Hi, I rested the microphone of an LG cell phone in one of the ear cups and used the Android 'Sound Meter' app. After finding a comfortable music volume on the uDac, I nestled the phone in the ear cup, played pink noise, measured the dB value, plugged the headphones into the Magni without...

Thanks very much! It was really fun, took about an hour and afterwards we had beers. If anyone wants to try their own test I'd be happy to help with the stats and methodology. The more objective data the better.

People have been arguing about amps for a while, whether they all sound the same so long as they don't suck and add distortion (a 'wire with gain') or if better designed, more powerful amps really do sound better. With the help of a friend, I ran blind tests of three different headphone...

Thread revival! Thanks mate, these details helped solve my cable problem, which was to attach the headphone connectors for HE-500 to a set of balanced cables from an old HE-4XX. :beerchug:

Hey mate, if you still want to run an blind test (have someone else choose a source by flipping a coin, you judge source a or b or same/different), post your results and I'll run the stats for you.

Dragon Lady by The Geraldine fibbers with Nels Cline from Wilco on guitar and Carla Bozulich on vocals *swoons* To really enjoy it, synch up this file with the video, unfortunately music video is edited when she starts cursing so you'll have to pause the video for a few seconds ~2:10 to re-synch...

English, Spanish & French.

♩ Thoose were the daays ♪. I also miss UncleErik and even grumpy BlackbeardBen. And of course he-who-must-not-be-named. I remember people turning in blind test result and running stats on the data. Emperors were shown to have no clothes, measurements ruled, innovative, superior amp designs...

People swear by that HD650 & Joti combination. Do you even like the K7XX more than the HD650 with that same crazy powerful amp? Does the K7XX ever get too bright given the amp's signature? That would be quite the bargain (minus the amp of course)

Yes, a direct comparison to HE-4XX would be ideal, thanks! HD600 have a very natural treble, that seems like a great comparison. I am very much enjoying my new HE-4XX but have started hearing odd things like that in the treble and just want to make sure HE-500 doesn't have that so I can...

I have a question for HE-500 owners. During the Maggot Brain guitar solo by Funkadelic, you can hear when Eddie Hazel turns up the distortion/noise floor on his guitar and a high-pitched hiss becomes audible (4:21, you can also hear it when things go quiet 4:57). On HE-4XX this sounds like a...

Doing some critical listening of some new headphones (but usually getting lost in the music) with Maggot Brain. This track in particular can sound like heaven with the right headphone.

To find the relation between amp watts, headphone resistance and amp voltage, Ohm's law will determine any one factor from the other two. i.e to first calculate voltage out an amp from its listed X mW@Y Ohm spec for some given ohm, then plug in that voltage to compute the mW rating of the amp...

One detail is that my headphones all have pretty low impedance (30-60 ohm for LCD-2, HE-500, RS-1), so an ideal headphone jack would need to have some watts to maintain current over a low resistance. But maybe that's not too important because I only listen at lowish volumes. More important I...

I'm reviving this old thread because this question is still relevant, maybe even more now because stereo receivers now have digital inputs, decent dacs inside, chromecast capability etc and I haven't found many good answers to this question. Does anybody know if there are modernish integrated...
