In which case, the Burson® Soloist™ may be a satisfactory alternative to the Oppo® HA-1 headphone amplifier; the XONAR® already has an excellent internal DAC and can cascade through either the HA-1 or the Soloist™ via the dual-RCA ("2 Speakers") outputs.

On being 'more' invisible......I was of course, being ironic!

 

But, on serious note, it reminds me of a Paul Horn record, recorded in the Taj Mahal, where (apart from an amazing  20 second echo!!) the sound of a distant firework display is heard. And studio in London where you can hear the rumble of the Tube-trains under the building!

Maybe I have missed it but have there been any comparisons to HE-500? I am looking for a comfortable replacement for those.

Then you'll want this:

Thanks for your suggestion. So the PM is not it? I just want a good build quality and not having to send stuff back every 6 months for repair.

I can't attest to the build quality but the sound signature you're looking for is the 400i if you're trying to match the he500.

Anyone have an occasional hiss or vibration (tizz??) sound coming from their PM-1??? I can't nail this down and am trying to figure out if it is in the recording or something defective with my cans. I hear it on bass heavy tracks.

I would absolutely recommend the PM-1 for anyone concerned about comfort, especially with the velour pads. They feel great. And they sound comforting like the HE500s (that I have and like, but

now they sit unused while I play my PM-1).

Check to see if you have a hair on the diaphragm.

It's very common actually.  A week long course of penicillin should clear that right up. ;)

Is it very loud that during the diaphragm's excursion it is hitting the stator?

Reading over this thread and the impressions thread on the Oppo HA-1, I came to some conclusions about the comparisons.

 

Once a set of phones hits about $600-800, and an amp and DAC combination hit the $1000 range, many people seem to forget the price and start comparing apples and oranges.  The PM-1 is $1100 and the HA-1 is $1200 (amp and DAC on one chassis).  So the pair is about $2300.  That's a hefty chunk of change for many people.  But others seem to forget price, for reasons I cannot fathom.  

 

Many of the negative Head-Fi postings and some of the external reviews seem to fall into two camps.  One camp treats the Oppo products as an all-out attack on the state-of-the-art, without regard for price.  A second camp seems to focus on the Oppo products as not good enough to justify the higher price when going from lower-priced equipment.  This is a very strange dichotomy.  The positive postings seem to be far more cognizant of price.  

 

For example, perhaps because the PM-1 is a planar, it gets compared to planars ranging from $600 (a point at which the Oppo PM-2 will compete) all the way up to almost $2000 for the LCD-3 and three times that for the Abyss.  And then we see comparisons to the dynamic Senn HD800, which goes for $1500-1800, and needs a significant investment in an amp/dac to perform well; and even exotics such as the electrostatic Stax SR009, at $4100, which requires many thousands of dollars in associated electronics.

 

When you factor in the cost of an amp and DAC, or an all-in-one combination, the inconsistencies in the comparisons become even more pronounced, especially when many of the comparisons to the HA-1 are to front ends that range from 50% to more than 400% higher.

 

I just don't understand why the Oppo products are prompting such a strange reaction.  Maybe it is because they're seen as a large company that is an "outsider" to the headphone community, although they're far from a huge audio company.  Maybe it is because they've redefined one of the points of diminishing returns for a headphone/amp/DAC setup.  Just not sure...

 

For me, what matters in a purchase like this is (1) how well the product lets me enjoy music, (2) the quality of the design and materials, and (3) how comfortable they are.  The PM-1, like the other headphones from $600 to $4000 or more, makes compromises among those three factors (of course, all headphones do).  I happen to like Oppo's balancing of these factors very much (and enough to change my avatar).
