How Big of a Difference?


Hello all,

I have near completed upgrading my system, but have left my speaker wire the same. My system is as follows- Laptop (Tidal) > Schiit Gumby Multibit > Freya S > Vidar monoblocks > speakers. My usb cable is Supra usb, and I am using xlr connections with amazon basics cables. If I am not mistaken, xlr is already super good at being noise resistance so I shouldn't need to spend more $ on fancy cables at my current level of audio equipment. My speaker wire is traditional 12 gauge wire I spliced from the spool. Nothing fancy. The reason I feel I shouldn't spend money on better speaker wire is because I traded the Supra usb for a super cheap usb and could not hear a difference. On top of that, I used to use single-ended connections using Chord C-line cables, and I could not tell the difference between those and cheap ones. What is everyone else's consensus? Can you guys hear a difference in your system? Thanks for the help.

@holmz let’s start with

About 11-12% of the time the mains voltage is too low to pulse any current into the power supply (Assuming that the rail is at ~28V).

The only point in time where electrical energy does NOT flow is at that point in time when the voltage passes from the +ve cycle to the -ve cycle - the rest of the time there is energy transfer

If it all happened in the blink of an eye, then how is it the tube monoblocks ran for many seconds (!10 Seconds) when the power switch was shut off?

My guess would be that tube monoblocks "store" a LOT of energy in the form of

  • electrical energy in the large transformers and capacitors used in tube designs
  • residual heat energy in the heaters of the tubes allowing sound to be heard even after the power was turned off

The resistance of copper and silver is pretty close to zero, and the speed of the electric field is pretty fast.

It’s not about resistance - it’s all about Valence electrons and the speed at which the valence electrons in a metal react in order to transfer electrical energy

Valence electrons in Silver move much more freely than they do in copper - this is conductivity

It take far less energy to make the valence electrons move between atoms and therefore the dynamic performance of silver wire is faster than copper.

then how does 3 feet of silver result in anything more dynamic happening?

As I said in a previous post - at each "connection point" (i.e. a plug) the only electrical attribute present is Voltage.so the energy that "flows" through an attached cable is dependent on the properties of the cable that the energy is about to flow through

  • conductivity of the metal (e,g, silver) used in the conductors allows the valence electrons to react more quickly resulting in a cable that is able to provide better dynamic perofrmance.

If the power cord is doing some other stuff like filtering noise, then I could understand that as a goal.

A good power cable

  • does NOT interfere with (or filter) the transfer of the electrical energy,
  • it also does not introduce noise into that cables by using
    • a geometry that mitigates the creation of induced noise between conductors
    • an insulation that that has a low dielectric constant
      • which reduces the amount of noise created in the cables due to the charging and recharging of the insulation surrounding each condcutor.

Here are three sites that may explain things better.

All I know for sure is that the specs which are rated in terms of “per foot” or “per meter”, seem to favour using monoblocks close to the speaker. So close that the speaker cables never get to the floor, always seems to work for me.

 

The only point in time where electrical energy does NOT flow is at that point in time when the voltage passes from the +ve cycle to the -ve cycle - the rest of the time there is energy transfer

I think that the input voltage needs to higher than the rail voltage (and maybe a diode drop of two extra… 

So it is like 10 degrees either side of the zero crossing where that voltage is not enough to flow into the power supply.

@holmz re:

That is certainly correct for cables that use more commonly adopted cable geometries and insulations

  • because the amount of noise created within the cable itself is lowest when the speaker cables are short

However - with speaker cables that use cable geometries and insulations that mitigate noise - e.g.In-Akustik

  • the length of a speaker cables becomes much less of an issue

Someone mentioned above, Canare 411S star quad wire. I have found that this is the best low price cable for the money! Buy the cable in bulk and buy good quality spades if they fit your system, or buy banana if you need too.

The best  high end speaker cable/interconnects for money is Analysis Plus.

I have been doing this for a long time and have a very good resolving system.

 

I always love the "your system is not resolving enough" commentary.  Frankly, any reasonably eared person should be able to detect differences on almost any system, resolving or not, IF there is a difference. It's the delta you should be able to detect, regardless of the quality of the starting point. The "resolving" comment to me is a defensive rationalization.

My usual response that statement is "or maybe your brain is not objective enough..."

I do not mean to attack those who responded in good faith, but I do want to point out to those who regularly post such statements that really they're putting themselves, and their fancy dandy systems, above other people.  It's a bit condescending.
