The discovery thread!

On a different note, I ordered this adaptor.

If Penon or XINHS or someone else would make the same with two variable resistors in-between (0 to 50 Ohm, and 0 to 200-500 Ohm) for $15-20 more, it would be really great audiophile product to enjoy variations in multi-driver IEMs.

P. S. Edited "0" instead of "1" Ohm for the starting range of variable adaptors.

Hi Red, I don’t get it. This is a short cable that attach to IEM cable on one side and source on the other side? If one wants, say, 4.4 to 2.5, wouldn’t a ddHifi adapter more convenient than a long cable? Btw, that’s a long review article for a piece of utility, friend. I admire your enthusiasm for these small and affordable items.

Out of curiosity, what gear so you use the most often, knowing that you have lots of stuffs?

So did you order 4.4mm to 4.4mm? I mean I think someone could actually use the adapter aspect to go 2.5mm to 4.4mm and get the same audio effects but get the included adapter use? That’s the thing.....it’s in a way a cable and an adapter, in the outcome?

Just like you I hold my simple “silly” amplifiers/DACs as precious possessions. I don’t always use what sounds best (maybe what’s best with a particular IEM) as I’m matching sound signatures to gain understanding of IEM character normally. As maybe pointed out years ago the Sony WM1Z is both clear but bombastic lending it’s own ideas of sound. The WM1Z has a boosted and forward low-end plus an expanded (in soundstage) and throughly profound top end. The WM1A is more mid-centric and owns a faster bass, making the WM1Z’s bass slow by comparison. But I mostly use the WM1A, then the TA-ZH1ES to learn how its character works. And I will throw in at times the Shanling UA3, which strangely becomes the best playback once in a while. But I’m mainly trying to learn what characteristics are either pulled or pushed with different DAC/amps in relation to the IEM tested. I use MrWalkman’s firmware on both DAPs. The WM1Z will be brought out only if needed, like if I have a finicky IEM, where I need to add note weight or a style of warmth, the TA warmth is different as it doesn’t have to top end treble the WM1Z has.

To answer your question, absolutely your getting a tone slightly by the OS133. So, yes if you wanted a straight adapter then that may release less tone. Remember this effect is small and only noticed in certain situations, as I found at times it seemed to do very little, though if you had a brighter source and a bright cable it would add a noticeable tone to a relatively balanced warm/neutral IEM.

Simgot has released an interesting IEM which is tunable - not via traditional nozzles or switches - but by different cable plugs!

SIMGOT EN1000

$190 USD

DLC and beryllium plated composite DD

I suspect the "tunable plugs" function as impedance adapters? The FR just seems to change around the upper mids/treble region only (assuming store graph can be trusted).









https://www.aliexpress.com/i/3256804467634099.html

yes, got one on the way since some time.

cable plug ''tuning'' aspect is what make me contact them.

i was guessing something similar to impedance adapter.

it that but surely more complex too.

there you go for detailed explaination (email answer copy paste from Simgot, publish on Chifi Love FB group a week ago):

"We have observed that the frequency response curves of the 3 plugs tested by some people are almost the same before 8khz, and the curves start to differ after 8khz. According to the conventional test method, this test curve is no problem and is reasonable. We guess that this is a frequency response test instrument with an internal resistance close to 0 ohms or a very small internal resistance.

You should also be curious, it stands to reason that the curve change after 9 khz will have little change in the sense of hearing. But why is the difference in the sense of hearing of the three plugs more obvious than the difference in the curve?

This is because the internal resistance of the actual player device (front-end device) will not be 0 ohms. At least a certain resistance value exists. The interchangeable tuning plug is a very interesting new technical means. The traditional frequency response test method has not considered this kind of plug. In order to truly distinguish the curve differences of the three heads in the frequency response test session, simulate the real hearing changes under the three heads. We specially changed the test environment and test methods for EN1000 [including other headphone models with interchangeable tuning plugs], and deliberately added an additional resistance to simulate the internal resistance of the player device. We call it [distribution resistance]. This resistance does not exist on the circuit of the plug. Instead, it is connected in series with the audio terminal (3.5mm) of the plug, and then connected to the test instrument. Without this resistor, the test results are similar to yours. In the presence of this resistance, the amplitude of the variation difference of the three plugs will be more obvious, and the sensitivity will change. After overlapping the three curves at the 1khz position, you will find that after the curve is at 5khz, the trend begins to have a significant difference in decline. This can also explain why there are obvious differences in the sense of hearing under the three plugs.''

Graph, in the other hand, worry me a bit. but we will see once more of us try them i guess!

2.5 to 2.5 for my purposes.
(I am not with "bigger/better" for 4.4)
I had to custom order before.

The R3 Pro Saber has such good synergy with dynamic drivers. I don't have my Blon 03 anymore (only the newer Blon) but I'd probably recommend going balanced with it on the Saber which should boost that upper mid/lower treble just enough to even out the mid treble energy. Sure the Saber has a bit of bass warmth too but going balanced keeps it very tight and controlled.

Edit: Or wait for the new one to drop.

No mention of which DAC chip they use.

Looks good; specs are very solid.
Ordered for my dongle stable to compare with Apple (super value, no matter how audiophiles try not to admit it).

As for the chip - it is secondary to overall engineering.
Case in point - ESS-based Shanling UA2 - there is a noise out of ESS (!!!), so god awful specs (which they do not publish, understandably), while some may like heavy distrortion of the "house signature". Coupled with reading the UA5 thread, with all the problems reported and not addressed, and the company ideas on "software readiness" - Shanling is totally banned out of my audiophile universe forever.

Yep agree the DAC chip is secondary to implementation/tuning.

More important would probably be the dongle's output impedance (based on the audiophile rule of 8ths), cause some dongles with high OI may not pair well with low impedance IEMs.

Are you me? I ordered exactly for that same reason

Same, there is no scale on the graph, but the gain from what I estimate to be1khz to 4khz does look a bit scarey

 

[morndewey]

If one uses words arbitrary - then words lose their meaning... I will end the conversation here not to chop your arms and other body parts...

Not lose meaning, but accrue new, non-standard ones via popular usage. Language would be a kind of brittle straight jacket without this process.
Should one insist that “organic” only be used to describe relevant chemical compounds; “dynamic” only for quantitative changes in volume and not for an energetic, colorful, compelling expression?

Look forward to your review! Let us know how it is!

This statement makes me think about the power reviewers wield over small manufacturers. I imagine one bad review can easily sink an obscure product

Also works the other way round. One good review can create a hype train.
Then there are those that don't get the big review and go under the radar.

Just collab with big reviewers. Small reviewers wouldn’t dare to say they suck in fear of down voting
