp. But honestly if I were going to spend $180 on that why not go for a WIIM pro plus and go direct into an Atom2 Amp for the same money. WIIm gives you PEQ and a bunch more. Part of the attraction for me on the EL4 is it simplifies my set up.

Does Wiim pro have independent PEQs? Independent PEQ is a must for me...for 2 channel and headphones.

Yes I believe you can adjust left and right independently if that is what you are asking. Pro PLUS runs a AKM 4493 I believe also. There is a review on here and it measures well. I used it to my Atom2 with good results. Only reason I updated to a EL4 was to get rid of the volume potentiometer and wanted to declutter my set up. Also I just like the EL4 and wanted it. I am currently steaming the WiiM Pro Plus via optical into the EL4 from Qobuz. The WiiM has been great honestly. Easy to use and set up. I think you can even used different peq for each output.

Looks like the first batch is sold out, you can still order an Element 4, but it won't ship until after Christmas.
 
I hope guys don't mind asking in here as I am considering upgrading to the Element 4 if my current Element 2 is faulty,

I've noticed that when I run my fingers gently over the casing (including the knob) I get a tingling vibrating feeling on the tips of my fingers, a bit of googling suggests it's electrical mains leakage coming through the case?

My wireless AC Voltage probe picks up a strong signal when I place it a few inches away from the amp chassis, also I'm reading 18.7 volts coming of the AC adapter which seems ok, I've checked my mains is earthed (UK).

Anyone else experience this?

Email JDS they will get right back to you. You power transformer should be 15 or 16v. 18.7 is too high. Get up cheap tester at Home Depot and plug it into your wall outlet and make sure your grounds are okay.
 
As I said in the review, JDS has done this test.
Sure, but it's good to have it validated by a third party otherwise why would you measure and review any DAC that already had a full suite of measurements that the company had published themselves.

The mains is isolated via the transformer so it appears the 'tingling' from the finger rub comes from the DAC or whatever is connected to that DAC.
That may not be properly connected to safety ground.

When you want to find out connect the amp to mains only and nothing else connected to it.
When you feel nothing the amp and transformer is fine.
Connect the audio input and see if the issue occurs. When it does look for the issue in whatever you have connected to it.

This is occurring while nothing is connected to the EL Amp II other than power cable.

edit -

I emailed JDS Labs and they are sending me out a El Amp II+ to me in the UK to compare/test!, Damn these guys are good, their customer service is first rate, I'll definitely be chucking some more money at them even if it's buying another amp for someone as a Christmas stocking filler.

If you have another wall plug similar to the one from the EL (like if you have the EL DAC) I would swap it and see if the problem disappeared. That is great. They are a great company.
 
Looks like there is quite some leakage in the power supply in that case.
Is it also happening when other gear is connected to the input (that is connected to ground?

Are you using the power supply of the amp connected to some outlet that is not grounded ?

Outlet is grounded ,I have tested using a mains tester plug.

Interestingly the phenomenon doesn't occur when connected to my DAC, I'm guessing it's getting ground when the DAC is connected, is that safe for the DAC though?, My DAC costs like ten times the cost of the amp so rather air on the side of caution if it's unsafe.

Tested again without DAC connected, very apparent tingling touching amp.
