Bob Katz fills us in on his Big Sound 2015 experience.

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.

Hooo boy! Bob pulls out all the stops in his latest episode.

This is a little treasure trove of incisive opinion on a bunch of pretty darn good $150-$500 full-size sealed headphones.

Bob Katz has fallen in love with the Oppo PM-3 and HA-2. A rather long review, but hey, he's in love. Waxing prosaic is part of the deal.

After those episodes, conspiracy theories have abounded: Did somehow my brainwaves have managed to influence five strong-minded individuals in my direction. Was it valid for Bob to use different amplifiers for the two headphones? And why did Bob and Tyll's findings on the Utopia and LCD-4 differ so much?

Let's find out!

Today I'd like to discuss what I mean by sonic perfection or sonic neutrality. Most audiophiles have observed that excellent playback systems of different manufacturers can sound radically different! Even the most accurate loudspeakers are subtly voiced and are different sounding. But how can there be more than one "right"? Philosophically speaking, two different-sounding playback systems can't both be "right": one of them must be correct and the other must be incorrect! Or maybe both are wrong!

I have a love affair with my Stax SR-007 Mk2 phones, which I judge to be superior, smoother, more musical and accurate than the expensive SR-009 model. What's with Stax? For them "better" seems to mean brighter, but why manufacture an even brighter headphone when the 007 model already sounds too bright? Stax seems to be obsessed with detail at the expense of musicality or even accuracy. But after-market amplifiers have sweetened that tune to a great extent.

These specifications confuse consumers, who would be forced to use logarithms and equations to answer the basic questions. We need to make headphone sensitivity and amplifier level specs more user-friendly, useable, interchangeable and effective. So I think it's high time to ditch both sensitivity approaches, and we can do better than both Sennheiser and the IEC if we start thinking outside the box!
