The one mentioned above I did manually, but the one behind the spoiler below used the level step feature. The graphic however was produced with gnuplot because REW did not show THD+N vs signal. Attached are the REW mdat file, the export file from REW which contains the data, and the script which created the graphic from the export file. I'm sure one could also use Excel or any other spread sheet program to create nice graphics.You mean like this measurement behind the spoiler here? I'll check later how I did it, but REW not long ago got the feature to do level steps.
I am thinking what is better:
iPhone/PC ==> Bluetooth AAC ==> this Receiver => Toslink ==> DAC
or
iPhone ==> AirPlay2 ==> Belkin Soundform connect => Toslink ==> DAC
The latter choice will be fully lossless, assuming your source material is 44.1khz/16bit and the Belkin device doesn't do any wacky resampling or screw things up in other ways. To clarify a bit on how AirPlay works for audio streams:I am thinking what is better:

Mods, feel free to delete this post if it's too off-topic. I feel it's relevant because people are evaluating high-quality wireless solutions such as LDAC via BT and are weighing it against the alternatives. But, no hard feelings if you disagree.The streams are transcoded using the Apple Lossless codec with 44100 Hz and 2 channels symmetrically encrypted with AES
[...]The protocol supports metadata packets that determine the final output volume on the receiving end. This makes it possible to always send audio data unprocessed at its original full volume, preventing sound quality deterioration due to reduction in bit depth
Yes but if your source is 1m away from the device, being BT or WiFi, what would you choose?
In addition, with Chromecast Audio (CCA), your phone (or whatever you're using as a controller) is not the source of the audio or audio stream, so the CCA's audio signal is not impacted by the strength of your controller device's WiFI signal or its proximity to your CCA device. These factors (in addition to multizone and others) means that this device can't compete as a direct replacement for Chromecast Audio.This is a bluetooth receiver and doesn't do any wifi/multi-room stuff like the Chromecast audio does.
My strange subjective experience with AirPlay1 is that my Denon AVR sounds weird with it (probably Denon or my configuration fault), and I hate the delay between a selection and actual playback.definitely the later.
I explained that it the other thread and there is nothing funny about it. A pure tone at 1 kHz is a very simple signal that all lossy codecs need to handle with ease. It is not outside of the scope of the encoding of any of them. After all, I can decompose any music into corresponding tones and 1 kHz would very well be one of those tones.@amirm I think it is pretty funny, that you are passing judgement on lossy codecs by using testsignals (not music), considering your remarks on the MQA threads.
If only we could transmit in LDAC from PC. Couldn't find any dongle like that.
Well, that seems like huge a waste, I was looking for a purely digital solution. All I found is that on Linux using pulseaudio you can transmit LDAC with any bluetooth dongle. Also fiio m5 seems to be able to do this in DAC mode.There's a fair number of such transmitters that accept optical or analog connections.
By modulating the noise floor.How does LDAC compress if it has perfect fr?
