Rob Watts on listening tests

March 28, 2016 ohm

Chord Electronics's legendary designer, Rob Watts, has finally penned his first Headfi Blog post - and tackled the tedious: listening tests.

“We are listening with recordings for which we do not know the original performance, the recording acoustic environment, nor do we know the equipment it was recorded with, the mastering chain, nor the source, DAC, amplifier, HP or loudspeaker performance in isolation. We are listening to a final result through lots of unknown unknowns. I can remember once hearing an original Beatles master tape played on the actual tape machine it was recorded with, using the actual headphones they used. It sounded absolutely awful. But then I was also lucky enough to hear Doug Sax mastering at the mastering labs - the equipment looked awful - corroding veroboard tracks on hand made gear - but it sounded stunning. So we are dealing with considerable uncertainty when doing listening tests. Its even more of a problem when designing products - how do you know that you are not merely optimizing to suit the sound of the rest of your system rather than making fundamental improvements to transparency? How can you be certain that a perceived softness in bass for example, is due to reduction in aberrations (more transparent) or increase in aberrations (less transparent).”

A negative Fiio X7 review

February 18, 2016 ohm
Fiio-X7.jpg

With the exception of Fook’s review, the consensus at Head-fi is that Fiio’s X7 is a game-changer. Fook painted the X7 as 'not able to drive transportable headphones', which I seriously doubt. But he took issue with items that I consider incredibly important: jumpy interface and software quality.

For non-rockers - Grado PS1000

February 5, 2016 ohm

Flagship headphones don’t interest me. I’ve gotten on fine, and for the foreseeable future will get on fine with Beyerdynamic’s DT880/600. But, slowly, I’m becoming a Grado head. I love the RS series and the SR60. The GR10 is my favourite small-fit earphone and the GR8e is a brilliant follow up to the earphone that changed my mind about the company. Yes, the original GR8.

Geometric porridge to the Essence HDACC

January 26, 2016 ohm
Grind baby, grind!

Grind baby, grind!

Reviews where I don’t bag physical flaws here, ergonomic oversights there, are very few and far between. Put simply, perfect products do not exist. So, when Essence's head, Bob Rapaport, insisted that the unit he sent for review was perfect, and by corollary, the phsycial flaws I noted were the products of my imagination, I decided to unpacked the HDACC again and take a few reference images. Snap, snap.

Titan 3 and 5 - Dunu about the finish

January 20, 2016 ohm

A bevy of grammatical mistakes didn't bar the publish of my Dunu Titan 3 and Titan 5 review at Headfonia. And, while I’m probably as negative as I’ve been for a product whose sound I really like, I hope you’ll see a method behind the grammatical madness.

Eyes on Jupiter - Campfire Audio's case for patience

January 15, 2016 ohm

Metal bolts. Metal fascias. Metal skeletons. Metal bonnets. Full metal jacket. Metal up yours, all the time. That, my friends, is Campfire Audio’s flagship earphone, Jupiter. In October I reviewed a pre-production model. From what I understood at the time, its cable, ear pieces, fit, and sound, were final. The body? By late summer, anyone’s guess was as good as mine.
