Cheap AptX HD receivers with decent analog stage

Hi All,

Are there any Bluetooth receivers with AptX HD support, analog output and external antenna (for a longer range) fitting into the USD30-40 budget that are known to produce better analog sound quality than the rest of those in this modest price range? There are sooo many on the market that it's really hard to choose any particular one purely based on their advert descriptions alone. Currently looking at something like this one for instance:
CSR8675 Bluetooth 5.0 RCA Receiver APTX HD RCA Bluetooth Music Audio Wireless Adapter for Car Audio amplifier-in Wireless Adapter from Consumer Electronics on AliExpress

or this one:
262ft/80m Long Range Bluetooth 5.0 Transmitter Receiver 3 in 1 Wireless Audio Adapter Low Latency aptX HD Spdif RCA AUX 3.5mm TV on AliExpress

Unfortunately I have almost no background in radioelectronics and am really bad at soldering, so modding any of them is not an option.

Previously after researching this forum I bought a couple of USB DACs w/o BT to try - DA3 (SA9227+PCM5102A) and an unbranded CM108+4xTDA1387 one - and tbh couldn't complain on their audio quality in my application (a Denon PMA-355UK amp and a pair of hardly known Radiotehnika S90 speakers made by RRR in Riga, Latvia in the 70s-80s, used mostly for outdoors listening in a very quiet place on the nature). So I suppose I need something like those again now, just with CSR8675 or similar for AptX HD.


Many thanks in advance!

The BT receivers with analog outputs have a dac inside them to convert the digital data to analog. Do you care about sound quality at all, or it doesn't matter much for your application?
Well yes I do as long as it doesn't drive me into the hundreds of bucks zone: my amp+speakers may just not be good enough to sound that much different, else I'd probably go right for something like Topping D50s.

Btw I've just read that CSR8675 has a built-in DAC functionality, however decent DAC designers bypass that and feed digital egress (sorry for the terminology) into decent quality standalone DAC chips.
 
noise floor. more ££ dacs have far better noise floor. its something i am worried about too. this is a decent brand New Avantree Oasis Plus Certified aptX HD Bluetooth 5.0 Transmitter Receiver for TV, Low Latency Wireless Audio Adapter|Wireless Adapter| - AliExpress i like to think is has a ok,good enough low noise floor. that i will be happy enough and can live with it. its £25 cheaper ordered from china than in the uk!
you can get use optical outputs on cheap recivers and then use your own optical to analog dac or if your amp has optical or spdif (via optical to spdif coxal converter) input, connect BT receive into amps own dac.

cacao ambiance: sorry just noticed it - thanks for your reply. When I last browsed the market I noticed some devices with AptX-HD+LDAC support costing just above £40, like this one. No idea about their noise floor though... would be great getting one of those as long as they have a reasonable noise floor like the one you're referring to, which btw seems to be getting quite high customer feedback so far.
