^ That brings up a good point though, about Oppo and how they have a 30 day return policy.
You can buy and then if you don't like them, just return for a full refund within 30 days and you are only out the shipping charges.
I don't know of any other OEM of these types of products that offers such a generous return policy.

It also of course depends on what headphones you are using. You will need some very high quality cans like the PM-1 or PM-2 to hear the difference.
I think the balanced output are superior to the unbalanced on the Oppo HA-1; even at matching audio level. The balanced just sounds better.

This is what Oppo says about the HA-1 ".... All single-ended outputs are derived from the balanced signal as well...."


This means the SE output is derived from the positive leg of the balanced output, so how can the SE output sound inferior to the balanced output since its the same signal? Just curious...

It is the same signal; but only half of it By switching between balanced and unbalanced output (with same headphones; I could with ease hear which output is being used). Just tested by having another person selecting output and setting matching volume level. (pausing the music during switch and volume adjustment).

Edit:
Keep in mind that balanced is not only lower noise levels; also increased dynamic range.

Here's some info from using all of the PM-1 pads on the PM-2.
More info from Tyll on using them with the PM-1 soon.

I have. I prefer them. The sound is more open on the high end and seems a bit more defined in the lows.

There is a good comparison with measurement in Innerfidelity:

The difference sounded more pronounced than the measurements might look, but then again the scale is pretty large.
If you have PM-1s, I recommend signing up for them.

I just picked up a set of the PM-1 headphones a couple of days ago.

These are my opinions thus far. Feel free to agree or disagree! This is more of a first impression than anything. I am really pleased with the purchase and grow more so as I spend time with them.

Sources: various sites and media across my PC utilizing an HRT microStreamer as well as some time with my OPPO BD-105

I was a bit dissapointed with the BD-105 headphone amp. A bit dull and lifeless versus the HRT.

In that I haven't spent much time with recent high end cans, I will have to compare these to my Wilson Watt Puppies. Sorry for that!

Pros
Smooth
Fast
Neutral
Non-analytic
Extreme comfort
Detailed
Absolutely effortless
Micro-details are clear and precise


Cons
Versus the W/P - they lack the base punch - this may be the fault of the lack of a real amplifier.


Summary
Very easy to listen to for hours on end with no fatigue whatsoever. I keep wanting to hear just one more cut.

I preferred the sound and comfort of the velour pads over that of the lambskin set. Not by very much though. Both are viable options and I will probably spend more time investigating this in the near future.

Notes
Once the holiday mess has settled I expect I will purchase an HA-1 and a balanced cable. I expect that this will really be a boon to such a pleasurable headset. More to come as I get more time on them and decent amplification.

I do want to stress that the HRT really does shine with these if you are in the market for an affordable/portable USB DAC amp device.

I have a pair of these excellent headphones.

Now I want to get a stand for them.

Has anyone tried a Sieveking Omega with the PM-1s?

I like the way it looks better than the plastic stand from Oppo, but (presumably) the stand from Oppo fits the contour exactly. The measurements for the Omega show it at least a half inch narrower than the chord across the PM-1's headband. Which means for all the graceful bentwood construction of the Omega, it might be not much better than hanging them off a coathanger (because if the contour doesn't match, then the weight isn't evenly distributed on the curve, only on the apex).

I asked the same question on head-fi and a person tried their PM-1s with an Omega. They said it fit okay, but only if they expanded the headband all the way, otherwise it pinched the cups. So no Omega for me. Ordered a stand from Oppo.

Picked up the stand today. Fits perfectly. And looks way better in person than it looks in any photos I've seen.

Hi

I have three questions regarding pm2. Could anyone help me with this?

1. Can I just plug into my receiver to listen to my movie w/o buying oppo's HA amplifier?
2. Can you hear 5.1 like surrounding sound using pm2? or pm2 is just for two channel stereo music?
3. Does it have longer than 16.2 ft (5 meters) cable? or even wireless?

Thanks.

1) Yes, as long as your processor has a headphone output.

2) The Oppo headphones are designed for 2-channel audio, and devices like a BDP-105D or your receiver
are designed to downmix any multi-channel audio to 2-channel audio before outputting said audio over
the headphone output. The quality of sound out of any given headphone output is dependent on any given
piece of gear and the engineering and construction of said gear.

3) No, but you can buy longer aftermarket cables that will work the headphones, and prices range from
inexpensive to very expensive. The Oppo headphones are not wireless capable either, but again there
are aftermarket device that you can place between the headphones and audio device that can render
wireless capabilities. Usually most devices like that will downgrade/compress the quality of audio though.

Yes it will be interesting if they are worth the full MSRP!
well? are they?

I have the HE500 on order a few weeks now based on your avatar and previous conversations with you. Should have them by next week. I was going to go with the HE400 but with these models discontinued I was able to pass on the Oppo PM1 and get the HE500, PSB M4U 1 High Performance (highly regarded) and I have $300 left for ear phones for my Pono for walking in the park.

Any suggestions on the Pono buds? I have a thread here. Don't really like the suggestions yet.

(the PSB are not yet ordered, have them on my watch list)
