Terminal Blocks for Speaker Wire "Splitting"?


Background: I have a "mid-fi" stereo system in a 25x15 ft relatively well damped living room as follows: Yamaha R-S700 receiver, four Paradigm Atom V3 small bookshelf speakers in the corners (using A and B outputs) and an SVS PB-1000 powered subwoofer. The Yamaha has been known to blow a couple of Atoms when mishandled. Because of that and for nostalgic reasons I will be replacing it with a much lower powered vintage NAD 3020, which only has one set of speaker outputs and of course no subwoofer output.
The PB-1000 can be driven by L+R speaker level signals which it uses as low level inputs with high impedance. So, I need to split the speaker outputs into 3 sets (front, rear and sub). The NAD terminal posts are quite fragile and I do not want to jam more than one wire into each. I am using 12 and 14 AWG speaker cables.I am keen on decent sound but accept the limitations of the above equipment (have a much better system elsewhere).
So, to my question: Is there any objection to distribute the speaker signals through a pair of dual row 15A or 25A terminal blocks (L & R) and jumpers such as here:

or even 45A ones such as here:

I would use 8 mm spades such as these:

Would sound quality be negatively affected due to this signal distribution hardware or any other concerns?
Thanks!

We use those larger terminals here at work and pump 5 to 8KW though them 24/7/365.  The smaller terminals you listed will be fine for speakers and the nice thing about these terminal blocks is you can torque the screws down.   That is a biggie for a low loss connection.   Just don't over torque them as the impedance gets larger, not smaller, when you over torque.  Do make sure those fork terminals will fit in the space provided, if not, you will need a larger terminal block. They are wider than they look!
spatialking, thanks a lot for your feedback and advice. Yes, the 45A terminal blocks accommodate well the 8 mm post spades I intend to use, the smaller 15A and 25A ones don’t. Only problem with the 45A ones is I can’t find jumpers to distribute the signals to the other poles, like the red and black ones that come with the smaller blocks. Is the sound quality you experience good enough for "mid-" or "near-hifi"? My concern is more with capacitance and inductance effects on the impedance than simple resistance - any insights into this? Thanks again!-Yoram
