This time it's personal

We can never hear all the gear. No stereo can ever be the ultimate as next year's entry level model will blow away this year's reference model (as is always the case). We can never know if any recording is accurate to any given benchmark. Measurements are sometimes useful but ultimately incomplete. We can never know what someone else hears or for that matter, why they hear it, too many personal and environmental factors to take into account. The pursuit of greater audio can only b

Moving on: An inexpensive ($20), but high quality, LPSU for my Regen cascade (warning: some DIY):

After recently finding a (used) UpTone Audio MMK kit for a very nice price, I now needed a good LPSU for my Regen cascade, so the existing supply could be removed and used for my Mac Mini (as originally intended). I didn't want to wait for the up-coming UpTone "whatever-it-is" regulator. But the idea of a separate regulator module and a cheap raw supply sounded like a very good idea, so I looked around to see what I could find to combine it with parts I have hanging around and a little sweat equ

Powering a Regen cascade - one possibility (a 65VA eBay LPSU), including the 12V dilemma

Note: I started writing up this project in early October 2015, as I was assembling the parts, but it has taken all this time to complete and refine the text for publication (it was not my highest priority, but worth completing).     1) The Regen cascade   My USB cleanup cascade is made up of two UpTone Audio Regens connected in series between my Apple Mac Mini and Benchmark DAC2, with both powered by a Chinese linear PSU.   I was lucky to get one of the last of the first batch of Regens

"Temporal Deblurring", Deconvolution and what MQA Might Be

Introduction The application of deconvolution to signal processing dates back to work by MIT's Norbert Wiener during the Second World War. https://en.wikipedia.org/wiki/Deconvolution https://en.wikipedia.org/wiki/Wiener_series   Deconvolution is widely used to deblur signals in both the spatial and temporal domains. http://alumni.soe.ucsc.edu/~htakeda/VideoDeblurring/VideoDeblurring.htm   End to end deblurring of an audio signal can be performed by deconvoluting the signal with a measured

Thoughts about digitising vinyl...

First off, you have to ask yourself "Why do I want to transcribe my vinyl?" Do you have a collection of vinyl which is rare and unavailable in digital formal, or are you hoping to get better quality than you can get from CD?   If the latter, then you need to start from a point where you have good quality playback equipment and clean vinyl. Anything else is just trying to polish a turnip ... whatever you do it will still be a turnip. So with that in mind, do you have a vinyl playback system

Roller-type Vibration Isolation Devices info for audio

In this BLOG post I'd like to focus on only the roller type Vibration Isolation Devices (VID). I'm not a big fan of springs, cones, or squishy things, as I believe them to only really operate as filters, shifting vibration from frequency to frequency with little real attenuation. I think that the roller type devices are qualitatively different, true isolators rather then just filters. Note that this type of device will only islolate horizontal and radial vibrations.   I wanted to share inform

Upgrade GPU for more CUDA processing power

I built a new low acoustic noise machine for using HQPlayer on Windows 10 with exaSound e28 DAC (8 channel). This machine is currently based on Gigabyte GA-Z170X-UD5 TH main board for their Ultra Durable series. It has USB 3.1-C / Thunderbolt among all kinds other very recent features. CPU is Core i5-6600T (35W TDP) and RAM is 32 GB (4 DIMMS) of Kingston HyperX FURY Black DDR4 2133 MHz CL14 and passively cooled Seasonic Platinum 520 Fanless PSU.   Since the drivers for Intel GPU built into the

Listening to music on the Hi-Fi

I don't think I qualify as a typical audiophile or if I do, it stops short of most of the expected characteristics people associate with audiophiles. I have an especially hard time using the lingo to describe the sound of my components. I think it deals with what Michael Lavorgna of Audiostream commonly refers to "listening to music on the hi-fi".   I don't really listen to the hifi itself so its hard to tell you what it sounds like. I listen to the music. The stereo is just a delivery method

Genelec - What is the rave about?

OK, I'm a Genelec fanboy. You know that if you are a regular at CA.   Do they really sound better? Are Genelecs for everybody? What is the secret technology?     Do they really sound better?   Genelec stands out as the best monitors for money (IMNSHO) because they just sound invisible. But it is not magic and as any other system, they sound best when you feed a great signal and place them wisely in a treated room. Just like anything else.   But that is where the "Just like anything

5.1 + 7.1 through HDMI from GPU graphics card

Well,just had the time of my life trying to setup my new system or should i say the audio through the HDMI of the GPU to the receiver.I tried always possible with the help of anwaypasible and i was about to give up and call it a day.I went through the settings on the AV receiver and found the solution in the HDMI settings.If you come across this yourself switch o the TV in the AV receiver in the HDMI.

alsa-capabilities: reveal formats and sample rates your USB DAC supports

Hi,   For your convenience (and mine) I've created the `alsa-capabilities` script, which shows the available alsa interfaces for audio playback in (or connected to) your linux computer, including USB DAC's, and the digital audio formats and sample rates each sound card or external USB DAC supports.   You can run it straight from the web, by copying and pasting the following command in a terminal screen: bash <(wget -q -O - "https://lacocina.nl/alsa-capabilities") ## or bash <(cur

mpd-configure: generate a bit perfect mpd configuration with a single command

Hi there,   All those new (and maybe even older) to music player daemon (mpd), linux and alsa, I've published a free script which with a single command generates a configuration file for mpd, which turns it in to an bit perfect music streamer.   The only requirement is that you have a working linux installation with mpd installed. After opening up a terminal screen, paste the following commands to generate and display a mpd configuration. When multiple audio cards (including USB DACs) are fo

Analog vs. Digital Definitively Answered, Once and For All!

OK, maybe not, but hear me out. I think I found the break-even point between Digital and Analog in my system, and I think it's an interesting data point for some who, like me, have spent years and years and years and countless 10s of $1000s wondering how good my digital system sounds in the grand "scheme," and how much better can it sound, and at what cost? And when the F are people going to stop suggesting I should try vinyl?     DIGITAL OR DIE   For the record (no pun intended), I'm a d

Some analysis and comparison of MQA encoded FLAC vs normal optimized hires FLAC

Now since there are MQA encoded FLAC test files available, I wanted to see how the file works out without MQA decoder - as a normal FLAC.   If we first look at the original 352.8/24 (DXD) file that has FLAC size of 69 MB:   We can see that there is content up to around 57 kHz.     If we then convert it to 44.1/24 we get a FLAC with size of 14 MB:   From the filter roll-off we can see that there's quite a bit less than 24-bit worth of infor

Review: iXsystems FreeNAS Mini: A Plug-and-Play ZFS NAS that doesn't suck to set up.

Like many here, I try to keep computer audio simple. My music library resides on a single external bus-powered Oyen firewire drive. Until recently, this was a 1TB Samsung HDD. I've now replaced it with a 1TB SSD, but what is of relevance here is what happened after about three years of constant, daily use. Like many drives (HHD and SSD), it started to fail. However, it wasn't obvious to me, at first, that the hardware was failing. I am still not certain. When I copied the contents of the

Very basic home networking question.

Comon now- actually your phone will probably stay up during a power outage, because the switches should be on a UPS designed to stay up during power outages and catastrophic events.   Nothing is going to work forever in a fire, but units powering emergency services need to be identified and given special treatment.   I have UPS power from my computer room runnkng to evry floor of our building just to power the switches that power the phones. Makes 911 service available even during a power

Analog vs digital volume control - case study with Mytek Stereo192-DSD DAC

There has been a lot of discussion about different types of volume controls. For comparison purposes of one case I chose to use Mytek Stereo192-DSD DAC which has three different volume control modes; analog, digital and bypass. Signal routing is implemented using relays. DAC chip is ESS Sabre ES9016S in stereo mode (4 DACs in parallel per channel). ESS Sabre has 32-bit volume control and internal DSP pipeline so it has 8 bits more resolution than allowed by 24-bit external input. It also has hig
