Take into consideration that A50III can reach 14+Vrms only from balanced output. I've decided to go with cheaper L30 II instead, because it was able to output 13Vrms from unbalanced, while unbalanced of A50III is limited to 7.4Vrms. Not that there are many headphones which won't be fine with...

Ye, reasonably we are looking mostly at some planars possibly being an issue, and realistically that is a niche within a niche. When it comes to popular dynamic headphones, if we would take 110dB SPL as target, then the main suspect would be HD599 50Ohm 106dB/V = ~1.6V, while something like...

Do you mean there is a way to force it? Like switching headphones when powered off or connecting one with adapter and then changing to another? Apple certainly dropped the ball here, not taking into consideration 2kOhm headphones.

I've just ran JM20 with L30 II on Windows, it is not the same dongle, but seemed fine aside the click/pop on start shenanigans which honestly it is better just not to think about. Ye 100% is right, some people will make it 98% out of a habit just to be sure there, which is not an issue as L30 II...

I will try to run some proper tests if I find some off time+bad weather :P in the following days, but I just gave JM20 a quick run to try it with an amp, since that what I bought it for and I sure am confused. JM20 > L30 II (TPA6120A2), Windows 11 23H2, desktop volume slider prompt - 100% loud...

My main concern is leaving it unattended. My flat gets up to 35 degrees in the summer, likely a bit more in the PC/audio corner, especially when the PC next to the adapter would be under load. I don't have a good thermometer, don't feel like standing with a mercury one by it, so only a cheapo...

It is a sharp, instantaneous click like a vinyl crack, scratch on CD, or a whip crack, shot. There is no ramp up/fade in effect or anything I would associate with muting. It is audible even with system sound effects, like the prompt when you move system volume slider. I will run some more tests...

Overly high output itself shouldn't be an issue with IEMs as according to staticV3 the JM20 will output only 1Vrms into impedance up to around 210Ohm, here is his post https://www.audiosciencereview.com/forum/index.php?threads/jcally-jm20-headphone-dongle-review.58749/page-12#post-2214533 Amirm...

Just a few hours prior I was just looking at my old (Socket 775) Scythe Ninja radiator lying around and thinking about how funny would a JM20 Max strapped to it look :P That said attaching even just a thin aluminium plate to that pad would likely improve it a lot, pads are ok at transfering...

I've got my JM20, and... there are clicks when launching a track. But! they are not universal! Android phone Mi Music (Xiaomi) - no clicks, nothing's cut! YouTube Music - no clicks, I don't think anything's cut but didn't test too much HiBy Music - clicks! HiBy Music in USB exclusive mode -...

On the official product page the spec says: "RCA Output Output level: 2Vrms" So which is it? Is the RCA output fixed 2Vrms or adjustable up to 3.3Vrms? Also any update if Amirm will be reviewing the K5?

It is an old trick used by many AliExpress sellers - they put the current year into the title or option box, so a customer who compares offers might start to worry there is a new version and he will be buying an old one elsewhere :P It is more common with handheld emulation consoles, and other...

Whatever you connect it to, L30 II does the job as long as you don't overdrive it. Meaning you won't fed it a signal way above 2Vrms. There is no rocket science beyond this really. It is actually fairly decent at connecting sources below 2Vrms, because its max output of 13Vrms is a bit of an...

As mentioned, apparently your headphones simply do not require an extra power the L30 II is providing. The amp remains transparent in this case. The output clarity of JM20 is 112dB SiNAD at 2Vrms, the output clarity of SU-1 is 116dB SiNAD at 2Vrms. I don't think you will find a person here who...

I think Topping needs to step up and further increase power in L30 III... as I'm ashamed to say I just 100%ed it... I mean, for my defense, it is not even 7mA! *at 2000Ohm :P*

It should run just as any 2Vrms dongle, I have CS-Pro CS43131, and now at night (completely quiet surrounding) on Windows for me that is 50-90% for music depending on a song and day, as I listen I would climb higher and unable to go down to 50%, and I can 100% and listen like that without...

Seems like can't edit posts after some time, so here is the updated list of JCAlly dongles which I was able to find, chips and power output are based on sellers so they might be inaccurate (particularly USB bridge/interface ones) JA series (solid/no cables), T = 90 angle JA3T - CX31993 JA10T -...

The limited testing we have available shows both USB and PCI-e devices displaying increased latency when compared to I2S onboard (no USB onboard like ALC4080 compared). Below the vid with some measurements by Chris from Battle(non)sense channel, Chris set standards in measurements of input lag...

You found me out, we actually put those in guitarist's chain to "process" people during rock concerts, so they would follow our commands :p

I still have no idea what my "Psycho Acoustic Processor" does, but it looks cool and became pricey over the years :p
