I have the HD 380 Pro and the Beyerdynamic Dt 770 Pro 80 Ohm, and I find the DT 770's are superior in build quality and sound.  You might consider Beyerdynamic Custom One Plus, which are pretty much a DT 770 32 Ohm with detachable cable.

Right now on amazon.ca they are both listed for the same price of $199.99 CAD.  Makes one wonder why didn't Sennheiser release the 598Cs as the HD 569 and a year from now release the HD 599 SE and the HD 599 Cs?

The images for the HD 569 and the HD 598 Cs show they are different.  The headband for the HD 598 Cs looks exactly the same as the HD 599!

I am looking to buy a better pair of over ear headphones than the HD380 Pro (which I have owned for a year & a half now) on Black Friday 2016.  I have the matrix m-stage dac & the matrix m-stage hpa.  I listen mostly to rock, blues, r&b, jazz, and edm.  A fair amount of my collection includes...

TY for sharing this info.  However, I do have a question...  What is the difference between the one your link shows on soic & another that is listed on dip?   http://www.ebay.ca/itm/2-pcs-LME49710HA-Adaptor-/171079253279?   Oh, also do you know if I need SAE or Metric Allen Key to remove the...

THANK YOU!   Nice to see I was not the only new member who did not know this! 

Hello, New member, long time lover of music, who has been lurking for a couple months after viewing some youtube vids by Hifiguy528 & also by Jude. When quoting someone else's post(s), how do you make it say "Originally Posted By" ? Just want to make certain credit is given where credit is due!

  Thank you for letting me know that I definitely should not get the OPA637BP.  Seeing it was the most expensive of them all, I was figuring it to be the better option.   hmmm... I need to figure out how to properly add the quote...  ;(

I just purchased the Matrix M-Stage DAC, having purchased the Matrix M-Stage AMP last month and am now considering upgrading the opamp.  I have found a few listings for the OPA627AP/BP & OPA637BP having the biasing mod.  I also spotted the LM4562 as is or on a dip adaptor.  If I go with the...
