Just posting some observations, and trying to avoid hyperbole and emotive adjectives! I t is fair to point out that all of the speaker cables/interconnects are in the budget or middle range sectors of the market: that is my ball park,so have no idea or experience of what the "high end" sector delivers or promises to deliver. I also have no desire to denigrate any of the products listed,they have all(bar one) performed satisfactorily, and provided many hours of listening pleasure. At this end of the market,auditioning before purchase is basically a no no, so one has to rely on recommendations from others, advertising,or hi-fi magazines/forums. Being based in the U.K, that means in effect HI-FI news and Richer Sounds, unless one is lucky enough to be near an independent trader, and they are becoming as rare as hen's teeth. So cut to the chase....Hi-Fi news and Richer Sounds have both championed the "budget" offerings from the likes of Chord and QED, and of course the Cambridge Audio brand. I tried them all...they all did the job. Did I notice any changes? Perhaps, but they were all to subtle to quantify.Did I feel "something was missing"? No,but you know as well as I what this hobby is like! Curiosity of course won the day, and I took the plunge and purchased some Audioquest Rocket 11 bi-wire speaker cable, (I had no intention of utilising bi-wiring), paired the + and- feeds together, fed them into some good quality banana plugs at both terminations,removed the Chord speaker cable I have used for a good year or two,and installed the Audioquest cable. I think for the first time ever I noticed a palpable difference, although I would be hard pressed to define that difference...."better" or "different" is very subjective! I have fairly recently had a birthday,and was in receipt of some gift vouchers, which I have just used to purchase a set of Rega's Couple Two interconnects...they arrived late last night and I swapped out said with the Chord interconnects I had been using. I have not yet had the time(family asleep in bed when I got home) to give them full reign,but managed to listen at almost negligible volume to a green label copy of "Astral Weeks", an album I thought I knew every note and nuance of ...I was wrong! The combination or synergy(almost certainly accidental) of the Audioquest/Rega feeds revealed detail I had never heard before,or to put more succinctly ,I knew of course that many of the tracks on said album feature acoustic guitars,but I have never heard each note plucked in such startling clarity and isolation..I suppose "focus" is what I am trying to convey...what used to be "background" now in some cases has become pivotal,changing the perception of the song. Excuse the ramblings of an old man,at least this post might give you something to splutter your morning coffee/muffins or toast over!
