I wanted to offer some reflections on the WP900 in comparison to the MSR7B. I’ve already posted an earlier version of this on the MSR7B thread, but this is an extended set of impressions of the WP900.
First, these things are absolutely beautiful. I already have the ZMF Eikon, which many people including myself regard as fine looking headphones. They are. But I have to say, the WP900 are probably the best looking headphones I’ve seen. Despite being a flamed maple finish, they’re actually not overly “flash.” I know this finish and the factory where they come from quite well as I have MIJ Fender and a Charvel (for hair metal fans) both from the late 80s from that factory. I tried to take some decent photos, but the battery on my Lumix died. You get the idea, though. See below. The build quality is solid without in any sense being bulky. They are light and the rotating hinge on the cup feels smooth and solid. I understand the chap who designed the MSR7B also designed the WP900. The structure is similar, though the materials are of course different. Pads are very comfortable as is headband. It's amazing that the cups house full size 53mm drivers in such a small unit.
To the sound. When I bought these blindly, I was expecting them to a more refined version of the MSR7B. The MSR7B are excellent headphones for the price. Their technical attributes are outstanding and probably deserve more recognition. The WP900 is quite a bit warmer than the MSR7B. Bass is more accented. Probably by 3db in the 80khz region. This gives them more slam and impact. They handle deep sub-bass remarkably well. Potentially problematic tracks – much of Hans Zimmer’s late output, for example – can cause distortion and clipping in some headphones. My Focal Clears actually distort when pushed too far, which I don’t recommend doing. The sub-bass and bass on the WP900 is detailed and controlled. A track like “YYZ” by Rush or “Teen Town” by Weather Report is a good test. It’s a beautiful experience on the WP900. Deep, impactful, and textured. Kick drums and bass guitars are powerful and layered. Zero bloat. Massive Attack’s “Angel” is another good test track. I’m listening to it now and I hope people get the chance to try this out – because it’s sweet.
But these are not “basshead” headphones. There’s zero bleeding of the bass into the mids, which I welcome. I’m a fan of the Beyer sort of bass – tight, controlled, and with an accent on sub-bass. I don’t like mid-bass and especially when it’s flabby (I think here of the Nightowls and to some extent the Campfire Cascade when they’re unmodified). Mids are superb; lush, detailed, full. There is no recession. Male vocals are present but not shouty. Guitars are powerful. I’m listening to a 32/192 WAV rip of the re-mastered issue of Van Halen’s “Fair Warning” (arguably the greatest guitar tone of all time). The tone is rich, organic, and immensely satisfying.
When I first plugged the WP900 into my WM1A, my first sense was the WP900 does not have the peaky treble of the MSR7B. I have to say, I don’t mind a bit of sharp treble, not to the point of sibilance, but I’d rather have too much of a peak and lower it in EQ than not enough. I have now had a good day or so of listening fairly solidly to the WP900 and find the treble to be balanced, detailed, but not fatiguing. One of my test tracks for treble is Dio “Holy Diver,” especially the cymbals and high-hats which can be piercing on the wrong headphones. Here, they are close to perfect. When I’m not listening to Sibelius, Bruckner, or Mahler, I listen to a lot of supposedly “bright” rock/metal from the ‘80s (hey, boomer). It all sounds superb and detailed on the WP900. Immensely pleasing.
Soundstage and imaging are indeed outstanding. The final movement of Mahler’s 2nd must be one of the most demanding pieces of music to reproduce in any recorded format; I have quite a few DSD/SACD recordings of this symphony and the level of clarity, detail, and precise imaging on the WP900 is outstanding. The same is true of complex passages in progressive rock and metal. Listen to Dream Theater’s “Images and Words” with these for a good exercise in imaging and separation.
They pair exceptionally well with the WM1A. I already thought the synergy between the WM1A and the MSR7B was excellent – no EQ needed. I find the WM1A is actually quite a picky dap. My ZMF’s and my former pair of Sony Z7M2 sound tepid and just “off” with the WM1A, even when run through a powerful amp. But the WP900 just works. They really come to life here. I also want to add that the WP900 scale exceptionally well. I bought them mostly for portable use, but when I plugged them into my RME ADI-2 and Pathos Aurium, I was pleased to hear that they sound excellent. This is an amazing combo. On my desktop set-up, the WP900 are exceptionally snappy and precise. They could easily be one’s main desktop cans, without a doubt. Out of interest, I just A/B’d these with my ZMF Eikon. The Eikon are definitely more technically proficient headphones, more spacious, better detail retrieval, but the WP900 are not far behind.
Hope this helps those interested in these fine headphones; happy to provide more info if needed. Excuse any typos.
