Building a reference system - Part 2: Glenn's headphone amplifier

Posted by Amine Slimani on October 21, 2014 at 2:25 PM Comments comments (2)


The story of Glenn’s OTL headphone amplifier started as that of a relentless endeavor to make the ALO recabled Beyer T1s sound as good as it was possible, and ended up being that of finding the center piece of my system that will probably outlast many other major components.

At the time of the pur...

Building a reference system - Part 1: Metrum Octave MKII NOS DAC

Posted by Amine Slimani on October 10, 2014 at 5:10 PM Comments comments (1)

Many audiophiles believe that the source is the most important piece of equipment in an audio chain. Indeed, if information is missing from the source, there is nothing that even great preamplifiers, amplifiers, speakers or headphones can do to recover it and add it back to the chain. Conversely, if there is so...

Building a reference system - Introduction

Those who have visited before might have noticed that I haven’t written any new article for more than two years. How did that happen?

Part of the explanation is that I was busier than usual with non-audio related things but that was not the main reason for this disappearance. The main reason for my taking away a brea...

As I was looking to upgrade my headphone amplifier for the ALO recabled Beyer T1s, it was clear that I needed to get a tube OTL amplifier as recommended by many people who have tried that combination.


While I was about to order the Woo Audio WA2 (OTL amp based on 6AS7 / 6080, I was lucky enough that Stavros (rosgr63) pointed me towards Glenn who makes some very interesting t...

Review: Reference Tweaks Miracle Wraps

Posted by Amine Slimani on July 24, 2012 at 9:30 AM Comments comments (1)


When nenno from Reference Tweaks first contacted me about his Miracle Wraps, I was very intrigued to say the least. I did not totally understand how such a “tweak” could have an impact on the sound, but since different cables with different shielding schemes have sounded different in the past, I agreed to do...

Review: Kingrex UD384 USB DAC (32bit/384Khz) & UPower

Posted by Amine Slimani on February 4, 2012 at 1:55 PM Comments comments (4)

Do we really need 32bits/384kHz capability in a DAC? That is the first question I asked myself when Christine from Kingrex asked me if I were interested in reviewing their newly released UD384 usb dac. It is until recently that 24/96 and 24/192 have become more common but there is still a long way to catch up with the choice of material released in the 16/44 RBCD forma...
