post #21211 of 23373

Is the t 20 a different driver?
 

post #21212 of 23373

Not that I've been able to tell...

post #21213 of 23373

Hmmm. Curiouser and curiouser, wonder why no mad dog T20 mods then?  This may require me dealing off some Senni's to fund a T20 experiment. Time to cruise the Thievesbay methinks.

The T40 is fully closed. The T20/50rp are semi-open.


 

I know that some people in here have achieved seriously good results with modding the new T20 ,almost , if not completely indistinguishable from the modded T50 results .

They can check in here I'm not going to put them on the spot, or you can ask in the T50 Incremental Mods thread about that bigsmile_face.gif

First picture. HP-50 + HOK pads on top of the stock pads, i.e. with two pairs of pads for increased distance to the ear. Measures well even then (3 kHz ridge is mainly a measurement artifact).

 

Second picture. Same as the first, but this time a wool disc was placed inside the cup, between the driver and baffle where the white stock disc would go, rather than on the outside of the baffle as in the first.

 

With the wool disc inside (again, between the driver and baffle, not behind the driver) rather than outside, the sound is faster to my ear, and also measures slightly faster in the mids. Why this is so, I don't know. Could be the extra treble as well, but probably not entirely. To restate, when I had the disc inside on one channel and outside on the other, the inside one sounded faster.

 

Also, with the wool inside rather than outside, the soundstage seems wider. Could just be random shiftings of the brain, but might not.

Because the T50 is the most expensive, and thus the "best".

Yeah, more money the better:) I fall firmly into the skeptic category, particularly with audio these days. There are some spectacular products out there that never get their due just because they are not stratospherically priced and hence are ignored by "audiophiles"

 

 Think I'll follow up on Nick N's post up there and perhaps take a crack at a pair of T 20's (unless dirt cheap YH's or something get to me first)

ask in here for sure, I betcha you'll get some reassurance.

The idea being to compare at which point (50, 40, or 30 Hz) the response seems to start drooping in volume compared to the volume at 1 kHz.


I finally got a change to test the ECR-500.  I also used the tones on this site http://www.audiocheck.net/testtones_sinebursts20-200.php because I wanted to test 20Hz as well.  Those tones seem more accurate than others I found.  They seem to match the tones you posted were others were much louder.  The dip starts around 50Hz.  30Hz is still audible and the level goes up at 20Hz to approximately the same level as 40Hz.

post #21223 of 23373

Thanks. Seems that the ECR does well for itself as well. Curious that they have a hump below 30 Hz...

post #21224 of 23373

That surprised me too.  That's the first headphone I heard that.

In reply to my statement on the Fostex and the Hifiman, holy crap give a look at the Yamaha hp2 holy cow these things sound good. I didn't think something this old could sound so damn good..... Wow I'm blown away, honestly. I just got them in today, while they lack the subwooferish bass of the Hifiman everything else about the hp2 is simply amazing except they do need quite a bit more power to drive.
Just another reason why I won't touch anything but yamaha speakers when it comes to speakers.

Correction the Yamaha HP2 can pump out subwooferish bass, I just ran lil Wayne King Kong through them..... Damn I'm really impressed.
