I really like to use the twisted pairs from plenum rated CAT6 cable, they solder nicely and come pre-twisted.
I've used coax for some phono and high gain applications and it seems to work well, the thinner RG-174 video coax is nice and easy to use as well as route, but I'm not sure it's needed in a power amplifier.

What do you mean by "signal wire"? If you mean wiring from input sockets to the circuit (or volume control etc.), then the rule is the same as for external connections: coax for unbalanced, twisted pair for balanced. However, inside a metal chassis you can often get away with twisted for unbalanced too.
Other signal wiring (e.g. from one stage to another) can be just insulated wire, as the signal will be large enough that it doesn't need protection and you don't want to add stray capacitance.

I've never seen a instance yet where some of my stray sections on mic line wouldnt work just fine. Otherwise I just chuck some wire up in the drill and twist it nice and tight.
On preamps, I usually use shielded untwisted pair similar to microphone cable, but coaxial video cable works fine, too. On my power amplifiers, I use chassis as ground, and run a single #22 wire per channel to the input grids.

Thanks for the replies. The connection is between the rca input jack and the driver board. I’ve got both shielded twisted pair and interconnect coax. I’ll probably go with the pair as that is a little easier to work with. Down the line, if I’m feeling ambitious, I might experiment trying different cables in each of the monoblocks. If so U’ll post my impressions.
Unless you're in a very noisy environment, or dealing with very, very low signal voltages I think that twisted pair should usually be more than adequate for most builds. The earlier mentioned trick of twisting your own in the chuck of a drill is very handy, and I use it with solid core for filament wiring, it's a great trick 🙂
I have build a NF-cable, unbalancer whith his silver cable Audio cables, parts, and tweaks for audiophiles - VH Audio and DIY Silver Interconnects ... it has beaten the hell out of 1000$ Kimber cables. If you want to spend the least amount for a nice silver cable with textile dialektikum, look up Jacmusic ... and build your cable like described above.
Uh, why are you posting golden-ear audiophoolery here? Careful, the thread might get moved to the lounge, as religion (and politics) is prohibited from discussion on the forum...
Besides, we're discussing signal wiring inside an amplifier here, right? Silver wire is fine, if a bit unnecessarily expensive for the job.
That second link has some hilariously expensive snake-oil parts (RCA plugs for 299$ a set?!) recommendations.

That was not my intend...the title was "best ..."
I used all kind of wires for signal within an amp and I am not relegious about silver vs. copper. If you want to stay reasonable, you will get excellent results with Jupiter solid core copper 0,4mm in cotton. Absolutely great stuff as well...today I would always try to stay with cotton, silk etc. But I used as well all kind of teflon coated cables, copper, silver, stranded, solid. On connector, WBT AG are very good, but you can as well use the asian Eichmann plug copies for 16$ from ebay with excellent results.

In the average power amp, you could use barbed wire 😛
I use these RCA connectors: 10Pcs RCA Female Jack Socket Red/Black Chassis Panel Mount Connector Ga | eBay
I use this wire: Single Conductor Cables (Hook-Up Wire) | Cables, Wires | DigiKey
YMMV, but in the average power amplifier, noise on the input isn't an issue.

What does the input wire GO to? Typically a PCB, open to the same EMI influences, and laid-out for the circuit's needs. Or point-to-point (to-point to-point to-point) construction. i.e. if the inside of the chassis is "clean enough" for the PCB, any sane length of any kind wire will be fine.
People have opinions on copper, silver, etc. Personally, in DIY, I think a nice color insulation affects "sound" more.

Cotton, silk etc. should always be avoided unless you sincerely believe that the dielectric makes absolutely no difference. This is because they are awful dielectrics whose properties change with the weather. Of course, if you believe that it makes no difference then you have no reason to choose them anyway.
Hmmm...it seldomely rains in my living room and humidity is pretty constant...temperature as well...but I will observe this now more seriously...I always though that it sounds better in the winter.
