NuForce Reference 8 vs. 9

i am, using the p-8 with my ref-9s driving tyler linbrook signature system speakers, my only tube gear is a ear 934p and at this point i am leaning to the ear over a ps audio gcph, for my ears i cant beat the sound i am getting from my setup, lots of luck with your choice in a preamp,

One thing to take into account is that you can't use a Nuforce amp together with the Gallo sub amp on the second voice coil.

This would be according to....?

for the music,

Probably according to Nuforce. I am not familiar with the Gallo's but the Nuforce guys are very explicit in their literature about not connecting their amos in ways that sum the earths or both earth ans signal and I guess that is what hartneed is saying.

I posed the following question to NuForce, via email, after reading the manual available on line:

"Do I understand the NuForce manual correctly that NuForce amps cannot be used with the Gallo subwoofer amp to biamp the Gallo ref3 because that would involve two amps driving a single speaker driver?"

Jason from NuForce responded:

"Yes, you[r] understanding is correct.
Jason"

I replied:
"Thanks for your quick and honest response."
