Not really sure if this is where I should be responding; apparently some of the thread has been shifted around.   I got some welcome suggestions on my original posts about the measurements of the PM-1 on About.com Stereos. Someone suggested measuring distortion at a lower level, and I'd...

I wanted to respond to some of the comments made here about the About.com Stereos measurements. I think too much has been made of the distortion I found in the Oppo PM-1 at 100 dBA.   I have measured 174 headphones at last count, and with about half of those, I also had some of Sound &...

Hi. I'm the one who wrote the review for soundandvisionmag.com and produced the graph in question. The methodology and equipment I used are spelled out in the review right here. It's all industry-standard equipment, purchased by me personally (at considerable expense, especially for a...

Here's the full quote:   "But you know what? The B652 doesn’t suck. You can find $100 or $200 speakers that aren’t as good. In fact, the B652 is better than some $10,000-per-pair speakers I’ve heard — although those were all really wacky designs built to cater to audiophile fads rather than...

Just a little follow-up. The other points have been well argued back and forth, and I'll leave it for Head-Fi members to make up their own minds.   When we test IEMs, I present the panelists with all of the manufacturer-supplied tips and encourage them to experiment to get the best possible...

Regarding the subjective tests and measurements of the TDK IEMs I wrote for the Sound+Vision website:   As far as the measurements go, I do have a Rane HC 6S amp with a 0.5-ohm output impedance that I could use for the measurements, but I chose the Musical Fidelity V-Can instead because its...

Thanks for the suggestion! Will take that into strong consideration.   BTW, if there are any Head-Fi members in the Los Angeles area who want to participate in our listening panels, please e-mail me at brentbutterworth@yahoo.com.   ---Brent

I wrote the review on the Sound+Vision website and wanted to clarify a couple of things. I didn't say "the HE-400 is like the HE-500." Here are two actual quotes from the review:   "That said, the two headphones do sound substantially different." "The differences between the HE-400 and...
