500+ Head-Fier
Hello!
A quick update on the Oppo PM-1 Planar Headphones.
I'm working with a finished production sample of the new headphones for an upcoming review and here are some brief impressions. This is based on a review sample, so the final packaging details, etc. might be different, as they aren't shipping yet.
I was in my office when I received shipping confirmation from UPS, so when I got home the box from Oppo was waiting for me.
So, I dropped everything to open the box. First impressions, this is one heavy box for a pair of headphones!
I had my son pick up the box, and asked him what he thought was in it, and he said maybe a blu-ray player or something due to the weight.
Then I opened it up and there was a lovely soft case, with extra earpads and cables.
Finally I got a whiff of the finish on the beautiful wooden box! Just great!
At this point everything is first-class, the box, inner box, and finally the wood box.
Opening it revealed the headphones, which look just wonderful and which were lighter then I remembered or expected.
The primary cable is beautiful with a substantial cloth covered OCC cable, all fittings are solid, well-designed and as they should be for a product of this caliber. The cables have small mini-jacks that go into each side of the headphones.
I plugged in the long cable, to use with my laptop, and looked for a step-down adapter to a mini-jack from the phone plug, but there wasn't one, so I looked in thee cables in the case, and found the short mini-jack cable.
The sound is superb, and over the weekend I tried them with different gear to get a better sense of their performance. If I had to summarize the sound footprint, it would be "Effortless, subtle, neutral, but with a bit or warmth, to a believable musical finish". At no time did I "hear" the headphones or technology, they simply moved out of the way so that my experience was of listening to music, not technology.
As I type this I'm listening to the Van Morrison's Moondance remaster, and it has never sounded better!
I can only imagine what they will sound like when connected to the new HA-1 amplifier. I did get to listen to a pre-production model of the headphones during CES with the HA-1 and it was superb, but when the new amplifier is available that will complete the product cycle.
I'm pretty sure that these are going to be a hit for Oppo. Every aspect of the unit I have is well-thought out and executed. Surprisingly they are also very efficient, and sounded great with my MacBook Pro, the new Korg DS-DAC-100M, the Cambridge Audio DAC Magic, the Oppo BDP-105, and the AudioEngine D3, and in all cases, they drove the headphones without a problem, which was a really pleasant surprise.
Many of the planars I've used, such at the HiFi Man, seem very demanding of the amplifier circuit, but the PM-1's are nowhere that finicky. I did find a richer, fuller sound with higher output sources, such as the BDP 105, so I think when paired with a dedicated high quality headphone amp, that the phones will really hit their peak. My brief test with HA-1 revealed an incredibly substantial unit, and design, so I suspect that when paired with the PM-1s, it will be a positive synergy.
One last note. I had the headphones on last night for several hours straight as I worked on my computer. And.. no stress, or discomfort. In fact they were so comfortable that I kept walking around with them an forgot I had them on, and they weren't even plugged into anything!
I hope this helps. We will publish a full review on MacEditionRadio.com in the coming weeks.
