    FS [EU/France] - E1DA Cosmos ADC Grade B

    Hey Folks, It's time for me for some little upgrades. I recently received a long time awaited E1DA Cosmos ADCIso Grade 0. I put on sale my venerable Cosmos ADC Grade B, a state-of-the-art ADC that has been used for many, many measurements published here. Even in Grade B, it can already measure...

    ADC Recommendations for 3-Way Studio Monitors

    Hello everything is fine? I'm looking for suggestions for ADC components for use in 3-way studio monitors. I look for ADCs that excel in specific frequency ranges, aiming to ensure the best sound quality in each range. 1. For BASS, I need a carefully selected component that is capable of...

    Separate ADC units

    Hello! I am looking for Separate ADC interfaces with decent audio quality (at least better then Topping E2x2 input) for measurements and audio recording

    Cheap, Low Latency ADC

    Hi, I'm looking to record my bass/guitar- I have a Topping E50 that I'm very happy with currently and am looking for a portable and cheap ADC that is of decent quality. Not necessarily measurement quality- just one channel or two channels that are cheaper than and on par with most...

    Is Hi-Res Audio better because filter is outside audible range?

    Hi all, I listened to the Darko Audio podcast 10 hi-fi myths busted with Peter Comeau, and have questions about the first myth "Hi-res audio sounds better because of its ultrasonic content". I figured this would be the best place to get some straight, evidence based answers :) I know there will...

    Antelope Amari Measurements

    Hi, First review here, so don't hesitate to tell me if you see something odd. I just bought an Antelope Amari for mastering work and Antelope's specs were not precise enough to my taste. Since the APX555 was just there I did some measurements. I tried to be consistent with most measurements I've...

    Behringer ADA8200 Ultragain Measurements

    Here are my measurements of the Behringer ADA8200 Ultragain we purchased for the studio 6 years ago. Current price I see on Thomann Germany is 220€. The unit is digitally fed by our RME Fireface UC and analog I/O consists of a Topping EX5 and a Cosmos ADC. Let's start with the DAC part...

    Why we don’t see any bleeding edge process node mixed signal audio ICs, but might in the near future

    So, we all know about the AKM fire destroying a significant part of the semiconductor industry for more than a year. This factory obviously made more than just our beloved AKM DACs. The reason why we didn’t see these chips simply made by other foundries is that these chips are predominantly...

    Does computer power source (switching vs. battery) matter for a USB bus - powered device (e.g. ADC or DAC) ?

    I use a USB bus-powered ADC / DAC: Should it perform differently if connected to a typical switching PSU-powered computer, vs. a battery-powered laptop? The unit is a KORG DS-DAC-10R for digitizing records (or specific masters) not already [easily] available in 1’s and 0’s. I know - the KORG...

    Recommended USB interface? (ADC/DAC)

    Hi, I'm searching to buy a USB interface that I can use for two purposes: 1) Play HD music from a Raspberry Pi through usb and connecting the (line) output to an amplifier. 2) Record music from my turntable (through my iFi Zen phono preamp, so it needs to have a line input) to a Raspberry...

    Audio/Video distortion experiment: 1000x "I am sitting in a room"

    Found an interesting experiment: record a video, upload to youtube and then download/upload it 1000x to see the effects of video and audio compression. The initial experiment done ~2010 with a webcam. Big kudos to that guy, considering the youtube speed at that time it probably took many...

    Fiio BTA30 Pro

    I'm looking for a good Bluetooth receiver and I see the Fiio BTA30 Pro is probably a good choice. But I'm seeking clarification on the volume control method of the Fiio BTA30 Pro so I reached out to Fiio support and asked about the volume control method. The Fiio site tells that "the BTA30 Pro...

    Apple Dongle (USB-C to 3.5 mm) ADC quality with EarPods/free headsets

    I read somewhere years ago that perhaps crinacle used the apple dongle's ADC via an adapter to measure equipment because apple dongle's ADC is the best of all USB-C dongles. I think this is true. It is not studio quality, but it does support 24/48 PCM recording in mono and does not have as much...

    Standarized Measurement Protocols for E1DA Cosmos ADC owners

    I've just recently acquired mentioned ADC. It's great and precise tool for its price. I come to idea it will be nice to have unified measurement protocol for owners of Cosmos, so everyone can contribute with measurements of devices which Armir due to different reasons can't measure (distance...

    Quant Asylum QA403 with ESS DAC and ADC

    https://forum.quantasylum.com/uploads/short-url/e9EUxkUod8AstX3q4DM5uLsmMNL.pdf That didn't take long for them to replace the QA402. THD measurements in loopback and from external source look okish but those converters are capable of much more as demonstrated by several DACs tested here and of...

    Swissonic Converter AD 24/192 (ADC) Measurements

    After the recent measurement I did for the unbranded ADC I got off eBay, to compare a friend borrowed me a relatively similar device by a thomann.de house brand - Swissonic Converter AD 24/192 that sells for about 40€: Basic features are mostly the same, except this one comes with a power...

    Unbranded ADC from eBay - measurements

    Recently I was looking for a cheap ADC and found a generic, unbranded one on eBay for just under 10$ (UPC: 6927373037416). Here's a few pictures of the device: My plan was to use an ADC to connect my turntable to a digital input of miniDSP OpenDRC-DI, but I didn't really want to spend much on...

    Field Recorder Comparison Sony PCM-D100 vs Olympus LS-11 (vs Motu M4)

    I recently treated myself with a Sony PCM-D100. The price was just too good. Here is a quick ADC Line In comparison with my Olympus LS-11. The measurements were done in REW V5.20 RC8b with a Motu M4 using the unbalanced monitor output (Output 1 RCA) which was connected to the Topping L30 so...

    Unconventional Stereo System Issues

    So, earlier today, I encountered a really catastrophic issue regarding my unconventional stereo system. I connected my Victorola TT (https://www.amazon.com/Victrola-Bluetooth-Suitcase-Turntable-Speakers/dp/B00UMVW4VA) to a phono pre-amp...

    A brief history of DAC and ADC chips...

    This started out innocuously enough in a post around these parts, now it has become a fairly comprehensive overview of high-end and midrange converter chips with some performance figures from the '90s into the present day, and even a few links to papers and the like are included along with some...
