Question RCA interconnect

[Deleted member 201267]

Yes i did i notice more diffrence on the 7000n i Have been exploring with 2 Marantz Amps.

Can i ask what the cables were that you compared ?

Sure RCA and optical Brands Amazon basics and QED Graphite and QED speaker cables

And what differences did you hear ?

Hard too tell at this stage i think i prefer the optical i have made a lot of changes too my system recently so still exploring and expermenting .

Maybe i was unclear as i was referring to your speaker cable test.

Sorry yes that was a blind test so my friend swapped the speaker cables both QED my friends cable cost 50% more than mine.
I couldnt hear any diffrence it was fun though ! has he left the orignal cables on twice and i said 1 was better lol.
i wont say any more .🔌

That's the only valid way to judge cables 👍

CD players, Amplifiers etc too.

Still exploring those avenues ! I prefer the 7000n for music and prefer the pm6005 with my tv .

Just re-read this.

So do you know what make / model of QED speaker cable you, or your friend, owns on the grounds that you know that your friends cable cost 50% more ?

Is there not a make / model name printed on the cables ?

I applaud you for doing this, top marks hifi, well done mate

I agree its great that people post their experiences on the forum after actually testing items out...whether there experiences match mine or not.

I'm still interested to know which actual model of speaker cables were tested though !

Amazon cables are all you need. I have used QED Qunex 4S many years ago and they are a step up in build quality, but they can't and won't make any difference to sound quality. Expensive cables are not necessary.

But it is shielded, because it’s designed for industry. It looks cool, but isn’t “for Hifi”, it’s just wire.

Sorry, maybe I didn't make my point very well. I know it's shielded cable and I know it's "just wire" but the point I was trying to make is that it's not super-expensive fancypants audiophile cable "shielded by neopropypenalene as used by NASA" or whatever. It's £9/m bog standard power cable. By contrast, you can, if you like, buy Furutech DPS 4.1 mains cable at £400/m. That would probably stop the buzzing too, but the everyday cable seems to have done the job I needed it to do without re-mortgaging the house
m.d.

And there's quite a possibility that it wouldn't have stopped it👍

Agreed, not pretending to be anything. I got some from MCRU a couple of years back. Two sets of 1m with mains and IEC plugs, for £20 the lot. Too thick for easy wiring mind, which is doubtless why they sell it DIY.

I am looking at mains filters not sure if my system is going too note a diffrence or my Ears .

Why? What's wrong with your mains supply?

 

[Shrek]

not tried Coaxial Yet ! have any of you ?

I use coaxial from my PC to CDP.

Why do you do that ?

 

[WayneKerr]

Why do you do that ?

PC has a digital out in the form of SPDIF coax, CDP has 2x digital in - SPDIF and TOSLINK. Local FLAC files are stored on my PC - ripped CD files.

I can connect by optical or coax from streamer to amp.
No difference in sound, but the galvanic isolation makes optical essential in my case.

A mains filter can remove a DC offset, which may make a transformer inside an amp, or other box, buzz. A faint buzzing, audible from a few inches away, is nothing to worry about though.

People refer to a mains filter producing a clean mains supply, and obviously clean is better than dirty, ewwww, not nice. As far as I am aware a mains filter is not needed, unless you have a DC offset. As an aside, it might make sense to use an extension lead with a surge protector.

Sounds interesting! Completely over my head though
