My friend wants to know if the liquid spark and the mimby would be better than the chord mojo. He plans on using this with his macbook. I have no experience with the mojo or mimby, but I figure someone here would be able to give him a better answer than me. I also don't know which dac I want to pair this up with too. I was thinking of pairing this with the airist r2r dac when it's released unless people really like this with the mimby. There's always people that will sell something right after they get it from massdrop.

"Reference levels :
+9 dBu 300R 16.00 mW - 110 dBSPL @ 98dB/mW
0 dBu 300R 2.00 mW - 101 dBSPL @ 98dB/mW
-10 dBu 300R 0.20 mW - 91 dBSPL @ 98dB/mW
-20 dBu 300R 0.02 mW - 81 dBSPL @ 98dB/mW

+9 dBu 30R 160.00 mW - 110 dBSPL @ 89dB/mW
0 dBu 30R 20.00 mW - 102 dBSPL @ 89dB/mW
-10 dBu 30R 2.00 mW - 92 dBSPL @ 89dB/mW
-20 dBu 30R 0.20 mW - 82 dBSPL @ 89dB/mW

Reference data on two headphones:
HD 650 impedance 300R, sensitivity 98 dB/mW
HE-500 impedance 38R, sensitivity 89 dB/mW

Highlights
Square wave response is very near that of the Liquid Crimson.
Bandwidth is extraordinary for an amp at this price: DC to > 1.5 MHz
Well done Dr. Cavalli!"


Not the reason it sounds great but it sure doesn't hurt..dB

Wow these numbers are actually impressive for a $100 amp. These plus the impressions so far are promising. Of course who knows until we get to listen, but this may give the Magni a run for its money. Just wish Monoprice didn't gouge eyeballs for international shipping. This will most certainly slow down its adoption internationally.

Any entrepreneuring resellers want to group buy? I can facilitate Asian and Oceanic distribution...

Showed my wife and she said it was tiny. I then asked her about what she thought of the amp and she said "meh".

Okay but what about your own impressions, so far, if you have had some time to listen to the unit?

Quite satisfied with the sound so far, but it's only been about 7h. Been A/B testing it against my friend's Magni 3. Compared to the Magni, it's a bit more spacious and not as forward as the Magni. The spark also has some considerable bass thump and texture. Will share more after burn-in, both in the amp and in my brain.

Anybody have any opinions on how the HD58x's sound with this amp? Recently got interested in headphones and so far have been running the 58x's without an amp, curious as to whether I would see any benefit with the liquid spark.

Can someone please post dimensions of the box each unit was shipped in?

Thank you.

The shipping box was really large for how small the actual packaging is. I think I recycled mine already unfortunately.
