A worthwhile upgrade

Very pleased with the cables and service. Cables are always subjective and very dependent on an individual’s taste. I found the Rubies to be very transparent offering more detail than my previous cables. It was like an upgrade to my phono stage.

Thank you Antony for your comments, very happy to hear you are please with your Ruby cables

Great value cables

Much like the Diamond series these are fantastically detailed cables with a wide open sound stage though the Diamond do have a slight edge over them. I'd call these extremely neutral. They're not bright sounding, nor bright nor warm. They just let the signal through unimpeded.

This is by no means a bad thing. It simply means that if you want colour you'll need to add it elsewhere in the sound chain.

Very Happy

Firstly...very helpful and easy to deal with. Cable is a great build quality and in my system has bought out more of everything...in a very good way. Very natural with more dynamics and detail. Increased width and depth of sound stage. Was using good quality "brand name" cables costing many multiples more than these. Very impressed. Waiting on my speaker cables now!!! Highly recommend.

A high quality silver cable reflecting the inherent character of your system/component

I’ve only just started breaking in the new ruby cables and I know they won’t disappoint. My 2nd purchase from Warwick and again prompt delivery and well packed product. The previously purchased Diamond cables make my new streamer sound open, resolving and transparent. All silver cables aren't the same, Warwick’s cables are beautifully made and natural sounding. No edge, brightness or harshness, just instrumental fullness and detail. A magnificent cable for twice the price. Buy Aussie I say.

superb cables highly recommended

I got a pair of these interconnects for my turntable, the build quality is just incredible hats of how do they sound well, deep more extended rich, bloody fantastic. I wouldn't hesitate to order again and fit out the rest of my system with Robertsons cables.
