    Advice on choosing an amplifier (Speakers: Elac DBR 62, Sources: Digital Music Library, Record Player)

    Hello, first of all, this is my first post on this forum so I apologize for any mistakes. If I am not asking my question in the correct sub-forum please tell me. I recently bought a pair of Elac DBR62 speakers since they fit in my budget range and were recommended on this website. Now I need...

    Question about debunking of myth that higher sampling rate increases time accuracy

    (The whole video is great for people who want to better understand how digital audio works) He talks about how you don't need to have a sample at the start point of the sound - i.e. that the start times of sounds aren't quantized to the sample rate. I totally get that and his animation is...

    Strange discrepancy between REW FFT and Audition FFT

    When generating sine tones in REW, exporting as WAV, then analyzing in both Audition and REW, the results are identical: However, when I generate and export the tone in Audition, then run the FFT with both programs, it looks like this: Where do these spurious tones come from? Here's the 1k...

    Seattle-area audio experts for hire?

    Hi, we have a recording studio set up in our home in Seattle which includes a PC for recording and playing back audio. We had a dedicated power circuit installed for all of our gear. We noticed that when we plug the PC into the same circuit as the other audio gear, we get a lot of digital...

    Building a perfect headphone system.

    Hello fellow ASR members, I'm looking for advice with respect to building a headphone system. Although my Activo DAP sounds good, I want to build a "reference" headphone system so I can easily quantify (at least subjectively) different headphones as I buy more in the future, based on perceived...

    Considering getting a DAP or better android dongle

    Hey fellow members, I'm considering getting a DAP or better android dongle. I currently have the CX-PRO Audio 31993 384/32. I bought it from amazon for about $20. I listen to CD quality music, not mp3s. So lossless sources, as i'm told by friends is the way to go. I have a pair of KEF M500...

    Digital effects for tube and/or analog sound?

    What are the best (preferably standalone) digital effect units for experimenting and listening with different "sounds" (tube or "analog" sound) on your otherwise transparent hi-fi system (where the audio comes from digital sources) ? Would you use some stereo guitar effect/multi-effect units or...

    What is the best method to play back digital stereo music on an AVR?

    Like the title says, What is the best method to play back digital stereo music on an AVR? I used to be a major DSD & high-res freak but now I am perfectly happy with CD quality music. I have a Sony STR-DN1080, which I am fairly certain it can reproduce CD quality music well, Anything above CD...

    Ground Loop / USB output noise

    I'm hearing ground noise from my PC source. It's a custom tower PC, which through a Apple Type-C to 3.5 mm, connects to a Schiit Asgard 3 which powers my HE-4XX headphones. Noise is source-agnostic, connecting to mobile devices removes the noise completely. While PC headphone out, or USB ports...

    Equalizer settings (mine) - Do you think my hearing is broken?

    So this is what my EQ setting on NW-A50 Series Walkman has looked like for the past few years and everything sounds “just right”, do you think my hearing is broken? The one in image (Custom 1) is for over-ear headphones, but the saved IEM equalizer setting (Custom 2) looks identical except -2dB...

    Digital Conversion

    Hello everyone, this is my first post here. I've recently put together a project for personal enjoyment which consisted of an ESS DAC chip feeding into a few op-amps. This would then plug into my computer through the help of a TI USB controller, and then into my headphone amp or speaker amp...

    Just for fun: hypotetic ideal stereo digital audio streaming?

On the basis of...

    Question about sampling/PCM/Nyquist

    Got into a discussion on another forum. Trying to see if a user‘s claims have any theoretical merit. So, Nyquist states that if you sample >2x the frequency range you want, it can reproduce that range perfectly (with quantization noise). However, what if there was a super short transient (say...

    An Android device as a touchscreen network streamer...

    A few days ago I stumbled across a video of Darko discussing using an LG V30 smartphone as a network streamer. Since I don't trust him very much, nor do I care for his presentation style, I decided to experiment with the idea myself. By the way, the following site conducts some performance...

    "The brains, a Broadcom BCM2711 system-on-chip, features four 64-bit Armv8 Cortex-A72 CPU cores clocked at 1.5GHz, a step up from the A53 found in the Model 3 B+. The Raspberry Pi Foundation reckons its latest shiny-shiny is comparable to an entry-level x86-based system and we’d have to agree...

    Do we need audio reviewers, and how they should they review products?

    Do we need audio reviewers? (My answer is yes for what it is worth). How should they review products? (Ahhh, here is where it gets interesting I think).
