Release Date : October the 6th, 2005

- new1.gif (897 bytes) JJ TESLA has been known for years for its involvement in valve audio.. Have a look on our new section on this serious manufacturer.

- 'Cleaning Brushes for Tube Sockets' is about to become an MTZ audio 'best-buy' product. If you operate a valve amplifier it might be a good idea to have a close look..

TSB_TAG_photo.jpg (46586 bytes)

 

- Also if you like making your own DIY projects and using a soldering iron, our ' Felder' high quality solder is something more than a good choice. If you contact us we will be happy to give you more than one reasons to give up typical 'amateur' solder and enhance all your critical 'earth' connections..

An improvement of several dozens of milliohms might seem unimportant to you..

But every time your power supply rectifier diodes switch on to pour several Amperes to your filter capacitors (and from there to your speakers), you will not only measure the difference in voltage regulation but hear it as well !

There are dozens of good amplifier schematics ensuring high power and minimal harmonic distortion.. yet none will deliver an exceptional damping factor when you are done implementing it if you have not gained an expertise in making adequate ground lines. Soldering is an art itself..


Release Date : September the 2nd, 2005

After a short break for summer holidays we are back ready to launch our top floor standing two-way speaker project, ARCOS X. Listening sessions as well as fine tuning have already begun.

new1.gif (897 bytes) Having understood that most software on low frequency speaker simulation ignore mutual acoustic coupling between multiple woofer drivers as well as that between driver and port, we are ready to include this feature in our LFA software..We expect to launch new version 5.5 on December..
