Do you think there is a problem with the CSR8675 chip? In the end, LDAC EQ worked on UP4 sort of.

The Hidizs S9 PRO is pretty ugly compared to the FiiO, especially with that bump at the top.

I am attracted by S9 PRO's sound but not its outlooking.

First, UP4 does NOT support EQ over LDAC. Secondly, it is not a problem per se on CSR8675, but simply because it is an outdated chip that is too slow to process EQ and LDAC at the same time.

Don't need to buy the new one, its an alternate due to production issues (chip shortage).
If you wanna buy a new one, its better to save up a bit more and buy an upgrade.
The dude above ended buying Ifi XCan which in some aspects are one step above BTR5 and have more powah to run Headphones.

Btr5 in dac mode + xcan= 
1000mW instead of 225mW
I still need a dac for my xcan.
Maybe btr3 is a good thing, don’t need the power anymore

Aptx only, same for the xDSD - if this is important. But yes, both sound good wirelessly.
The form factor is different. The price is different too)

Plan too use it with a good tiny DAC
It needs 2v in

But iFI XCan is an Amp only, not a DAC...
This is a Bluetooth DAC/amp too on the ESS Sabre chip.
No dac is good. Never goes obsolete
Dac does.
Dac does.
Introduction to FiiO's Product Line and Update Plan in 2021--From James
Chapter 4 BTR5 2021, the GOAT!
Since the BTR1 was launched three years ago, FiiO has started its plan of conquering the bluetooth amp market. From BTR1, BTR3 to μBTR and BTR5, each of them has become a hot cake in the market. This production line can be praised as a success with hot sales and good reputation at home and abroad. What’s more surprising is that the BTR5, with higher price than BTR3, has managed to increase sales volume significantly.
The chip shortage has become more and more serious since 2021, the production of BTR5 hasn’t become an exception even if it doesn’t use chips from AKM . The supply of the chip that BTR5 used was promised by ESS Technology before, so we even placed an order for over hundred thousand Yuan. However, due to the limited capacity of production, ESS Technology can only prioritize the production of the chip with higher price, the ESS9219C, instead of the ESS9218 for BTR5.
In light of this, we had to start the BTR5 revision plan three months ago. Since the BTR5 is our main force in great market demand, we can only make as few changes as possible in order to resume supply as soon as possible. Other plans, for example extending battery life and adding 4.4mm port, are thus failed to proceed but to be delayed until 2022.
Compared with the old BTR5, the BTR5 2021 is mainly upgraded by a better DAC and support for MQA, which contribute to greater performance. In addition, conforming to the rising tide of Apple's high-definition lossless, we have specially introduced the BTR5 2021 L-C. It comes with a Lightning to Type C data cable in order to facilitate the users of Apple mobile phone.
At the same time, a convenient charging shutdown function has also been added for mobile phone users to avoid charging the device’s battery when the mobile phone is connected.
Appropriate usage scenarios
There are many occasions that we can make use of the BTR5. For one thing, it can serve as a bluetooth amp when connected with a mobile phone and play music via bluetooth. For another, it can connect to the mobile phone through a wired way as a dongle to provide higher-quality music. Besides, it can also be used as a mini portable amp, and to connect to PC/notebook and other digital devices.
The BTR5 2021 is suitable for users who have higher requirements for sound quality and portability. It is usually used with mobile phones.

Hello everyone! I recently bought a BTR5 but I noticed that connected with a USB-C cable to my Smartphone with the FiiO APP when I hear the music in DSD 64, 128 and 256 there are strong BUMPs when you change tracks, pause, resume play , etcetc ... any of you have this problem? Thanks
Dear friend,
Does the issue happen when playing PCM music files? Which app are you using? You may try to switch the usb output option to DOP to see whether it helps?
Best regards
thank you for your kind reply ...
with Flac and DXD songs it doesn't happen, only with DSDs set to "Native" with the FiiO APP player
If I put as USB output on "DoP" the noise is lowered a lot, an audible "click" remains but much lower
However with the "DoP" setting it does not read the DSD 256 says that the "format is not supported"
However, I got the BTR5 because it natively reads DSDs up to 256, so I really hope to solve it otherwise I'll have to return it
