<<help decoding these specs and opinion on compatibility with the cubes...
Output Impedance <0.8 ohm
Damping factor >10>>

Yup, DF = 8 ohm/0.8 ohm = 10

Here are some other amps for comparison:

Mola Mola (Class D) = 0.003 ohm, so DF = 2666  <== avoid
Bryston 4B (Class AB) = 0.016 ohm, DF = 500  <== avoid
Aesthetic Atlas (zero feedback hybrid) = 0.25 ohm, DF = 32
FirstWatt SIT-3 = 0.26 ohm, DF = 31
FirstWatt SIT-1 = 0.27 ohm, DF = 30
LTA Z10 (ZOTL) = 1.2 ohms, DF = 6.7
Audio Nirvana 300B SET = 2.7 ohm, DF = 3

Thks guys. 
I was sure these specs will fit well the cubes.

Hi everyone,
I had planned on purchasing the Cube Nenuphar 10 this fall for my 14 x 18 room but my system is now being relocated to a 11 × 12 room.  Is this room to small the the Nenuphar 10's?  Should I being looking at the Nenuphar 8's instead?
@bobheinatz Bob, I would personally choose the Nenuphar Mini (F8 Neo driver) speakers for that sized room (11 x 12).

Keep in mind, I have my Nenuphars (10s) pulled way out into the room and listen to them in a somewhat nearfield position. My room is 19 by 26.

Perhaps those who have their Nenuphars placed much closer to the front wall will provide their recommendations?
Dave,
Thanks for your opinion.  My guess is also the F8's would be a better match in that room. Any one else with experience in a small room?
