Sorry, I am a little confused about what you are suggesting…. Just in case, and forgive me if I am stating the obvious, but let me stress, do not, under any circumstances take a cable that is terminated as Single Ended (3.5mm or quarter inch) and use that in a 4.4mm jack. You can probably jury rig a series of adapters to make it fit, but you will be creating shorts and damage or destroy your amp.
I meant 4.4mm to 3.5mm adapter.

I wish the W2 had a line out option. Want to try that amazing DAC with some proper amping power. Such a shame...

Is this something they can ever update using firmware or does it require physical circuits?

Sent an email to L&P asking about this. Will see what they say.

Try a balanced 4.4 cable it increase the power output of the W2. I’m using low gain the highest volume is under 70% and normally have it set at 60% with the moondrop variations and a balanced cable.

I think they are talking about wanting a line output at 1V bypassing the amp circuitry

Exactly. I want to plug the W2 into a proper amp and use it purely as a DAC.

W2 has all the power most iems need but it can't really get the best out of full size cans, more power is needed.

Been enjoying the W2 connected to an iPad Pro today after a week of just using my DAPs. Wow! I used “Fast” filter and “Tone 01” with Sony IER-Z1R and I liked it better than my standard settings (Fast/Tone02), maybe because I was playing mostly recent POP/Rock/EDM.

@bluestorm1992 this made me wonder about the FLT and Tone settings L&P use when designing their IEM EQ settings. Since you mentioned my favorite Sony IER-Z1R may be getting an EQ setting in the next firmware, I was curious if that setting will sound best with a certain FLT/Tone combination.

Cheers

Well I connected my W2 SE output to my Xduoo05 Plus Aux input after another head-fier confirmed it was safe.

It works wonders! Very pleased. The W2 keeps impressing. Another killer use for it.

I have a Hugo2 and the sound I am getting from the W2 with my D8k Pros is not on same level but it's not lagging far behind behind. Hugo2 is more resolving and has more bass control/treble/separation but the W2 experience is smooth and super musical. Perfect for a more laid back listening experience.

I really cant fault the W2 myself.

It drives my Aonic 5's, IE300's, 7Hz Timeless perfectly.

The SE846's sounded good to some extent. The background is completely black which is a plus, however, the overall synergy is off... They sound a bit too lifeless with the W2. So much so I sold the SE846's... In hindsight I should have changed amp 😂

I was watching a movie last night with the W2 and EP05 earbuds. It iss called Sea Fever.
I was impressed with the details, clarity and very open soundstage this combo provides.
The bass was very realistic and it sounded more like a full size headphone then an earbud.
I really recommend them if you can find a genuine pair.

Line-out technically required a physical circuit design change, not something a firmware can "add" magically. What L&P can add is a fixed voltage output mode, but it is not a real LO and mostly done for convenience / placebo purpose, such as what Chord has done on Mojo.

However, W2 headphones-out is so clean that it has better SNR than what the DAC chip is rated for, and thus adding a line-out, even if possible technically, will not actually improve the SQ, making it mostly a moot point. So basically you just need to set your W2 to a decently loud volume that will not clip your amp, you are all good.

Just an addon:

With Android smartphone volume set to 100%, W2 should be able to output around 0.74V Max (*no load) on single-ended, and almost double that to 1.46V on balanced-out. For those who wants ~1V output on balanced-out, you can set W2 volume to 96. However, do be careful that your amp will need to support balanced-input if you want to double amp W2's balanced-out. I don't have an iPhone to test, but I doubt W2 will output more due to iOS current limiting.

With PC's volume set to 100%, W2 should be able to output around 1.99V Max on single-ended, and almost double that to 3.95V on balanced-out. For those who wants ~1V output on single-ended, set W2's volume to 92. For those who want ~1V on balanced-out, set W2 volume to 84.
