Portable Bluetooth DAC - Would that improve SQ? What would be the best solution?

For me Bluetooth (BT) makes everything more convenient - cable is not an option.

After BT 5.2 has hit the market with new products I bought:

  • Astell & Kern AK UW100
  • Beoplay EX

I use them in my home office and on the road with my iPhone 11.

I my home office I use them in combination with Roon (Roon installed on a cirrus7 nimbus with Windows 11 - (Roon Server - NAS QNAP HS-264) and a BT 5.2 transmitter (Creative BT-W4).


I was reading about



The Q is would such a device or any other devise improve the SQ?

THX for any advice :slight_smile:

That’s for connecting wired headphones to a Bluetooth connection. It’s not going to improve anything if your using Bluetooth headphones as it won’t work with BT headphones.

Good to know :slight_smile: THX :slight_smile:

Is there any other way to improve SQ in my setup? Not than I am unhappy with SQ - just looking for way to improve things :slight_smile:


The best option will be in not using BT :wink:


That is not an option - I don’t see any need for that.

That’s how you improve SQ.

BT 5.2 doesn’t really bring much in the realm of increased bandwidth. What you need to explore is devices and headphones that support ‘better’ codecs like Aptx HD, aptX Adaptive, LDAC. LDAC is the best option but little supports it.

Good luck in your quest. It’s going to be a good long while before BT can beat a copper cable.

I use this. It’s fantastic but requires wired headphones. 5K DAC AMP – Qudelix, Inc.

Thats why I bought Astell & Kern AK UW100 and Beoplay EX - only LDAC is missing.

I know copper cable is better - but for me not convenient :slight_smile: I don’t want be stuck in a place due to the cable :slight_smile:

I could “live” with a cable solution (from earphone to DAC) if there is small portable device like FiiO BTR7, iFi xDSD Gryphon … that would improve SQ compared to BT earphone
