Given how the Manual and Jorge describe the Micro Amp, the underlined statement above on the Micro Amp webpage should be corrected, although it's a fine statement for the Ultra Micro Amp.

Thanks again for bringing that to my attention. I've addressed our Micro Amp website writing now so hopefully it's a bit more clear... Apologies for any confusion!...

We will also address the manual writing as promptly as possible.

Cheers,

The link to the K 1000 Manual in the AKG K 1000 product page is dead.


Some headphones measurements in the Build A Graph page give the following image:

These are:
AKG K 601 Harmonic Distortion Products & Impedance
AKG K 701 Harmonic Distortion Products & Impedance
Sennheiser Oprheus Impedance
Stax Omega and SRM-007t Driver Impedance

Also, while the graph of the Bose Quiet Comfort 2 Impedance does not gives an error, it's totally empty.

Also, as it has been already pointed out, beyerdynamic DT660 and beyerdynamic DT880 appear two times each. DT660 even builds different graphs for each of them.

And Sennheiser Oprheus is misspelled, it should be Orpheus.


Hope that helps a little

Yep, we know about the various graph display issues we're experiencing on the website...

Regrettably, things won't probably change much until we complete some ongoing server work on our HeadRoom back-end allowing for better displays of the specs/graph data... We're also currently in-process with retaking brand-new measurements of all our current headphone inventory (and even a few models we don't carry!) so that laboriously slow process compounds the issue. I'd expect its likely going to be until late 2008/early 2009 before we see everything in place & running nicely!

Thanks mucho for your patience!!

Cheers,
Jorge

Keep your portable player device and our HeadRoom Portable Micro Amp perfectly in place, completely in sight and under full control in a perfectly tidy little lump on your desk. No more picking up your player to look at what’s playing, the sweet little Portable Micro Strap kickstand will keep your music player conveniently in view at all times.
