Should get mine in less than a week, will share my impression then.

Moondrop released EVO, priced around US$70 or so.

If you recognized these, you are certified old fart in the forum.

Digital filter is like seasoning, everyone has his/her own preference. You can only find what 'taste' best for you by trying them all out by yourself.

You are correct that it is a hardware limitation. FC6 uses NJU72315 volume control chip and it offers 0 to -62dB control via 2dB steps, meaning it is 31 steps total.

Perhaps I should be more clear - I am not saying it isn't possible to up-convert the power rail above +5V / -5V, but the higher it goes, the more difficult it will be. to keep the circuit in reasonable size/complexity to maintain a clean power. The way FiiO partially solves this issue is by...

Voltage swing determine how loud the headphone can get. However, don't forget KA17, even when powered by external Type C source, still operates on a 5V USB power rail. Generally the quickest way is to flip the USB power rail into +5V / -5V rail which that amp section can work to generate a...

I'll see what I can do.

There are several common ways to implement volume control in USB audio devices. The first is to do it on the source devices' audio core by reducing the digital bit-depth of the raw PCM audio data (again, every bit gives you 6dB of range). This is generally considered the worst of the choices...

BTE-8 is here. Really a no-brainer consider the cost.

The nature of being a 1-bit DAC means software volume control will never work as one single bit of data only gives you a range of 6dB to adjusts software volume before you lose the whole bit of data. It is both non practical and detrimental to SQ if software volume is enabled, thus analog...

Go Blu has the classic iFi tuning which has more of an analog quality to its sound and by all means a great BT adapter, but I am not that inclined to recommend iFi these days because they are often more expensive than the competition on where I think they should be and built quality isn't as...

FiiO KA17 with a small power bank in desktop mode is great with anything demanding power. iBasso DC-Elite is excellent as well, easily rivalling most portable DAC/amp.

TimeEar BTE-8 QCC5125 + Dual CS43131 + 3.5mm SE + 4.4mm BL + LDAC + LHDC Priced at only $50, kinda a steal if actual performance meets its spec.

The first question that arises in my mind is, given the similarity in hardware between Kensei vs. regular Go / GOld Bar, isn't it all but possible to just implement K2HD via a firmware update retroactively to the original variance? The 2nd question, or perhaps more of a personal opinion, is that...

If your are referring to GOld Bar, it does have 4 of those electrolytic caps instead of just 1 in regular GO bar or 3 in this new GB Kensei. Pretty sure those make more difference in sound than copper vs aluminum housing. In another note, I'll more interested if there is a way to disable K2HD.

Because opamp are part of the THX AAA 78+ architecture. THX AAA is a kind of headphone amplification circuit design / topology, it is not a single chip. It doesn't matter which exact components it used, as long as the whole topology follows the design, it is still THX AAA.

For all seriousness, an entry level Intel based mini PC with Windows already installed will only cost half of KA17. All you need is to have a keyboard, a mouse, and some kind of screen (TV with HDMI input will do) to have a working PC that you can update your KA17, or any simple application you...

You can find 22 ohm (P) and 100 ohm (S) cable at Lunashops / AliExpress under the brand EachDIY. B cable probably need to be custom ordered as there just isn't enough ER4B user around to warrant keeping stock for seller / builder - that also means it won't be particularly cheap or fast to get...

ER4B is the first to discontinue in the original ER4 series, so the chances that you can find one are much slimmer than ER4P/S. My advice to you is to find a pair of ER4P or S, then get a properly spec-ed aftermarket ER4B cable (drivers are all the same for three models). Alternatively, you...

I have the BT20 and BT20s Pro, but didn't pick up any newer models because there simply isn't enough difference for my interest. The thing about Qualcomm QCC chips is that almost all of them, regardless of higher or lower end models, share identical internal DAC section so SQ is inherently...

Just found this on Taobao: https://m.tb.cn/h.5E66HGv?tk=hIsfWNhiWPM QCC3071 / QCC3081 based with LDAC support, unfortunately no external DAC/amp chip. It is however cheap enough to warrant a look at ($40~57). I'll probably pick one up just for the fun of it.

If you are limited to TWS only， the real choices are between 1) iFi Audio Go Pod - super expensive for what it does but does delivery the best SQ of any TWS out there . 2) FiiO UTWS5 - the best balance between price vs SQ, and 3) everything else, usually decent but also unimpressive compared to...

For about US$90, MoonDrop Little White seems like a good option.
