French Doctor :-)    If my guess is correct, I think the ETHER C will sound fantastic with a Viva amp.    Je veux acheter un ETHER C bien que je n'ai pas l'argent.   " or " bien que je n'en ai pas les moyens.   I wish i could type english sentences as well .. 

So,   After multi test phase with Green, Red and Yellow TB Tubing, Yellow is the winner for me. It does not change the sound much.. and if it does, it's in a nice "deep" way.. Talking about the sound stage, The Tubing enhance it a little bit... so you may check this out for 4€45 on Ebay port...

Another interesting view... they seem to have about the same diameter on this pic... and it's not filled up...

  To make up your mind about size increment... I think i'm going to pick a piece of Yellow, Red and Green, to experiment properly.. Though, i did a test with some 4 mm electric cable and it did affect the sound in a boomy way..

Hahaha...   :-) Excellent ! I'll be digging around ..   Cheers 

Excellent idea..! you've got gut to ask :-) well done Green would me perfect to me.. Jackson1, I guess you've just ordered the green / Heavy / dispenser  ..?   That would be awesome... :)

^  WOW.....

That's not the result i get with the 7520s, A thin mix. As i stated and discussed before, here and on other forums such as gearsluts yep, you need to monitor at very low level for mixing or mastering duties. The extra sub region is fast and tight; for electronic music producers, it's a must...

Haha :-)

Sonarworks indeed

@ Dakanao   Closed back Hps VS Open ones... So can't really compare.... But They both are a bit on the dark side (sound sig..) Kind of flat HPs, lack of sub-basses on both, a little bit of muddyness on both, but the openness of HD650s compensate that..? The comfort of the Sen's is...

I you like claustrophobic HPs.. go Focal.. and i'm french...

7520s :-) more air, more details, less claustro...! I own both.

Hey,   I completly agree with Rude Wolf, plus I feel the 7520s are tough ones to calibrate. I own HD650 and FSPros, and i can "Wet" the signal to 100%( 100% correction ), with a very very good result. ( OUPS... FSP's not on the list yet.. ;-) But i like the 7520s better..! in every...

Cool, i actually own two pairs of 7520s, and they are really really close.. in term of sound signature.. so, i'm sure you'll get 95% of the "cure" :-)

Waiting for the response... I'll report back as soos as..

Hey jackson1,   I thought about sharing my calibration file you guys... But i'm not shure Sonarworks would agree..  I'll have to ask if they are ok with this... the calib file is taged with my name..

Just wanna share this... My 7520s mesured by Sonaworks.. ( i have sent them to Riga - Latvia ) I'm fiding myself dialing the mix knob to 67% Wet, to get the ideal flat balanced sound i'm looking for...while listening to favorite "Reference" Tracks, for mastering and mixing duties.. Doing...

For me they came straight from LA to Paris for 17$... shiping included.. 4-5 days max...!  I did this 3 times, it flies in a slim envelop so... it's quick safe ans easy.

The V-Moda straight cable will do the job in an awesome way.. Plus you'll never feel it... it's so light     http://v-moda.com/audio-only-cable/

I completely agree. I am able to hear some sibilances on the 7520's I couldn't detect on my Focal Cms50 Monitors BUT hear again on my macbook pro HP's... 

Oups sorry, i was talking about 50 Mega Octets ... No 50 Minutes :-) Anyway, I'll have to try them both for myself..  Have a nice WE ;-)

Thanks that would be great :-) could you handle 50 Mo ? For 5 songs ? The Two firsts are 2 Dave Pensado's References songs to check Bass guitar and overall mix balance. Plus few "groove" tracks that i know pretty well - old house music -progressive edm -Funk house music   Thanks :-)

Hi Int,   Great :-)   Could you tell me more about the sound signature on some electronic music..? House, Hip Hop, anything with some serious dynamics and great impact.. no no, no Dubstep.. ( joke ) Which one "would" be the most painful for extended listening.. What's the main difference...

ok, after some more readings on Gearslutz, i lean towards FSP..
