Try a signal generator and see what your upper limit of hearing is.
Bet you can't hear 15k at all.

Frequency response while streaming stops at 15kHz- did I miss something in the fine print?
I am streaming with Qobuz. It sounds great playing both CD quality and hi-rez music. So what's the trouble? While working to get the bass response in my room just right I found test tracks on Qobuz. This was very handy as I played 30-60 Hz test tones over and over. So when I was done with that I streamed a pink noise track and pulled up the FFT analyzer app on my iPhone. Surprisingly, I see the trace drop straight down to 0 dB above 15 kHz. I streamed some test tones and confirmed that above 15 kHz nothing is happening at the speakers. In my old and decrepit state I can no longer hear above 15 kHz so I am relying on the app. In a panic that something is wrong with my speakers I pull out my vinyl test record. I have a nice, pretty flat frequency response from 20-20 kHz showing on the FFT app. I put in a test CD and again show a good 20-20k. Lastly, I ripped the test CD onto my server and again had a good 20-20k response. So why did I not know about the limited bandwidth while streaming? Is it just me? It is an abrupt cutoff above 15 kHz while streaming. What's going on?

P.s compressed music can sound mighty good indeed if it's been compressed thoughtfully from red book or high res. You can lose very little quality, especially with a DAC that upsamples well. However if the recording is poor and compressed from the get go you will notice. Recording quality is orders of magnitude more important than digital compression. |
p05129, go back and read what I wrote. There's nothing between the lines that said I stream anything. There's that qualifying phrase, The closest I've come to it is with using some nice active speakers with a built in DAC taking it directly via USB from my Mac. I only listen do casual listening and it's really not bad, either with my stored music or with internet FM listening. But it pales compared to my CD based rig and I'm not about to dump lots of money into something that's changing and improving as I write this. The process would drive me crazier than I am now. 😀Like others here who've already pointed out, it's really expensive to have a great sounding streaming set up. Lots of online reviewers have been saying that for a long time now. All the best, Nonoise |
