Hi all. For the choice of chassis, sonically, will there be a noticeable difference between a single dual mono one vs 2 separate mono chassis for NC400 using balance input?

BTW, both the NC400 and the SMP600 come with one end of the power supply cable, I.e. 12pin connector at one end and loose cable at the other end. So, I simply need to do the matching and solder the two loose ends together? If this is the case, I wonder why they don't simply provide one single complete cable. Or I have made anything wrong?

Thanks.

Oh, I have overlooked the power cable come with SMP600. It should be a "complete" one... my fault...

Yes, it is safe and this is what the mute is for.

I will state the obvious also, that the amp is still live so the speaker cables should not be changed when the power is plugged in and the amp is muted.

The difference will cannot be seen on all systems. There is a difference in imaging, staging, the precision of the instruments. However everything else would need to be clean for this to happen. For example a bad power cord will keep everything hazy so the mono chassis will not help. The same to be said about room, speaker, cables, pre and source. For home theater, a single chassis will be fine. For classical, go with mono blocks. For Rock, well. With solo's or lots of vocals in blues and jazz, the mono blocks would be more live like, assuming the rest of the system is good also.

The output is short circuit protected, so there is no risk doing that ....

I have tested this by accident, shorted one output and amp just kept muting, removed short and all ok again, good bit of design work!!

Default Choice of wire..

Hey guys,

I am planning a build with ncore and therefore I am currently making a list of the materials I need.

I don't know if this has been addressed before in this thread (I have tried to use the search function, but no luck), but I was wondering what type of hook-up wire to use for the outgoing signal, the one going from the amplifier modules to the speaker binding posts. I understand these wires will be unshielded and are to be twisted, but what type/size (alloy/awg) would be best to use? I am sure this is something that one could have endless discussions about and that this would be a point of debate among the real audiofreaks (no offence) but what I am looking for is something that would be a reasonable match between amp and materials. In other words: what would be the minimum awg and quality of the wire to not let the excellent specs of the ncore go to waste?

Thanks in advance,

Bultrug

Hi,

I used the VanDenHul SCS-12, it's nice, good quality but pretty hard to twist. I guess there will be others but this one works fine for me.

Succes!

I seriously don't think it matters all that much. Use the thickest wire you can fit in the NC400 terminals. Things that DO matter is to twist the speaker wires properly, and keep them far away from the PSU cable.
