The PM-1's fine sonic performance and thoughtful attention to ergonomics already speaks volumes for their "prestige" and pedigree.
But I think the portable tote should be of a hard shell type.  The selvedge denim is handy, but does not give me assurance of full protection when moving the PM-1 about.

That's an interesting point. I never really thought about "full protection".
Like if you have the case sitting on you car seat and someone accidentally sits on it, it could break the PM-1.
Maybe Oppo should consider adding a hard case to their purchasable accessories.

The processing and decoding is done by the iOS device, while the HA-1 just does the DAC and amplification. So if you prefer the sonic performance of the iPhone through headphone outputs over attached storage with the BDP-105 and its headphone output, then the HA-1 will be the better solution. The BDP-105 can't connect to iOS devices like the HA-1 can, so if there is a preference for the iOS EQ/SF, you will need to use the HA-1 or similar device which can accept a pure digital signal from the iOS device.

One of the things we wanted the PM-1 and PM-2 to be is portable. If you look at most hard-shelled cases, they are portable in the sense that you can carry them, but they are poor solutions if you want to be able to easily stuff the headphones into a shoulder bag, briefcase, backpack and so forth. We want to encourage our users to use the headphones wherever they go, so a smaller profile case was necessary to meet our use expectations. We are extremely satisfied with how well the selvedge denim case protects the headphones and we feel that using an alternative case would not protect the headphones particularly better.

Thank you for the reply.

Time for some laboratory-controlled "drop" tests!

I hope they are able to sell extra selvedge denim carrying cases for those who are more active or careless. wink_face.gif

I like the denim case. Box went in the closet and the denim case has held my PM-1's ever since. Nice fit in my laptop bag.

The PM-1 is out of stock now at Oppo Digital.

Some have expressed the view that the PM-1 does not scale well with better equipment. In my experience, that is not true. When I first got the PM-1, I used it with an iPod/Cypher Labs DAC coupled  the Alo Pan Am amp, or with a PC feeding the DAC in the Pan Am. I thought both systems sounded good. Yesterday, I got a Grace m920 DAC/headphone amp. There was an obvious improvement in clarity, and the top end had a little more sparkle.

I think some people are so used to lower sensitivity headphones, they are expecting vast improvements from scaled performance.
While the PM-1 does scale well, you will most likely only hear small improvements since they are already so efficient.
Some people may get a little flustered when they pay 2k for an awesome headphone amp and then the PM-1 doesn't sound that much better compared to lower end models or even an iPhone.
Everyone is of course entitled to their own opinion. smily_headphones1.gif

PM-1s scale well with better performing headphone amps/DAC's, not because they are so efficient.  Read some of the reviews posted earlier concerning the PM-1 becoming more revealing with a good headphone amp/DAC. :smile_phones:

You are misreading my post. I wasn't saying they scale well BECAUSE they are efficient.
My point was that they need less scaling because of their efficiency. ...and I did say they scale well.
The need for a powerful headphone amp is only necessary for squeezing the last few percentage points of high quality sound out of them.
You're welcome to disagree, just my opinion. wink.gif

Same here.

Better source/amp bring out more "finesse" in the PM-1's resolution of detail across the board, a quieter background and a more open/"easy" quality.

Also, the PM-1 faithfully convey the innate character of the equipment itself.  For example, paired with the beta 22, the PM-1 respond with more immediacy [a more forward dynamic attack] and wider sound stage; paired with the Lehmann BCL they sound slightly warmer and smoother, with more detail and greater depth of sound field.  

The Oppo also sound excellent straight from the headphone out on the Linn Intek or even the Denon AVR-1905, but not as open, finely detailed and as well ordered spatially compared with better gear.

Not to diminish your point but even relatively cheap phones can do that (my own K612 does that well) and it's somewhat expected from hifi reference headphones I believe.

In other words, it'd be trouble if the PM1 did not do that IMO so it's nice that it does smily_headphones1.gif

I believe that warmer headphones tend to be less resolving/more oblivious of gear while most of neutral/bright reference phones tend to show it clearly.

OK.

Got it, I think.

But do you also infer that the PM-1 will scale at proportionately smaller increments than a less efficient set of headphones along a gradient of rising amp power/quality?  It sounds like you are saying that there is less room for improvement with the PM-1 versus a less efficient planar.

Agreed.  My unassuming little Mikros 90 scale up by large quanta and seem to be limited only by the source gear.

 

However, my post simply reinforced the prior post, which countered the erroneous generalization that the PM-1 do not scale up well with successively more capable upstream gear.

 

The more time I spend with the PM-1, the less apt I am to categorize them as "warm".  

 

IMHE, their pan-spectral resolution [particularly their ability to resolve subtle dynamic and tonal variation] is among the best I have heard within the cadre of planars I have owned up to this point.

Thanks for the clarification Patrick.
Off topic but are you by any chance considering the HE-560?
Would be nice to read up your comparison of the two.
