Roy (Romaz, on the boards) arrived for a visit to Big Sound 2015 today. He crushed the blind test, and went on to a very detailed evaluation of the headphones and amps present.

This one is not to be missed.

Oh happy days! Today I performed a long awaited experiment of creating an EQ for two pairs of headphones from my understanding of the raw frequency response measurements and the Harman target response curve. The acid test was whether or not Bob Katz felt the EQ good while listening to tracks he's intimately familiar with.

Read on to see what he said....

Day one with Bob focussed on the normal routine of blind testing and evaluating the cans. We set out sites high on the blind test...and didn't fair well.

Crossing the country on a quest for further training in fine watch repair, Jonathan found his schedule line up with Big Sound 2015. He really enjoyed the layover.

It was with great trepidation and joy I awoke this morning in anticipation of the first official Big Sound participant. Three weeks sick certainly set me off my pace, but I'm feeling pretty darned good now, and I'm so thrilled to be starting the project in ernest now.

What would the day bring?

WARNNG: This is not headphone science. This is just a very, very complicated headphone anecdote.

I couldn't make it, but Mike (Anaxilus) did and has submitted this ShiitShow report...which, if I may say, is simply an outstanding offering.

Something had to give: Tyll has given me the assignment of evaluating a bunch of midprice phones. But I feel that the amps I have to drive them are not completely up to the task. The Burson Soloist is fun, punchy and “tubey”. The O2 sounds comparatively transparent and is a great bargain, but how would it compare to the big guys? So I knew I needed to include a transparent high class amp to drive and test these phones. But Mary would divorce me if I proposed buying yet another expensive headphone amp. Instead I found a solution: Build one instead. The process has proved to be very rewarding in all respects. Let me tell you about it here.

Readers may have noticed that Editor Tyll Hertsens has not been posting for a while. Turns out he suffered a burst diverticula of the intestine which lead to a bacterial infection of his liver. Those who know what this is are probably wincing about now. For those that don't, it's serious, but luckily treatable, and Tyll is recovering at Bozeman Deaconess Hospital (pictured above).

Update: Tyll is now home!

Tyll is in good spirits and hopes to get released later this week. He also expects to pick up where he left off with Big Sound 2015 and says he is getting ready to start working on posts again. We're suggesting he take all the time he needs to rest.

Let's all wish him well, and hope he is able to go home soon!
