Most effective tweak so far

[GuillaumeB]

Hi guys...

Today, after couple of hours work, I had an electrician lay a dedicated power cable to my listening room. 

Now the system has its own fuse, a regular 20amp Siemens, and 10 m long Neothech NEP 3200 feeding the Torus Isolation Transformer directly.

It is like listening to a whole different system now. 

If you have the chance to do something like this, strongly recommended. This is by far the best money I spent on my system.

The cable is not cheap, and I really cannot comment whether it is the best option since I did not have the chance to try anything else. 

Explanation from vhaudio:

The Neotech NEP-3200 is a 9AWG UP-OCC (ohno continuous cast) Copper AC power cable, that uses 16 solid copper wires that are each 17 AWG. Each of these solid core wires is individually insulated with FEP (fluoropolymer) insulation. Each wire is woven around a fiber-filled PVC core to maintain structural integrity, and minimize conductor movement. The Neotech NEP-3200 is among the best bulk cables on the market, and is especially ideal for high current amplifiers, as well as feeding power strips or line conditioners. Use the 6 red color-coded conductors for 'hot', 6 blue conductors for 'neutral', and 4 black conductors for the 'safety ground'. Total O.D. is .614" (15.6mm).

Cheers...

I use bog standard 6mm Twin & Earth wiring and have 8 dedicated mains spurs feeding my hi-fi (each Devialet unit sits on its own circuit). These all connect back to a dedicated hi-fi consumer unit which is completely separate from the house electrics. Each circuit has it's own RCD circuit breaker. 

Might sound a bit OTT until you hear the difference it makes. Perhaps the most cost effective upgrade I have carried out. 

I probably didn't need so many spurs but I wanted to future proof my setup if that makes sense.
