Are you buying interconnects for 2 channels or 7 channels (or somewhere in between)?
Why XLR? I don’t believe either the Marantz or ATI are differential balanced.
I’m a big fan of AudioQuest, However, I’m not sure I’d throw a lot of money at cables for your system. I once did that for a 5-channel dual purpose AV system. Even with a good deal on cables, the $$$ add up quickly.
CORRECTION> The amp I have is the ATI 2007 not 1807. Sorry. The 2007 says true balanced XLR. Is that not same as differential?
I was under the impression that using XLR was better regardless, providing lower noise floor etc. Not sure if the 7704 has 'true' balanced... but it does have XLR connections... Spec says balanced XLRs. Does not say true balanced on the 7704.
In short, XLR isn't necessarily better. However, the ATI 2007 is a balanced amp, and the Marantz 7704 will output a balanced signal, so in this instance, I'd be inclined to try a balanced cable.
Not to complicate matters, but you'll want to verify the pin arrangement on the ATI 2007. According to page 43 of the Marantz 7704 manual...
If the ATI 2007 is arranged with B as COLD, and C as HOT, you can always just refers (+) and (-) speaker connections to preserve polarity.
The professional balanced/XLR pin arrangement in the U.S.A. adheres to AES File 48:
Pin 1: Ground
Pin 2: Non-inverted signal
Pin 3: Inverted signal
That is how all pro equipment is wired (as well as consumer electronics designed by engineers who wish to conform to that standard, such as Atma-Sphere's Ralph Karsten, Music Reference's Roger Modjeski, and EAR-Yoshino's Tim de Paravicini), and how all pro audio cables are terminated.
In Europe, pins 2 & 3 are reversed.
Just flip the speaker cables on the amp side (+) -> (-), and (-) -> (+) and leave the speaker cables on the speaker side (+) -> (+), and (-) -> (-). You can "fix" it through XLR cable modification, but then you'd be messing with perfectly good cables, and can solve the issue in a much simpler manner.
If we weren't having this conversation, you'd probably never know the difference if you didn't flip the polarity, but since you're on AudioGon, you're probably OCD like the rest of us.
I am a bit OCD... :) esp now that I know there is difference in pin outs. Which I had not even considered would be a possibility.
I just didn’t want to mess up my gear somehow.
I didn’t think changing the pins on the cables would be that straight forward, I just ran across an article that said to change the pins.
Ok. So just so I understand:
amp end... black to red and red to black for all speakers.
speaker end... black to black and red to red for all speakers..
What effect if any will this have on sound quality and sound behavior?
Thank you for that information. So I take it for every amp that meets a US vs EU standard the global solution is to switch speaker wire connections as mentioned above... or change the pin out?
Are there any XLR cables that are built reversed so one doesn't need to switch speaker cable connections? Seems it would be an easy solution.
@lightfighter2018, if both your source and your amp conform to the AES standard, you should not have to switch your speaker cables. If either doesn’t, you won’t get the full benefit of balanced connection even if you use XLR connections. In that case, I would have cables made that do the Pin switching for you, rather than switching at the speakers. Take Five Audio in Ontario, Canada will build then for you, and their prices are reasonable.
We're mixing things up and (potentially) going to confuse the OP.
Quite simply, pins 2 and 3 are reversed on the pre-amp (w/ respect to what is normal in the US). In all reality, this should make absolutely no difference in what is "seen" by the amp, as the signal on pin 2 and 3 are, regardless of the "European method" or "USA type of PIN arrangement", a simple signal inversion IN THIS SITUATION. The suggestion to reverse the speaker cables is simply a hyper OCD suggestion (and is technically, not necessary).
OP, you'd probably be better off if you ignored this thread, plugged-in some balanced XLR cables, and enjoyed the music.
Appreciate all input. I am going to buy some XLRs and plug and play and will see how it turns out.
Although trying to sort out what is and what is not... but it occurred to me that I believe the pinouts are in fact the same. Yes opposite while looking at them on the back, but if you put the avp and amp back to back... same pin out. For some reason the orientation was messing with my head. So, apologies for not catching it sooner.
I agree with @nrenter, I would not go crazy on cables with your system. I’m also a fan of AQ cables. Solid performance and neutral sounding in my opinion. If you can get a great deal on the AQ Mackenzie cables (seems like a good price for $110), I’m sure they would work fine. Don’t over think it. Good luck!
I have seen Mogami mentioned in Audiogon before.
If I may ask -
What makes Mogami a better/same choice as other cables made by companies like:
And what would I be loosing out on by not spending more? At $40 a meter pair for the Mogami I can't imagine that not spending more won't translate into better performance.
I am okay with being wrong, but with so many on Audiogon spending thousands on ICs and PCs -- I can't imagine that any of them would replace their pricey cables for Mogami's.
Of course - if there are folks out there that have indeed replace their 'expensive' cables with cables like Mogami --
I would love to hear feedback about their experience with the Mogami gears.
