Impact of splitting analog line outs 2 or 3 ways on a SB2?

I have a squeezebox 2 and want to split both of the analog l-r outputs each 3 ways due to the following:

1st splits goes to analog l/r ins on an onix h34 tube amp
2nd splits goes to l/r lines in on a rocket ufw-10 amplified subwoofer (only has line level in, no speaker level in)
3rd splits goes to l/r line ins set of self powered set of speakers in another room.

unfortunately there are no digital inputs on any of my amps, etc. so I can't make use of the digital outs on the SB2.

I don't understand the signal math so I thought I would ask here:

Does this degrade the analog out signal from the sb2?  I think it's analog outputs are 6vp-p, 2.12vrms, 100db snr, thd .003% FWIW.

What is the impact of splitting 2 ways (amp and sub only) instead of 3 (amp, sub, remote selfpowered speakers) an d of the order of the split (1st amp, 2nd sub, 3rd self powered speakers)?

Also, I had seen another option where I could wire the sub with speaker wires to the speaker out terminals (on the same post as the main unpowered speakers) on the h34 amp, and then insert a speaker to line level converter (partsexpress 302-307) to get line level to the sub.  I had heard from the amp company that it may be better to split the line out's prior to the amp (as mentioned in the questions above) rather than to split the speaker level out, but they weren't real sure.

Anyones help on this would be appreciated as it seems theres a lot of people here with the details.

Thanks in advance for your help.

FWIW Slim Devices technical support advised me recently that the SB2 should be OK to drive a main amp (47k input impedance) and active sub (30k input impedance) simultaneously from the analog outputs.
