Ultrasone Pro 900 Impressions Thread - Page 30

post #436 of 5883

Speaking of amps for the Pro 900s, I just bought a second-hand Lisa III w/power unit.... This will be used in a stationary manner at work. I am looking forward to hearing how it pairs up with these amazing phones.

Changed the title.  This is now officially the Ultrasone Pro 900 Appreciation Thread.  Thank you to all those who have contributed and shared how much you've enjoyed these headphones.  L3000.gif

Great job Jibbie...

 

How did you change the title?  Last time I changed a thread title was back with the old site where it had an "advanced" button.  Maybe I'm missing something in the full page editor.

 

And to keep it on topic...I love my PRO900s....beerchug.gif

Haha glad to hear it!  Right underneath the title it says "change title" in parentheses.

Haven't posted a while in this thread, but was the KICAS Caliente ever discussed with the Pro 900s? Because I can vouch that this combo delivers some amazing bass - deep and punchy.

The main problem with Usone 900's, that I noticed the other day at work, is you can hear the instrumentalist breathing :-)

Thanks for the renaming of the thread!smily_headphones1.gif I hope to join in the club sometime, hopefully within a month or two. All the old threads on the Pro 900 are pretty OT or give weird impressions, no offense to anyone. This thread seems to give much better perspective, and is helpful.

 

I hope there is some more discussion on the various cables available, as well. So for so good. I want to put some good silver or nice copper on these balanced, eventually.

I'm appreciating the sound I get now out of the Matrix M-Stage amp compared to my old portable Practical Devices XM4 w AD8620 opamp, the sound is fuller and more engaging and has a certain sparkle to it, though I was hoping for more bass. I'm a little annoyed now that with significant burn in (close to 200 hrs) the Pro 900's bass is now tamed and less rumble-y. During the mid stages of burn in is when I preferred the bass the most I think, it had a little more presence to it compared to now which kind of sucks for me. I listened to New Blood by Hospital Records as Jibbie suggested (Royalston - The Test is pretty sick) and while definitely a solid drum n bass album, I found myself yearning for the bass solidarity the cans exhibited before.. Cyrus - From the Shadows is a good album to see what your headphones can do basswise as well (listen to the track Dirt), that stuff is just pure bass

In fact, I'm quite satisfied with my E7. I was just wondering whether it is a good idea to "upgrade" to a bit more expensive and possibly better amp/dac like ibasso D4,  even though volume-wise, I've never had problem even with Cowon J3 and Fiio E7.  Given the same level of volume, if the SQ improvement between D4 and Fiio E7 is just marginal, then I would definitely not go for any other amp/dac. :) I'm afraid once I get into the world of "decent amps/dacs", there would be Money problem but also relationship problem! My gf uttered "No more headphones...."very_evil_smiley.gif.....

 

I have not tried ibasso dac/amp so I can't say for sure but I highly doubt you will hear the difference, unless you have super sensitive ears. But most importantly, when your gf says no more, I would heed that warning if you want to enjoy listening to your phones in peace.


Tell her no more pocket books or shoes.

If you want more bass, you can try what I did. If you open up the cups you'll see there is a white sticker covering 2/4 of the bass holes. Removing that to open the 2 remaining holes should increase the bass.

Give this track a try to test the bass.

So should I unscrew everything first? When I remove the pads there are three triangular holes covered with white felt and two larger plastic black circles. Do you notice a discernable increase in bass?

Unscrew the 4 outer screws, not the 3 in a triangular arrangement that keep the driver attached. Then you should see a white semi-circle on the back of the driver as pictured below. Removing this will allow the driver to push more air. Someone recommending only uncovering 3 as they had issues with all 4 uncovered, but I've had all 4 uncovered for some time now and not noticed any problems. Make sure you use a precision screw driver kit as I have found that my screws are becoming rounded which is not good!

 

It's hard to say how much of a difference it made as its not something that is quickly reversible for fast comparisons, but I'm not planning to tape the holes up again as I'm happy with the bass now. Would be interesting to have 2 pairs of Pro900s for comparison, one with this mod and one without.

 

I still think the XB700 is bassier, but the overall sound quality of the Pro900 exceeds it.

Here are some tracks I like to show off the bass:

 

Breakage - Higher

Breakage - Justified (actually anything by Breakage :p)

Break - Time After Time

Suspicious Stench - Ghost Town

Digital Mystikz - Eyez

Loefah - Bombay Squad

Photek - UFO

Cool thanks for the info, I'll try this once I get hold of a precision screwdriver

post #450 of 5883

I am very interested in knowing the outcomes. Please post your impression after the mod!
