Richer Sounds exclusive model.

Great bass depth

Following on from the award winning XL315, comes the Symphony 400. Cambridge Audio has sensibly kept changes to the winning formula minimal. Yet, with a revised copper structure, the Cambridge Audio Symphony 400 has greater detail and transparency than before. Fans of the XL315 will be pleased to hear that the bass depth and impact that made the old cable so popular, remain.

For a good quality speaker cable with class-leading punch, the Symphony remains top of its class.
Rated 5 out of 5 by from The Finishing Touch... After my recent (Richer Sounds) purchases of Turntable, Amp & Speakers, the guys were spot on (again) with their advice of cable. Loving my new set up!

Rated 4 out of 5 by from Good value cable I purchased 16 metres of the Cambridge 400 after scanning through the reviews on the RS site. I wanted to bi wire my current QA Concept 20 speakers and so far everything is sounding good with plenty of detail in the music, both vinyl an CDs. Whether or not this is down to the new cable or the bi wiring, who knows? What I can say however is the cable I replaced (Chord) which if I remember correctly cost around £5 per metre, sounded no better than the Cambridge at £2.79 per metre. Pros- delivers plenty of detail and clarity. Cons- It's quite a bulky heavyweight cable, especially if you intend to bi wire speakers. Invest in a sharp knife for exposing the + and - wires as the plastic is very thick,

Rated 5 out of 5 by from it's a cable This speaker cable uses analogue technology dating back to early electrical impulse technology to allow analogue waveforms to be transmitted to your chosen speaker from your chosen amplifier. Without it my speakers wouldn't sound the same or at all.

Rated 4 out of 5 by from Great value cable Hard to fault although stripping the plastic sheath off the copper was challenging if one doesn’t have a proper stripping tool

Rated 5 out of 5 by from Excellent Value I bought this on the advice of my local Richer Sounds shop. Very pleased and it give great sound quality. One cable is printed so is easy to identify. You have to be careful when stripping the cable back though.

Rated 5 out of 5 by from Great value My 30yr old plus speaker cables whilst v good quality then, and still working OK, were looking dog eared (and cat chewed) so had to go. Obviously RS the go to place. Looked at the Symphony range and decided on the 400s. The diameter of the copper wire looked closest to mine, and this turned out to be about right. Was not sure about the sheath colour however a little less pink in daylight, and better than a solid black or white IMO.Teamed with the Cambridge Audio premium banana plugs which were a doddle to fit. + and - marks on the cable sheath avoid errors. Overall very pleased with product, price and service. Thumbs up to Sebastian at the Maidstone branch for his assistance.
