Grasp the connector as close to the HP as possible and gently work them back and forth. They should pull out after a couple of seconds.

Interesting.  I'll have to compare again, but I still think the JJ's were at least more transparent than the GE 6BZ7.  Back when I had a Bellari tube phono pre, I used three tubes: Mullard 12AX7, Electro Harmonix 12AX7, and JJ Tesla 12AX7.  The Electro Harmonix was the most "tubey" sounding (least transparent).  The Mullard was in between, and the JJ was the least "tubey" sounding, and most transparent.  I'd imagine that most new-production JJs follow that same sound signature, although I'm not claiming that the JJs are world-class by any means.

We are both correct in this case. The E9 has plenty of power to drive the HD650, but the O2 is just a cleaner, better sounding amp. It will be more expensive however, unless you assemble it yourself from the bare circuit board. I own the O2  and can attest to its quality.

 

I also own the HD595 and previously the HD650. The HD650 is quite a superior headphone, but it has a different type of sound signature. With an O2 powering them (probably even an E9), their technical superiority should be fairly obvious.

I definitely appreciate mine.  These are the only phones that don't hurt my ears on loud volume.

E9 is a fantastic match for the HD650, I even preferred it over the much more expensive Burson 160.

It makes sense to me why some would prefer the HD-650 on the Fiio E9. I have one and rarely use it, but it seems quite neutral.

If I were to get another amp for the HD-650, i'd prefer it to be as completely uncolored as possible. Like dead neutral or close.

Is the E9 close to being as neutral as the O2? My guess is that the E9 might give one the impression of a little more treble than the O2.

If anything, the E9 seems to do something strange with all my headphones. Seems to magically give them a much larger soundstage. Pretty bizarre. Even my DJ100 and KRKs!

 

I actually remember liking the E9 over the Asgard for the HD-650. Maybe it's just that it's more neutral? Who knows. I did however prefer the HD-600 on the Asgard over the E9.

 

I've been wanting to try the HD-650 again, but I think my Micro Amp +HRT MS II would be a horrible match for it. The Micro Amp by itself is perfect. I'm kind of on the fence again about my HRT. Seems kind of too warm (for me), but probably my imagination.

 

I wonder why the HD-650 always seems to measure flat as a pancake. Never sounded that way to me on any amp. Not like it matters.

Have you tried the HD650 with an amp that isn't op-amp based? Or with a decent regulated PSU.

What did you prefer with the E9 that the Burson couldn't provide? Just curious as the HD650s sound excellent on my HA-160DS but fairly sterile sounding on a Pico DAC/amp fed with ALAC files.

Thanks for the tips. It worked and after the first time it's easier to do it again. Did I accidentally break something ?wink.gif

If you plug the wires back and they sound glorious, then no.....biggrin.gif

It's definitely plausible.  I preferred E11 with HD650 to the much  more expensive (old) Headroom Micro.  The mids weren't congested on the E11, they were with the Micro.  Not a bad amp, just not a good pairing for HD650. 

 

I prefer Lyr vastly more to both however.

Yep, rolled off treble really helps if you have treble fatigue!

Yesterday I compared the HD650 with the HD800 again.

 

Some times ago the HD650 was my favorite headphone, today I don't like it anymore.

 

Compared with the HD800 it loses from the bottom end up to the highest highs.

Even the wearing comfort feels a little bit better on the HD800.

 

But the end of the story is, that I'm still not able to sell the HD650... and I don't know why.

 

Maybe it's the same secret reason out of my subconscious, why I've also kept my HD600 and before that my HD545, and many many other cans...

For me the two each have their own sonic signature. So far (maybe because it is what I am used to) I prefer the 650's over the 800's. Perhaps more time with the 800's would change my mind. The point is I am certainly happy with the 650's and do not consider them to be a compromise vs the 800's. As always, YMMV...

UPS took long enough, but I finally got my HD650's today. Since this is my first foot into the audiophile world, I have a few questions. They sound pretty good fresh out of the box, and plugged into my Sony home theater in box. So I'm just trying to imagine how much better they sound when they are properly amped and DAC'd. Does sound quality greatly improve with the amp or is that mainly in the DAC? I'm still trying to decide on an amp/DAC, but I'm leaning towards the ASUS Xonar Essence STX since I'll use them 99.9% of the time at home. I was going to go Fiio e17, but I keep reading about a huge improvement in sound between the e17 and the Essence STX, and for $40 more it seems like a no brainer.

 

So I guess I'm looking for some pointers on that decision. Would the STX be a decent place to start? Also, what is the preferred method of burn in? I was just going to plug them in and put Itunes on shuffle.
