WhatHifi use to be one of the places to get real reviews and real good advice on products that were good value and produced good sound.
Now they are the worst place to get any advice or product recommendations because they are using manufacturers to pay their wages and all the ad revenue from them too. They stopped being good in the 2000's from what I remember and were good before that and their advice was top quality, now they recommend products based on their ad revenue and manufacturer sponsoring.
Be warned some of the products they state are better than X are normally the worst one and the X product is miles ahead but of course no ad revenue or sponsored by the manufacturer, it changes from year to year there now. So be warned WhatHifi is not what it was and a respected place to get information on value for money or good products.
Regarding the USB cable listed well that is just a bad joke there are many audiophile USB cables with good shielding for less than £25 and they are only worth it if you have interference from Radio or electrical noise, if not a standard good quality USB cable for £1-£5 is more than good enough for audio over USB.
I won't get into the discussion regarding speaker cables as in other threads as digital is one thing and analogue is another, Digital in most cases is if it works it works end of, analogue cables sometimes paying more is worth it because better quality cable, looks nice and reduces power loss for long runs and same applies for HDMI which is digital and benefits with better higher rated cables for 4K (HDR,WCG) and high bit-rate lossless audio, to stop drop outs or handshake issues, but again as with digital cable if it works it works and no magical better quality cable will make picture or audio better. If you spend more it is just a matter of better materials, better quality build on the cables and may look nicer (so jewellery for your audio gear basically).
