soundcheck's Purifi amplifier

Let's talk a bit about amplifiers. I owned numerous devices. Commercial and DIY. Jeff Rowland, Anaview Abletec, Hypex,  T-amps, SMSL and the list goes on and on. I tried many of those ebay Class-D modules. I tried all kind of power supplies (connex/hypex/linears, ...), I tried several full digital amps. and I compared these to even more amps owned by audiophile friends of mine. 

Oh dear. What a career. I swapped Class-D output transformers with Mundorf coils, replaced rectifiers, cabling, fuses connectors, power cables and the tweak list goes on and on.

And finally I got hooked up to a  Purifi Audio Eigentakt 1ET400A Stereo Eval1 amp integrated into a Ghent Audio case.

I am running this amp for more than a year by now. Puh. What a journey.

Gustard V18 vs. Allo Katana - a 2022 assessment

For almost a year or so I am running an IMO excellent Gustard A18 DAC.  The Gustard builds around the top of the line AKM AK4499 and Accusilicon clocks.  The DAC received quite some nice reviews confirming my experience with it.  Most reviewers saw that DAC challenging much pricier rivals. Until now I was never in doubt about the overall DAC performance...

The RPI foundation finally officially announced the release of RPI OS 64.

audio@advise passes 1.000.000 site visits

Hey... 

...just figured that the site visit counter of blogger passed the 1.000.000 for audio@vise!!!

I thought it'd be worth mentioning. 

sKit and pCP81 - regression test successful

On December 5th  pCP 8.1 was released.

I just did a sKit regression test on my RPi4. I used the 64 bit version.

And I did a maiden installation.

It all went OK. Not a single hiccup! Great.

Releasing sKit-custom-squeezelite.sh 1.4 for test

I just uploaded a seriously modified version 1.4 of sKit-custom-squeezelite.sh

(UPDATE Nov-12-21 - I uploaded 1.4.2-beta. It comes with a few minor corrections, slightly enhanced stability and traceability)

squeezelite - update - flac processing improvement

 Hi there.

Just recently a small - potentially interesting - performance enhancement for flac processing had been introduced.

Those of you who run sKit and a (my) custom squeezelite binary should update the binary.

I did update my own squeezelite branch on github accordingly.

I havn't tested what the update does - performance and soundwise - though.

If you run the update and experience some improvement - please let me/us know.

Enjoy.

Hi there.

I uploaded a new version (1.5.) of sKit.

Full Digital Amp News

In 2012 I wrote an article about Full Digital Amps. I just updated it a little.  That's one part of the news.

During those days I was trying and tweaking several of these FDAs. I really liked the technology and the idea behind it. And they sounded extremely clean and dynamic already back then. IMO cleaner and more dynamic then most DAC-amp combos I had listened to. In the article I describe what I didn't like and why I left that idea alone. Just to mention it: It was mainly due to the mediocre digital pre-stages of these amps. These amps also need top notch USB receivers, filters, clocks, DSP/SRC, power supplies, regulation, layouts, isolation etc. During those days that's IMO been a major weak spot. 

I still kept watching for developments. Not much was happening over the years.
