My HD555 experience (so far) - Page 3

Nope, one excellent example of fairly low impedence but very inefficient headphones would be the HD 570's. They are only 64ohms but extreamly hard to drive. While I can take the HD590's to ear splitting levels on my PCDP, the 570's are barely audiable. What's more, when I took my step-father's pair of HD 570's over to Iron_Dreamer's Apt. and plugged them into his Gilmore amp, he was shocked when he had to turn them up louder than the HD600's to get adequate listening levels.

what is important is HIGH sensitivity/Db and efficiency.
Generally, low ohms on Commercial brands only are easy to drive like panasonic and pioneer and sony.

I don't know what you guys are using the 555's for playing them on a regular basis, but to me, they really need an amp. I bought the 555's because i thought i wouldn;t need an amp to begin with, but now i definetly think i do. Im regretting the fact that i didn't get the 580's scince now im going to need an amp anyway. And they were only 10 dollars more.
I own the 595s and am enjoying them immensely without owning a dedicated heaphone amplifier.

SB Audigy Basic: Decent sound, but somewhat thin. A little distortion and they just don't get that loud, even at maximum volume.

SB Audigy Basic -> Bose Computer Speakers: They were a gift OK!? These seem to give a little boost through their headphone output. Better instrument separation with a significant boost in maximum volume.

iRiver ChromeX: The El Cheapo iRiver CD/MP3P (I think I bought this for $60 after rebate last year!) with 14mW headphone output. Sounds about the same as straight out of the SB Audigy Basic.

Panasonic DVD-S25 (pretty new) -> Pioneer VSX-D307 Receiver (about 6 years old): Goes plenty loud but the sound quality is definately below average!

M-Audio Audiophile USB: Cleaner sound than the SB Audigy but there just isn't enough power for a good bass response.

Audiophile USB or Technics SL-1200 M3D Turntables -> Allen&Heath Xone:32 DJ Mixer (400 mW output): One of the best headphone outs you can find on a DJ mixer. Very clean sound that gets plenty loud. This is my best amplification but I can definitely hear room for improvement with a dedicated amplifier!

By the way this is after a good 150+ hours of BASSY burn-in. (Don't stop at 50 hours!) I don't think the 555s/595s need a dedicated amp but they certainly make you want one!

I know this because I purchased the HD555's and I have the HD580's with a pimeta. HD580's sounded much better.

And you know that... how? These are new phones that have hardly come out for a month
Gee, because I purchased them and tested them out? It's not rocket science; and the hd580's beat the hd555's hands down in my books, for the same price.
post #36 of 268
Well, you could have said you owned both in your first post

So how do the two compare if you're driving them straight out of a sound card or portable player? Have you tried that?
post #37 of 268
i think the reason why 555 costs almost the same as 580 is because they are new (HD555), not because the quality/performance is identical.

me, since i dont have so much money to spare, sometimes i would look for discounted stuff (previous model) where the new lines are already in the market, so the dealer wants to get rid of the old ones...
since in audio, old doesnt always mean worse, so i think if i can get a bargain by buying previous line of product, i will go for it.

Ok, but do the 555's sound good anyway with an amp? Forget about the comparison with the 580's, do they just sound good?
post #39 of 268
Can anyone compare the 555 to the HD280 or the CD780 yet?
post #40 of 268
Tidescal I too want to know if they are good. Do they beat those hd280s? I love those. IF they are better than I am happy. I am difficult to please btw.
Why is not as good? some dudes weaknesses in it i thought were advantages. In example: Too upfront compared to hd580 some peeps said
Really? thats BETTER for me, its spacious but more in the fron row of the orchestra.
Or some people like GS said it was grainy. He then had it on sale (hd595) ..the grainy stage is OVER.
Then on another note he said, not enough slam
most hd555 owners *with amps* have said its pretty bass slammed to them.
So my guess is that hd555 is not a worse hp, maybe it just sounds different.

If it is good compared to a hd280, and still one of the top 5headphones under 200 dollars, then I am ALL IN.

TidesCAL, lol, I think we all know you like the 580 more than the 555, don't need to post the same thing over and over again

I'll burn them in for 2 more weeks, and then I'll have to return them. Still not enough treble extension or soundstage, and a noticeable lack of detail in the midrange. Well, I'll do what I can.

I disagree completely.

The HD-595 sounds like crap without a headphone amplifier...

The Rio Karma has one of the highest power outputs in all portable music players and the 595's sound inadequate at full volume...sorry

You need a good amp to get them to sound anything close to good.

If you like them without an amp then I am quite sure you havent heard anything half decent out there. No personal attack here - just telling it as it is...these CANNOT be used without a decent amp...

I don't think you will be happy with the hd600 or better or hd595, hd555 or anything if you aren't gonna buy an amp to gives these hps any justice. Try running your non powered, stereo hifi speakers out of your headphone jack, see if its gonna sound any good. (non powered monitors)

If you will not buy an amp, i seriously suggest buying sub 100 dollar phones, hd280, or Beyer Dynamic 250-80 (150)
You might think these sound better, (without an amp) but that is not justified , remember that. A high end hp with an amp will sound better than unamped mid end hp.

Yeah, I'm sure the power and impedence requirements are EXACTLY the same....It's fine if you want to leap to these phones' defense, but you might want to wait until you've actually heard them first....

The appeal of the 555, to me, was that it might sound better unamped than the 590. Maybe in 50 more hours, it will. Right now, it doesn't. If that situation hasn't changed after giving them all the burn-in 30 days will allow, I will return them. If that isn't "justified" in the view of others, then I can live with that.
