The juxtaposition of this >kilobuck* thing and TP pleases me.
*Wild guess. Don't stone me.

TP (over tweeters) has been around in studios for a long time. We take a whatever works approach, hence use of Creatology foam, rug liner, etc. For those who wish to pay more, much more, and possibly with more dubious results, we suggest tweaks developed by this renaissance man: http://www.stefanaudioart.com/

Marv will you also be measuring the THD for stock form and updating post #1, just for completion's sake?

Updated first post.

I really thought to pull the trigger for the HE-9 I have on loan and I had some "wow" moments with it but finally I found the slight synthetic tone and the lack of Clarity/transparency stayed a bit problematic with the HD800 and I know I can have better result wit a great tube amp. So I ordered the Stratus . But thus fat it's the best SS amp I heard with the HD800 and the association achieved a really great result. Still not enough for me. I expect more but I'm an asshole when I'm after the "right" sound for my ears. not heard the Rag though. the Schiit Unit is on my radar for when I'll build a speaker + headphone rig.

You might consider the Liquid Crimson. It's really great with a similar FR to the M9, but more resolving and more involving.

I thought to that after Marv's review But I've decided to go to the DNA Stratus.

You've got a PM

Wow, you are making the M9 sound like a not good amp. Maybe very clear sounding, but flat and boring. Don't they call that wire-with-gain-and-feedback?

Dunno for the M9 but the HE-9 is not flat , nor boring or uninvolving , at least with my HD800. Great Bass and soundstage, a lot of smooth power but clean , grain free. A notch on the warm side. my 2 cents. sounds like a big V8 , smooth (onctueux) with a lot of Torque but able to kick you ass if needed. (how do you guys say "souplesse moteur" in english ? ) . Like a big 1400cc 4 cylinders in a motorcycle. smooth, powerful but never brutal. opposite of a 2 Strokes GP500

ahhh nice! posted my query in the 'he-1k stream of consciousness' thread prior to finding this, but this seems like the right place for my query.

I was having a bit of measurement difficulties with the he-1k. seems quite sensitive to positioning & difficult for me to get precise readings after multiple trials. also curious what is the amplifier used in the measurements posted as I had some concerns about the whether my Oppo HA-2 is adequate for measuring the FR on the HE-1k.

Looking at purrin's measurements, it is actually more relieving. I did get some similar results in the overall shape of the curve with the jaggedness throughout the midrange & the upper treble recession, but I was afraid that my results were due to measurement artifacts. my csd plot was totally weird as well, but it is good to read about the presence of the ortho wall.

sry for the cross-post, but I appreciate any other additional feedback or assistance for a relative amateur trying to get accurate measurements on the he-1k! thanks!!

cheers

It's actually not that surprising: I already preferred the SA-31 to the built in amp in my ex NFB-27, which was basically a Master-5/6/8. Granted, the M9 is slightly different than the 5/6/8 (a bit warmer and better technically) but it didn't really move me. I kept the Rag when I owned both because of its warmer and more inviting midrange (like the SA-31).
Reports say the HE-9 is a better animal than the M9 as well, and tuned a bit warmer still. Might be closer to my preference, especially with the HE1k.
The Crimson is my favorite amp of the bunch, by a good margin.

Sorry for the OT.

I use an Objective 2 amp for measuring since it has excellent measurements but sounds OK/mediocre/actually-kinda-bad. Measurements are measurements. Really won't matter what amp you use unless you do some really odd impedance mismatch.

Inconsistent measurements in the high treble are expected, but other regions should be consistent, especially with planars. Some jagginess in the mids with this headphone and some other planars is normal. Are you getting a good seal? Hard for me to say unless you are more specific about your measurement rig, the parameters for CSDs (window, rise time, etc.)

hey purr1n,

thank you for your advice & feedback. I will look into that advice thread you linked. I accidentally ended up cross posting, so here is my measurement chain again: Dell XPS m1530 with Windows 7 > ARTA Generates Sine Sweeps > Steinberg UR-22 USB Interface with Yamaha ASIO > Line Out > Oppo HA-2 Amplifier > headphones placed upon my own head (left ear being measured) > Pannasonic WM61-A Microphone > Steinberg UR-22 > Laptop > ARTA analysis.

I will look into the parameters for my csd plots again over this weekend. I appreciate you taking the time to respond!
