Usage would be 60% with DT880/250 and 40% with CK10/SE535/Clip-ons. Thanks.

I have a pair of DT880s coming on wednesday and I'll be sure to post some impressions with both toslink and usb

Sounds good. Also, if you can indicate which DT880 model (32, 250 or 600 ohm) you'll be testing, that would be helpful. Be sure to burn-in those drivers before posting as they can be quite piercing out of the box.

250 ohm, I wanted to get the 600 ohms but would afraid from the specs it wouldnt be the best idea. I'm curious to hear impressions of the 600 ohm DT880s with the MK-II. How long do you think I should burn them in, I usually just burn in like 24 hours

I can't recall how long it took before they were listenable, but it was longer than 24 hours...maybe 100. Almost wanted to return them when I first got them. Just had them simmer on the amp for a few days and the sibilance was tamed.

Which Op Amp? 209ID? I never found 8610 to be sibilant. Maybe a tad rough around the edges before burn in though.

My point is where you using them out of the UHA6MKII and with what Op Amp when you found them to be sibilant? ;)

Well my op amps finally came in today......no way in heck they'll ever fit in my Leckerton. Looks like I'm going to have to chat up a friend and see if he can maybe solder them onto a mounting board like the op amps I got from Leckerton.

I used the DT880 in my Compass, PC soundcard, etc.

yep, no biggie though. I think I can get Armaegis to maybe solder the op amps onto boards. If not I'll just try them out on my Marilyn amp.

Ok so I gave them a little test run and on high gain I can crank the volume to max without it being too uncomfortable but there is no headroom for me to the point where its too loud for me, but its loud for sure. Just wanted to post this quick, I have them burning in so I'll post more in a few days.

Is this volume position with the DT880/250?

Nick is going to ship my amp soon enough.

Can't wait till after new year to get them ^^ (together with the mad dogs)
