post #2431 of 3013
Ok so IAM new to this forum,I've had my pm 1 now for 3 weeks,I notice after hrs of listening to them, sound is more open and more detail, plus deeper bass,also own bdp-105 ,I been listening through my ipod5,over the the 105,only because it sounds flat,until the ha-1 comes back out,Silly question will the ha-1 performed better then the 105 itself headphone jack? Other then that I am loving my pm 1,also own Bose qc15,Martin Logan Mickros 70,they don't come close to the pm 1..

Welcome.  The PM-1 doesn't require much of a headphone amp output, its extremely efficient.   You only would acquire the HA-1 to provide additional playback capabilities over the BDP-105 if using asynchronous DAC, bluetooth for example with a computer/laptop or you intend to utilize more power demanding headphones.   Otherwise the BDP-105 will work fine for you.

Forgive my noobish question, but I'm curious: those of you with the PM-1 and the HA-1, how much would you say does the HA-1 improve the PM-1's sound?


What I'm getting at is this: I've got a pair of Beyerdynamic T5Ps and I'm looking to get an amp/dac combo to go with my iMac for home listening.  I am also interested in a pair of PM-1s, but I'm not sure which I should buy first, the HA-1 or the PM-1.

NOTES from my first audition of the Oppo PM-1, excerpted from the Martin Logan Mikros 90 thread:

 

I initially strapped on the Oppos with negative bias and concordant expectation based on some of the reviews I had read beforehand, but by the end of the [long] evening and about 20 discs later, I had a difficult time taking them off and putting them away.

 

I listened to the PM-1 almost exclusively with the velour pads.  A warmer, fuller [and somewhat meeker] sound with the velour- versus the lambskin pads, IMHE.

 

Preliminary a/b versus Mikros 90 [Yes. I realize that the MLs are closed portables.] :wink:

The Mikros 90 certainly held their own, but the decisive point came when I started playing older '70s recordings.  The MLs were less forgiving than the Oppos [and/or not as well matched with the Lehmann BCL].  However, with the Oppos "forgiving" was not synonymous with syrupy/euphonic, bland or homogeneous.  The PM-1 presented these recordings with remarkable deftness, clarity, resolution, and a disarming ease.  This phenonenon reminded me of my first foray with the Denon AH-D2000: older "classic" rock and pop recordings, rather than sounding harsh or thin, sounded musically rich and well-recorded.  [The PM-1 resolve appreciably better than do the D2K, BTW].

 

PM-1 bass: rounded, warm and liquidy, with a judicious measure of midbass weight and lick, excellent micro-dynamic texture and good reach [though ultimately not as dense, percussive and cavernous as the Mikros 90]. 

 

PM-1 midrange: pure, refined, detailed--nuanced in its resolution--and [again] liquidy. 

     [The PM-1 emphasis is on refinement, while the Mikros 90 emphasis is on candor--a more "stark" (but with a positive spin) sort of clarity--with a bolder front and more overall midrange musculature/"carry".  I realize that this is an odd observation, given the fact that the PM-1 are themselves "midrange-forward" in character. But this may be due to the ML's well-integrated treble edge which lends to the Mikros 90's more even-handed--and excellent in its own right--midrange advance.]

 

PM-1 treble: delicate, refined, nuanced and smooth--for me "smooth" does not connote a muffled or blunted treble; "effortless" or "easy" might be a more apt descriptor here.

     [The Mikros 90 have a more rawly energetic/vivacious treble, which seems to better support/carry musical passages rhythmically, at least for me].

 

Some additional [treble] commentary:

The Mikros 90 [Stock Pair #3/opened May 2014, w/HeadphoneLounge UPOCC copper litz re-cable] better suit my listening tastes with respect to their high frequency presentation and dynamic/ambient reach, but I was able nonetheless to make the adjustment to the PM-1's "golden mean" or "optimal modicum" way of keeping practically everything intricately balanced.  I would not classify the Oppos as "rolled off" in the treble per se, as-in "lacking extension" or as-in "lacking detail", but I would describe them as being reticent/reserved in the upper reaches, yet all-the-while remaining highly resolving and remarkably refined.

 

Given my longstanding predilection for an "airy" and treble-leaning [many would call it a "bright"] sound, this is precisely where I feared--based on those negative facets of the reviews that stayed in my mind--the PM-1 would grossly disappoint me.  But I am glad [and, frankly, surprised] to find myself truly enjoying the Oppo's treble response, even though it is neither what I expected nor even what I thought I would otherwise have preferred: a welcome serendipity!

 

PRaT:  The Mikros 90 get the clear edge in this department, the MLs offering a more robust, sinewy and straightforward dynamic attack.  I really enjoy these unassuming little closed, portable gems!

 

At any rate, I think I could live with the Oppos for a while.  They are a worthy full-sized, open complement to the Mikros 90, and the first set of planars that have really managed to turn my head in quite some time.

Personally, I would go with the HA-1 if you are enjoying the Beyerdynamic T5Ps.

IMHO Tyll Hertsens did a impressive job going into detail about the PM-1 Planar Magnetic Driver Design in the above InnerFidelity PM-1 review. Nice!

Yeah he always has awesome write ups. He really knows his stuff. That's a huge deal for me that he knocked the LCD-2.2 off the wall of fame for these. I wonder if it was overall sound quality or more because they are similar enough to where the pm-1 wins based on ergonomics and comfort. Really hard for me to decide between the two. :/

If you've watched his conversations in the "Future of planar magnetics" panel at the THE show at Newport, you can note that Tyll really wants the planar magnetic headphone industry to push forward in terms of innovation, and Oppo really conquered several difficulty aspects (traditionally low sensitivity, high weight, portability).

Yeah watched this last night, good thing Tyll was on that stage, that would have been even more awkward without him. :dt880smile: Alex looks hung over...

That's a pretty big attention-getter. Kudos to OPPO!

And no "poo" references, either.
