Wow, no wonder you totally screwed up the FR. I'm not sure if even 300[size=small]Ω would be safe from that thing.[/size]
Wow.
You sure you were measuring the headphone jack?
I'll have one soon to confirm, but that's a spectacular error.
OUTPUT IMPEDANCE
Objective2 amp: 1.46 ohms
UHA-6HS: 0.95 ohms
Meridian Explorer: 47.95 ohms

Are you yanking our chain!?! LOL!
47.95?!!?!?
Quick question, have you ever seen something like that coming from an amp?!?! I think the highest I saw was from a NuForce amp and it even reached 15 or so (if I'm not mistaken...)
Holey buckets. Assuming this measurement is reasonably accurate, then it would behoove Meridian to disclose it, or at least allude to the potential performance impact. I would not be pleased if I sourced this as a sole driver of headgear that is adversely affected by high output impedance. It's one thing to make a product decision that cuts away a portion of the market; it's another thing to make them find out the hard way.
Has it occurred to anyone that perhaps purrin just has a faulty unit?

Meridian seems to have handed off samples to various publications with a wink-wink
Besides, the extremely high output Z does provide a pleasant, forgiving, musical, organic sound which many people like. I wouldn't consider it high-fidelity sound though. I was actually serious when I said my VAIO out (which is actually not bad) sounded better than the Meridian.
This is why I asked if anyone has seen published specs from Meridian on this.
As to your question: Only from tube amps with switches between low and high output Z. And even then, nothing that high! (The Schiit Lyr output Z is 25ohms, but Schiit does warn you not to use it with certain headphones.) High output Z comes in handy with HD800s, which some people do understandably prefer.
Todd from TTVJ has a unit and will be bringing it over tomorrow. I'll make a measurement and post results.
On a more serious note. The only reason I even bothered with measurements is because this thing sounded so off, at least with the HE500 and UERM. Measurements are a nice way to confirm subjective impressions. Here are some interesting results:
OUTPUT IMPEDANCE
Objective2 amp: 1.46 ohms
UHA-6HS: 0.95 ohms
Meridian Explorer: 47.95 ohms
The output impedance was measured with a DMM and a resistor (used both 50 and 100ohm for two sets to confirm), not with lab grade stuff. Nevertheless, the results should be a good indicator of the actual output impedance.
Yup. 47.95 ohms. I measured it again. I couldn't believe it myself. Well, not really. I expected it given the how the ME fubar'd the UERM's frequency response and turned it into an improperly driven LCD2/3. The ME would not be ideal with the HE500 or UERM. The HE500 having lowish impedance (~35-47 ohms), and the UERM ~16 ohms? with uneven impedance throughout the audio band. Maybe the HD800 would fair better...
