Unbalanced to balanced VPI junction box change?


I have a VPI classic 1 with Valhalla wiring. Currently have a rca junction box and considering changing for XLR. My only reservation is needing to upgrade wiring along with the junction box. For my taste an approximate $1000.00 upgrade. I love the sound now, would be worth upgrading?

Atmasphere.....I have a totally balanced system (all Ayre components) and can readily hear the difference in cables....
Converting to balanced is a no-brainer. Easy to DIY and plenty of adapters available if you don't know which end of a soldering iron to hold.

I have a lot of respect for Ayre, but regardless if you can hear differences between the cable, some aspect of the balanced line system is not being supported and is allowing the cables to manifest some artifact.

Here are the standards:

1) pin 1 ground, pins 2 and 3 carry the signal out of phase with each other. In the US pin2 is non-inverting.

2) The signal occurs between pin 2 and 3; pin 1 is ignored and is only used for shielding.

3) The cable will have a twisted pair for the signals, within the shield.

4) the connection will be low impedance (LOMC phono is a good example- quite frequently the cartridge sees 100 ohms or less at the input of the preamp) such that the source can drive 600 ohms without loss of bandwidth.

It is items 2 and 4 where most high end audio products don't adhere to the standard. The reason this standard was created BTW was to eliminate interconnect cable interaction with the sound. Think about recordings made in the 1950s and you will see what I mean- quite often in these recordings the microphone signal had to travel up to 200 feet before it arrived at the tape recorder, yet obviously as we can hear the signal somehow arrived in good condition. This was entirely due to the use of the balanced standard.

The implication here of course is that the cost of the cable has nothing to do with how it sounds.

I have always thought that audiophiles would be interested in a means to get the interconnect cables to not 'editorialize' upon the audio signal. You would be surprised how difficult it can be to get across what the benefits are. For example the length of the cable or lack of it has no bearing in the benefits derived by being balanced.

At any rate, if you can hear differences in cables as you have mentioned, it does in fact mean that the equipment is not supporting the standard.
Standards, Schmandards, ....I'm a musician not a scientist. My system is DEAD quiet, and sounds like music....that's all I care about
That's good! Here is something to consider- if you can hear the effects of cables in your system, I would guess that you installed the cables that sounded better.

Now if you have been at this a while, you probably have replaced cables before, through a similar comparison method in your system.

What I want you to consider is that if you can hear a difference between cables, that its not a matter of one is right and the other is wrong. The fact is that both of them are wrong! How do we know this? Next year, the manufacturer of your cables will offer a newer better sounding version, or there may be an offering from another manufacturer that trumps them, or maybe a more high-buck version from the same manufacturer.

So we know that while they might sound nice, better performance is available. OTOH, if the equipment involved supported the standard, then you would not hear any differences between the cheapest cable and the most expensive. I have seen this demonstrated in spades many times.

Its not about noise, its about how the cable sounds. Again, I often get pushback on this subject but I'm not making it up- your LP or CD collection is my proof. You know how quite often audio engineers will say that cables don't make a difference? In their world (pro audio) that is the case because pro audio equipment has to support the standard and balanced cables are what they use.

IOW what we are talking about is the ability to control or 'swamp' the individual characteristics such that whatever makes it sound good or bad is no longer relevant, instead the technique is going to force the cable to do its job without editorial.

A LOMC cartridge running balanced, with a low impedance load at the preamp where the preamp ignores ground and only looks at the pins of the cartridge for the signal is the ideal situation. Although LOMC cartridges don't make much voltage, they make a surprising amount of current- not many preamps could drive 100 ohms!

So this is one area where if the preamp is set up right, the cable need not be expensive yet the cartridge can still sound its best.
