Speaking of ES100, it has very good audio performance. As pointed out in a comparison with BTR3 done by ES (https://drive.google.com/file/d/16RNUu48icvjbvjCnMzAv0GoU6dI9hotT/view), CSR based solutions may suffer from a design flaw (Tone noise around 18KHz and 20KHz). I don't have the measuring equipment as well as have zero knowledge on measuring these parameters. So I wonder if anyone knows if @FiiO has addressed such design flaw?ES100 is great. Get it if you need a BT amp now.

The tone noise are almost 100dB below the test signal, you are not likely going to pick it up with normal human ears.
Thanks!The tone noise are almost 100dB below the test signal, you are not likely going to pick it up with normal human ears.
A follow up question just out of curiosity: Does this kind of noise pertain to the software/DSP logic or the hardware design?

Thanks!

Consider that Eadsone makes it clears the noise only affects 44.1KHz measurements (48KHz measurements look clean), I'll say it is probably an clocking related issue related to how the inner clock works in CSR chipset. In that case, this will be more of a hardware issue.
You enlightened me a lot.

Is that also the reason why FiiO stuffed dual crystal oscillators into BTR5?
Impressive photo shoot. How about a discount code?

Could very well be one of the reason, though definitely not the only reason.

I think that Tidal MQA is only up to 96/24 https://support.tidal.com/hc/en-us/articles/115000397069-TIDAL-MASTERS
than you haven’t heard anything of what MQA can fully do. I think 96/24 is limit for non MQA certified gear.
My LG v30 unfolds MQA to 384k depending on original recording of course. I was hoping @FiiO would get inclusion of full MQA unfolding support for BTR5.

I don’t think I recall seeing any promises of MQA support... at this price probably not realistic? Do you know of any small dongle DACs that support full MQA unfolding? Helm Bolt is the only one I know of and that isn’t released yet...than you haven’t heard anything of what MQA can fully do. I think 96/24 is limit for non MQA certified gear.

@FiiO Is there any plan on a future btr6? Btr7? With better Bluetooth chip and processing power to deal with ease mqa, ldac eq, etc?

Audirect HiliDAC atom Pro and Beam 2 both support full MQA unfolding.
I don't think FiiO is gonna try to implement MQA into BTR5, just given it is ultimately positioned as a BT adapter first (which MQA will no work) and therefore there isn't much incentive for FiiO to spend extra money for license (which they have to pay on per unit basic).

BTR5K is more likely. However, FiiO usually keeps to a 2 years product cycle and given BTR5 was released at later 2019, we probably won't see an updated version by later 2021.
MQA doesn't actually need a new, more powerful BT process, as BTR5 already has an XMOS SoC that is capable of handling MQA. I think the problem is, as I said above, not enough incentive. Also, I said before, MQA is inherently not compatible over Bluetooth transmission because of transcoding. LDAC EQ will more like benefit from a more powerful BT chip, but as far as I know, the ToTL Qualcomm BT chip (QCC5xxx series) doesn't even has a software kit for LDAC yet (*I believe Qudelix is partnering with Sony to bring this happens). Even so, it will like require a custom firmware for EQ to work over LDAC, which isn't going to be easy as software isn't really their strong point.

The price in our Aliexpress store is now 128.79USD:https://www.aliexpress.com/item/4000316761086.html

Possible Bug report:
Perhaps someone could verify this on their equipment and report back.
On my setup (Huawei Mate 20 Pro - BTR5 - qJays IEM), sound volume is noticably higher on USB input, compared to BT specially with DSD material.
So much that, sometimes on USB I can hear distortions.
Using my ears and controls on my Neutron music player I need to reduce the USB output by 50% so that the volume would almost match BT.
anyone else noticed this?

Just to check, I assume you max out your smartphone's digital volume on both USB as well as BT and only control the volume using BTR5's volume buttons, or do you use smartphone's digital volume on BT as well?
