I use monster cables to connect my les paul with the effect board and the board with my full tube fender amp. Best guitar set up ever. A wide dynamic range. These cables can whisper and scream. You can find them in top recording studios.
@all
The cable question is difficult. First you have to inform yourself how different materials sound. Silver, gold, coppper. And copper has many sounds, depending on how much oxygene is in. Standard copper has another sound than very clean ofc copper with nearly 0% oxygene. And big-crystalline copper is different again as well as single-crystalline copper (professor ohno method.
But that´s not all. You can´t use any cable for everything. The capacity of your cable depends on the output resistance of your player/amp/etc.
A high end player/turntable (mc!!) is 150 pf/meter. This is the highest quality.
500 to 2000 ohms need a capacity of 90 to 150 pf/m. Lowest quality (tape for instance) > 2000 ohms needs < 90pf/m.

I use a rega planar tt with a silver cable. I built it myself to get a top quality and to save money. Although it´s the usual cinch thing, I build it as a pseudo- xlr connection. This is a perfect isolation.
I built two wall-mounts for the turntables which works fine.
My rega planet cd player ws designed not to sound harsh and too crisp. They gave him a burr brown chip to get the real analogue feeling. It´s also connected with a silver cable to the rotel pre-amp. I remember when i replaced the originl factory cable. Big difference...lol.

The pre-a. is special tuned. The original condensators were removed and replaced by really big ones which helps to have enough power reserves. Some smaller cond. were removed completely to get the signal way short and strong.
The pre-amp is connected with a high clean copper cable to the rotel power amp.
The speaker set is by dynaudio (4 ohms), connected with t+a speaker six cable (mixture of less copper amd much silver) to the power amp. I tried some bi-amping but there was no difference.
Not to forget a technics graphic eq, a sony tape deck, a behringer sound enhencement processor, a philips cd recorder and a technics tangential turntable.

My first sound system was comlpetely technics, except the speakers were lowther horns. Phantastic speakers, but the reggae bass is dangerous to them. Cause the cones only should move around 1,5 - 2 mm.
They didn´t live long. Thx to my former girl friend: she turned up the volume....and burned the coils.
My current gf got a careful introduction how to use my equipment right.
My dream would be valve pre- and power amping with a lowther sub-woofer and lowther satellites.
But first i better play some lottery....
