If anyone wants something from Hypex, I have an OEM account with quite a bit reduced costs. I'm placing an order soon and would like to save on shipping if anyone wants to throw something in.

Another quick project that did not go quick at all in the end: for my revised HT system I needed more amplifier channels. Nothing in recent classifieds would have worked from a size, performance or cost perspective so DIY was attractive again. I recalled Achim had an old blown class-D amplifier...

Sometimes an unexpected combination just snaps into place. This happened this week when I suggested to Achim we should perhaps try a class-D amp on his Soltanus electrostatic speakers. Sure, most folks associate ESLs with Martin Logan or Quad; each with their vices and virtues. The Soltanus is...

Interesting one, but I am looking for somebody who can attend an auction in Joostenbergvlakte on Thursday morning 16Feb since I am unable to attend myself: my beloved speakers were water-damaged with recent flooding, got insurance-claimed and prompty removed by their salvage company. I'd really...

Somehow I missed the remainder of Agaton's thread and since it's locked I'm opening it here. Maybe it belongs in Cable Talk though. First things first: forget about what protocols are involved. Same goes for switches. It doesn't matter what the audio transport protocol is, be it TCP/IP, UDP or...

Sometimes you just get that lemon. Always breaking, always something new. And during increasingly-impatient repairs, shortcuts otherwise not taken just make it worse. Herewith a saga of my Battle of the Active Tannoy. They say a mechanic's car is always broken. I can certainly profess to that...

INTRODUCTION: Unlike previous projects, this will be chronicled as it progresses and not after completion. It is the most ambitious and expensive private project I ever undertook, and progress is slow due to limited time between work, other audio R&D and family. The shortage of available...

https://audioxpress.com/news/hypex-presents-new-nilai500-diy-audio-amplifier-module It seems as a serious improvement and even more serious competition for Purifi's 1ET400. And, a new accompanying power supply will make things even more interesting. Now only to get the listening reports and...

This is one of my more ambitious DIY projects using tech and leftover parts from past commercial applications: a 500W/ch dual-mono integrated amp with internal DAC. In principle easy to do, cobble together an amp module, a potentiometer and a Chinese DAC kit and you're done. But quality will be...

A simple little project this time for some basic HT augmentation. This little board is powered from a 12V wall wart and responds on an opto-isolated 12VDC trigger input, in my application the trigger output of an AVP. So when the AVP is powered on the following is sequenced: 1. two buffered and...

Hi guys, I need a rough cabinet made for a single 15" coax test speaker. 40l volume rectangular box with a hole and a springclip. Anyone in CT that can assist, at a fee of course?

As per title: too many projects, too little time to give the subject the attention it deserves and no gear. Keen to start room treatments but need proper measurements of untreated room first from someone who's been around the block a few times. Very happy to compensate with some...

So with the advent of building my own 'audiophile' switch, it made sense to look further upstream in the network especially since other folks reported positive findings. From my internet router to the streamer are three switches, with the last in the chain being my own. No way will I put big...

Tried to find the earlier thread about it but gave up. Anyways, I wanted a little more airflow in my equipment rack. Not that anything gets overly hot as it is, but hotter than necessary and that reduces lifespan especially of switching amps and power supplies. Fan noise is a big nono though...

Got a bit of a problem: ordered a package from Amazon and is in transit. Then I got an automated "Customs Requirements" email from Aramex asking to complete clearance docs with a hotlink to http://onlineapp.aramex.co.za/Home/CustomsDetails/allkindsathings but when following it, it redirects just...

I'm looking for ideas: lighting and camera for macro photography, i.e. closeups of electronics. Nothing fancy and preferably not more than R3k, just better than a phone. Lighting alone will go a long way but a decent(ish) cam suited for macro would be great.

Calling on folks using these about a very peculiar issue a friend who recently turned into an audiophile is experiencing: his DAC streamer does not support Roon, so he's using mConnect with an Apple tablet & phone. mConnect is also what the DAC manufacturer recommends for Apple sources, and the...

Shamelessly ripping off the thread name from Agaton Sax , here's my take on an 'audiophile Ethernet switch' that's currently being assembled. While initially I didn't subscribe to these things, further reading up revealed some parts of the design that can indeed benefit from improvements. Some...

Hey guys, got a sad sad call from a friend with an octogenarian mother who apparently got a fiber upgrade directly from Telkom and now that she had to replace a broken phone there is zero ways to find out the wifi password. Who the service providers or other parties are is all unknown, "a guys...

Following up on the streamer, I reused much of the same stuff to build a proper external linear PSU for a Mutec MC3 USB I hounded Jessejon to sell to me. I saw online that many folks were doing this with good results and thought why not do the same as a spinoff from the streamer project. First...
