Sennheiser HD650 Impressions Thread - Page 292

post #4366 of 36844

I understand how more treble can give the appearance of more detail, but what's still interesting is how a bass beat on the SRH-940 seems considerably more controlled and detailed (even when I EQ highs down to 0) - it sounds more like it should (not muddied at all) as opposed to the 650's. The 650's have really good bass of course, but listening to the SRH-940's for the same clip reveals so much more resolution in the bass - this is what confuses me. If it's not because my amp is lacking for my 650, then I'm not sure what to make of this. Sorry if I'm spamming here with posts about other headphones, I just wanted to make sure I wasn't doing something wrong driving my HD 650.

I didn't want this to be true at first because my 650 is so much more comfortable, but I can't deny what I'm hearing.

 

My question is, could it be that my HD 650 is improperly amped? I've heard that without proper amplification the HD 650 sounds a bit more muddy and veiled. And, if so, what amp(s) would you recommend that are known to be excellent with the HD 650?

Interesting findings.

 

It's unclear what amp and DAC you're using, how much you're EQing and which headphones you're EQing?

 

Maybe we could start with your current rig and what/how you use it  (gaming, CD player, computer HD music, portable player?

I'm using the DAC/Amp in my sig, Audio-gd NFB-12 (my one and only DAC/Amp). These headphones I EQ'ed are Shure SRH-940's. I used a software equalizer. I'm gonna try to test with a better software equalizer later today when I get home, but it seems pretty clear that the tight bass I'm hearing has nothing to do with the highs (I mean you can tell that with your own ears, but it's good to be objective).

post #4369 of 36844

Are the 940s reaching lower than the HD650s?  Sure the HD650 bass emphasis does to tend bleed some, but if the 940s are reaching lower AND are tighter then that's very impressive.  

post #4370 of 36844

I know, I was startled to say the least. I'm gonna do some more listening when I get home on my DAC, but one of the first things that struck me listening to the 940's was how deeper and tighter the bass seemed. It's definitely tighter with what I've tested, but I should do a careful frequency range comparison to see if it actually extends lower. It sure sounds like it though in music and movies, etc.

Ok I tested more thoroughly. The 650 has slightly more bass and extends very slightly farther I think, as expected I guess. However my observation of the 940 bass being tighter and just clearer in general is confirmed as far as I can tell. I EQed the 940s to be even more laid back than the 650's and the bass detail was still clearly superior. If I turn the volume up to unbearable levels on the 650, the bass tightens up, but still not quite to the 940's level at moderate volume.

 

I find this kind of interesting though:

 

graphCompare.php?graphType=0&graphID[]=860

 

That region where the HD650 impedance jumps to 500 ohms is pretty much the exact frequency range I'm talking about where it's not as tight without turning the volume up to unbearable levels.

IMO the HD650 really comes into its own when paired with a powerful amp like the Lyr. I continue to love these phones and see no reason to upgrade to the LCD-2 for example. I would enjoy auditioning the LCD-2 and HD800 on my system. The SRH-940 looks like it is easier to drive based on its specs.

Yup, with good amplification, the HD 650 may even be preferable to some over the HD 800 due to the sound signature.

 

post #4374 of 36844

AC500, that would be in issue with improper amping, could easily cause a pretty large drop in power delivered if the amplifier section of whatever you're using doesn't have the voltage to cover it. However, it's not really a big deal if you're covering all your bases equipment-wise.

Well I have an Audio-gd NFB-12, which I've heard is a pretty good DAC, but not an incredibly powerful Amp though. Still, this is kind of disappointing because it seems so wasteful to upgrade to a $1000 amp.

post #4376 of 36844

That would imply that the lower frequencies on their own are harder to drive than the rest of the spectrum (right?)

 

I've never heard anyone report bass being tighter and more refined on HD650s after they switched to the Lyr.

 

Jon? 

post #4377 of 36844

Louder volume = tighter bass makes no sense. . . 

 

EQ them to be less boomy, pair with a SS amp. 

post #4378 of 36844

My HD650's are for sale in the classified section. $285 shipped within the Continental US. Best price i've seen online is $340 plus shipping. These are practically brand new, not a mark on them and already broken in.

 

Can do a bundle deal along with the HeadRoom amp as well if anybody wants the set. 

post #4379 of 36844

I don't know then, maybe part of what I'm hearing is due to the emphasized deep bass smothering a little but of the other tones, in which case turning up the volume would allow me to hear the upper tones some more. The point is I definitely hear more detail in the bass of the SRH940.

 

Anyway... I still like my 650's, even in addition to their comfort. For movies and some songs with harsh treble, the 940s can be harsh on my ears. The HD 650 always sounds good with anything, it seems - especially nice just for relaxing movies or something where I'm not interested in listening critically.

I don't find the 650s very comfortable. I can always tell they are there because of their fit, no matter how I adjust them.
