Oppo PM-1 Planar Magnetic Headphone Impressions Thread - Page 177

Thanks jh7000.
I've been tempted by the descriptions of the Xonar in the past.
It's good to hear that it works well with the PM1

Your best bet is to check with Oppo and/or see user's manual [if cleaning is mentioned].

That said, I used diluted Fantastic spray cleaner.  I sprayed the cleaner on a soft cotton cloth [an old tee shirt]--not on the headphones--just enough to get the cloth barely damp, then wiped the outside of the ear cups, the band, etc.

For cleaning the velour pads, I use clear adhesive tape turned inside out and daub it over the velour with a slight "rocking" motion.

For me, I prefer the (SS) Lehmann BCL, w/gain set to 0db  [over the SS beta 22] with the PM-1.  More detail, deeper soundstage, better natural weight to instruments/vocals, rounder/fuller bass.  The BCL just seems to capitalize on all the inherent strengths of the Oppos.

Have not tried the PM-1 with the [hybrid] Fitz-improved Bada PH-12 yet.  The Bada will be going to the repair shop  this week [nothing from the right channel except a loud persistent hum].  ALL those 6SN7s and so little time!  : )

I've used an Oppo HA-1, Schiit Asgard 2, Burson Soloist SL, Schiit Vali, AMB mini3 (briefly), TTVJ Millet portable tube hybrid (briefly), Peachtree Nova, iphone 5S.  All sound great to my plebeian ears.  OK, the iPhone is the weak link, but not that weak, which is one of the things I really like about the PM-1.  They are one of the least particular headphones I've used, and one of the best sounding (to me, imho, ymmv.....).  For those that need to feel they "scale up" with better equipment - they do, in that they do reveal the "betterness" of better equipment.  The PM-1's themselves just don't require a fleet of high end gear to sound excellent *coughHD800cough* (I honestly don't have enough experience with the HD800 to take that shot at them, but I couldn't resist).

 

They sound better than one would expect (by a long shot to me) with an iPhone.  I was pretty impressed with the Asgard2 pairing (Used a Bifrost Uber) and with the Vali (using the HA-1 dac output).  My current is the HA-1 and the Vali running from the pre-outs of the HA-1 when I feel like a bit of tubes.  The Vali is a killer little amp as long as you don't have to physically touch it while listening (tubes ring like crazy, even with a quiet vali).  The HA-1 is a really nice, impressive all in one, but it exceeds "modest" in my book ($1,200 isn't modest to me.)  As usual, beta tester caveat - Oppo gifted a PM-1 to the PM-1 group, and HA-1 to the HA-1 group, I was included in both.  Yes, that very likely influences my feelings toward both pieces of equipment.

This may have been covered before, but I'd hate to peruse all 177 pages of posts (!). Anybody have the inner dimensions of the ear pads? If this is yet another set that will crush my earlobes, forget it. ;)

post #2646 of 3071

I get approximately 2-3/8" x 1-5/8" inside diameter and 4" x 3-1/4" outside diameter, giving a pad width of about 7/8".

My ears are medium-large and just barely make it all-the-way inside.

Oppo should be able to make/market a "roomier" earpad, building on the same "4-peg plug-in" base.

Or maybe they could just provide a blank base and let owners roll their own pads.

I prefer the lambskin pads, which fit me just right.

These survived being thrown in a bag and hauled all over Europe with nary a scuff, good durability.

Very long review with extensive images - Translated French to English - source

 

Test OPPO PM-1: A single headset of its kind! - HDfever.fr - Jacko, June 16, 2014

 

 

The OPPO PM-1 clearly left the best helmets in this price range, and even beyond. Nothing to say about its intrinsic qualities, and his musicality is very high! For the rest, as the audio is always a matter of taste, we always advise you to make tracks to judge whether his signature sound meets your expectations. HDfever therefore awarded him without hesitation 5 stars Audiophile Experience.

What I liked with the OPPO PM-1

 

  • Finish and impeccable quality of building
  • Excellent comfort
  • Proven strength
  • A standard detachable cable long enough
  • Very luxurious and useful standard accessories
  • A true and balanced listening, symbol of neutrality
  • Impeccable precision
  • No sign of distortion, even on difficult pieces
  • A copy stereo sound
  • Its versatility and ease to be amplified (even if it is on)

I regretted that with the OPPO PM-1

  • A slight lack of ventilation
  • Can get a little analytical following implementation
  • The helmet holder would have been more useful than the varnished wooden box
post #2651 of 3071

Yes. The Oppos can get "a little analytical", but they always remain--at least for me--predominantly and preeminently MUSICAL.

The PM-2 has a very energetic and sweet midrange.  One of my favorite parts of it, but the midrange is a little colder in nature. 


Statements like this make me wonder if every PM-1 floating around sounds the same.

 

I eventually returned my PM-1 because I thought the bass rolled off too early and was lacking in power and impact, particularly at the lowest frequencies.  I know I'm not alone in this impression, the InnerFidelity review noticed it, stating that "mid-bass and below seems very slightly loose, low in level, and rolled-off."  Even the HeadRoom FR graph shows roll off starting around 100 Hz.

 

I'm no basshead and I wasn't satisfied, enough to the point where the bass was the sole deciding factor in the return.  I see no way an actual basshead could be satisfied with these, assuming all PM-1s sound the same.

I don't think the bass in the PM-1 is lacking at all, it just sounds natural to me.
I am a big fan of natural/organic sound. Coming as close to the original recording as possible is how I want my audio reproduced.
If I want to alter it from that, then I would do that with an EQ.
I also prefer to have my bass a few dB higher than that of a flat response. Not a basshead per se, but just a little bump for my personal taste.
Having said that, most music I have heard did not leave me wanting more bass with the PM-1
Only on recordings where it seemed bass was lacking a little, but that would be the fault of the recording, and not of the headphones.

Just a few notes...  The PM-1 is not a neutral can which means that it won't reproduce the original recording as close as possible...  The majority of modern music is actually recorded unnatural, colder (and more fatiguing) than they should be unfortunately...  To reproduce the original recording would reproduce all of that...  Which is something that a natural/organic headphone (PM-1 as an example) will not do, rather it'll attempt to mask this which is actually preferred more on average nowadays ;) 

 

However, it will give you the few dB higher than flat bass (and midrange) response you wish for which is more natural sounding, warmer, and easier to listen to.  The PM-1 should not leave you wanting more bass on any circumstances really due to its signature.  Note that this more natural sounding/warmer signature is what Olive and Welti discovered to be the preferred signature for most audiophiles, which is why it's enjoyed by just about everyone :p 

 

With that said, I do agree with your impressions of the PM-1...  The bass isn't lacking, and doesn't roll off that early, though it does have a slight low-bass focus that gives it a bit of warmth, thickness, and body.  But it does have good depth despite the fact.

What I actually meant by original recording, was the audio that is on a disc or file or stream.
It would be literally be impossible to reproduce the exact master tapes that aren't even there, lol.

The warm feeling that some people describe, is what I feel does sound natural and neutral.
To me they are the same thing, so I guess I am not understanding what you perceive to be different between them.
Yes audiophiles prefer that sound, because that is how the media sounds.
To alter the sound for a preferred "sound signature" is altering how the recording artists intended for it to sound,
and if any given listener wants that, it can easily be accomplished with an EQ.

(Now, I know that whole how the recording artists intended comment is a big can of worms,
since we have to deal with sub par mastering of media and just can't always get the quality we want out of the media that is available,
but for arguments sake, we can use the example of an optical disc, and then say that whatever is on the disc should be reproduced without alteration.)
