The sensitivity rating of a driver/transducer is how much sound it can produce with a given amount of power. Very sensitive headphones/speakers can play very loudly and full with very little power, less sensitive headphones/speakers will need more to produce the same SPL levels.

The standard units for measuring headphone sensitivity are mW/dB, usually 1 milliwatt. Your headphones have a fairly sensitive rating of 100db with 1mW.

yes, as chipp said sensitivity is how loud a speaker or headphone will go with a given amount of power. Most speakers are rated to 1 watt. Anywhere around 90-93db is considered high sensitive for a speaker.

But that isn't the whole story. You have to look at the ohms rating on the speaker as well. Not only that, but this changes depending on the frequency (don't worry about this too much)

Lets take the speakers I just got yesterday for example:
http://www.av123.com/products_produc...s&product=23.1

they are rated at 88dB. which would be considered fairly normal. So with 1w these speakers can produce 88dB
but then you get to the Impedance of 4 Ohms. Most receivers are rated for 8 ohm speakers. So I had to be careful about what receiver/amp I got to pair with them.

When you only look at the sensitivity rating of my speakers they look like any normal amp will be able to drive them, but once you take into account the impedance you see a totally different story. Most cheap receivers or amps will go into protect if you try to play these too loud.

Now, lets look at a pair of ATH-A500's
Impedence: 64
Sensitivity: 100dB

So even though 64ohms is getting higher and harder for a sound card or DAP to drive, the cans are also very sensitive so even though you might be able to hear a difference with a nice amp, one isn't really necessary.

well at this moment in time:

SinglePower PPX3 in the living room on my equipment rack
Millet Max on my desk connected to my computer
maxed PIMETA at my friend's house
RSA Tomahawk that Z, my kitten is currently using as a pillow, also on my desk
C&C Box v2 currently sitting in it's pouch on a shelf.
SinglePower MPX3 SLAM currently in FedEx's position somewhere in CA as it makes its way to me

Now, for a rundown...
The SinglePower MPX3 SLAM will replace the SP PPX3, so the PPX3 is currently for sale.
The C&C Box v2 has a new owner, but I'm holding onto it for him until his cans get here for a little special treatment and then will go to its new home for Christmas.

So, I have 3 home amps (4 until I sell one) and 1 portable amp. I really only need 2 desktop amps, but I'm having difficulty letting go of my PIMETA as it was my first DIY amp.

EDIT: Though I guess with the extra $25 for tubes, you're getting pretty close to what you paid on eBay.
Yup . .here is a quote from that page:

# In addition to direct purchase, also available on EBAY for our customer's convenience. Please search for Little Dot Amplifier sold under EBAY seller Davidzhezhe
That is the ebay guy I bought it under. . . also $160(amp)+$40(shipping)+$25(tubes) = $225 so I saved $10 and gained a rep on ebay.

He is very nice and easy to talk to as well.

EDIT >> just noticed that the email he used when contacting us is the same as the direct purchase one . . . so he is the man to see to get one new.
