If you mix audible and inaudible (ultrasonic) content, you might get IMD at some element of the audio chain. For example 20kHz sine wave + 1kHz could create a distortion at 5kHz making recording sound harsh, even though originally it didn't sound like this. Of course it's highly improbable, but I wanted to show, that not always more = better. I think there is no reason to record something we can't hear.

Planar magnetics like the HE560 have very low intermodulation distortion.

How do CDs rate out of a good dac and amp

Please, don't discuss format differences here, it is OT and meant for sound science!

But how I would like to add my own personal rant, lol..!
I'll happily answer pm's, though wink.gif

Not true, ambient information is just one example outside of known/measurable human hearing.

ABX tested?  Conversion from lossless to lossy and volume matched? 

 

 

How do the cables effect the sound?  I'm debating on buying a cheap silver ebay cable :p 

I think the stock cable is very good. What I am using still needs to burn in. I would not buy cheap silver cable though, unless upfront, you know it is very good as silver not done right can sound cold and edgy.

Seems you are confusing stuff here. Search IMD if interested.
Or are you implying ultrasonic content can be heard/sensed?

Certainly interested if the money is worth it over the 400i.

Fostex bought the cover commercial of the brochure and spread the image of their new planar TH-500RP to any places you can see; HiFiMAN had their show stands printed with the images of HE560 and HE-400i and attracted everyone's eyes; OPPO paired their PM-1 with their headphone amplifier/DAC and BD/SACD player, looked as fancy as you can imagine.

Now let's talk about the sound: In my opinion, the least impressive is OPPO PM-1, although the industry design is top notch. PM-1 has a "thick" sound signature. I feel that the mids is sometimes over saturated. the bass is full and bold but not well defined. The weakest part of PM-1 is in the highs. I picked a SACD "Die Fledermaus" conducted by Carlos Kleiber, and I was suprised that the sound is so muddy, the brilliance of the strings on the Wiener Phihlarmoniker totally disappeared. It's just like you are listening to an old LP instead of a well transferred SACD. After the end of the overture, I switched to another Japanese popular album. The female voice sounded smooth, but not well focused. Another drawback is the soundstage. It just feels like that PM-1 didn't catch any magic all other planar headphones are able to produce. 

HE-560 of HiFiMAN on the other hand is the total opposite. The industry design is still no match with the top dogs, but the sound is simply terrific. I think this is the widest and deepest sound stage you can find on a planar headphone. The sound is very sophisticated just like the velvet. You can feel the air arounds every instruments and the singer, even the smallest noise made by the members of the orchestra when they touching the score can be revealed. The bass is not as deep as a properly-driven HE-6 (what is?). it sounds slightly softer, but still goes plenty deep, tons of details and never interfere the mids. The highs is very impressive, it's so airy and never let you feel uncomfortable. The most important is, the HE-560 is so life-like and musical, the illusion of a famous singer standing before you appears every time you wear the headphone and close your eyes. One STAX addicted guy sitting beside me told the staff on the booth that the sound of HE-560 surpasses 007 and only beaten by 009.

The Fostex TH-500RP sounds "pretty", that means it features a traditional Japanese sound. The highs is very transparent(but sometimes slightly brighter than i like), the mids is a little pale and the bass is quick. It's hard to say I like it or not, sometimes I think this is too artificial, but the beauty of the sound is still attractive. I've been told that the demo on the booth is the "final prototype", so maybe there will be some slight change on the official releasing.


HOLY balls. The part about the STAX guy... Yup so, time to buy these (not just because of this, but what else I've read). I feel you need to hear other planars to make that previous statement though. From your profile looks like just HiFiMan cans.

They're the first planars I've personally heard that's gotten the treble right.  (HE-400, LCD-2, LCD-XC, LCD-X, PM-1, Mad Dog 3.2)

post #4376 of 8211

After letting my 560s run for a couple of days, the treble stridency has receded to a more comfortable level. I'm hoping it will tame just a wee touch more, to suit my personal tastes. Using it with a Lyr (stock GE tubes). 

 

I tried switching the ear pads with the rev1. Treble does soften a bit more.

 

Right now, it looks like I'll be shipping my rev1s back, but I'll give it a few more days before I decide. I might see if I can arrange to keep both pads. It would be nice to have that option in the future.

Did you have the 5le or he4 as well?

Quite impressive. I honestly wanna see if the 560 is worth the money over the 400i.

post #4379 of 8211

Have not heard either of those two.  Based on ears I trust, seems like the HE-4 doesn't get the treble right either. 

post #4380 of 8211

Yes. HE-560 does a good job on treble. Audeze's being too rolled. PM-1... whatever. HE-4 or HE5 most certainly does not get the treble right. HE5LE, a little better, almost. HE-500 does good tho with minor quibble in mid-treble. Taking measurements of HE-560 with the original pre-production pads to confirm warmer sound. I suspect the HE-560 with the pp pads are probably the best combo. At least for me.
