I am of the Doen't really make a differ5nec scholl but feel the cost of Conrad Johnson gear is more deserving of a cable price proprtionate.
So two inexpensive recent purchases
A 4 m pair of sleeved cable for £99 I haven't been able to identify it yet due to sleeving
Bought off ebay and came from a Shut Down Hi Fi Dealer.
The interesting thing is they are terminate with WBT0610 plugs, which is over £200 pounds worth.
So I suspect the cable may be something special.
Not big differences in sound but did open things up a bit.
Next ones, and I wanted to try these and decide this was my go to cable, was a pair of older Black/Blue Kimber Kable 8TC.
These were advertised at 2m so a bit short ( I need 3m) but for £40 couldn't resist
When installing yesterday they are longer than advertised at 3.0m

I Like these, as again improved space and imagery over the other two. Note slight differences but noticeable
Be interested to see comments on using the Kimber 8TC with CJ Tube Amps as they are High Capacitance
