Cheers for the response!

yes, the 4 pin is more practical:biggrin:

but with the 3 pin you can choose more expensive connectors:biggrin:

Ah well not an major difference to the sound than I guess smily_headphones1.gif

none with the same quality of connector(in this case neutrik)

Actually don't the dual 3pins have grounds and the 4 pin does not? Although there could be a ground worked into the design of a 4pin amp

no. in the dual 3 pin you have two wires for each connector(+ and -)

in every case, the 4 pin has one pin for the ground in the upper side

I am very impressed Aldo!

Here is a picture of my LD VI+ before I molded it and replaced the fans.

You would notice that on the 3-pin XLR inputs there are actually four connections. The 3-pin XLR also have a chassis tab which is also connected to the metal outer part of the xlr on the outside. If you look closely there is a jumper wire connecting pin1 (cable shield) to the XLR chassis tab. This might  mean that the chassis ground and the AC ground are at the same potential as it should be. The next time I take my LD apart when I feel the need to do that I will confirm that.  Normally pin 1 is not used in a balanced inputs but since there is single ended inputs available on the amp as shown on the far left of the picture with the yellow, blue and black wires. You have to have a common ground in order for the single ended inputs to work. If someone is using a RCA to XLR cable converter on the inputs you would then have to use pin 1  as a common ground in order for this to work. If someone is just using balanced source XLR inputs just pin 2 and pin 3 are used.   Since LD is using shield cables from the inputs to the four ganged volume pot on the front the cable shield had to be connected to ground to help with induced noise issues. In the middle of the picture with the little red circle on the right is the ¼ jack output. According to the LD manual the front 4-pin XLR it said this:

1.L+

2.L-

3.R+

4.R-

Note: None of the pins should be connected to the shield/sleeve/chassis ground as the Little Dot MK VI+

does not support this type of grounding. Please make sure you or your cable builder knows this as

otherwise you may have noise issues and/or other misbehavior!

 

I noticed and others have stated that the 4-pin XLR output on the LD is stronger than using the ¼ jack at the back. I have headphones that can be used as balanced or single ended and this seems to be the case.

Finally got my Little dot MKVIII

 

Getting back my reterminated (Balanced) HD800 cables this afternoon.

 

Should be good!

when i used my headphones rewired with moonaudio(black or blue dragon), this cable has 4 wires more one ground.

i tried with only the 4 wires and 4 wires more the ground soldered in the 5th pin of the 4pin neutrik.

no problem at all because the headphones don´t have the ground.

the only headphone(that i know) that has the gorund soldered in the driver is the beyer T1

That's good to know about the T1

Your knowledge in electronics.

 

I think you had a good teacher, better than mine..............:evil:

 

John I have noticed the same between XLR and 1/4" outputs in other amps.

Yes and not always. The Woo WA22 and possibility the Cavalli Liquid Glass the 1/4 and the XLR are some of the exceptions power wise.
