This is interesting. So if I understand: you are saying that even before I get a balanced DAC (still sometime down the road), if I recable my 600 ohm DT880s (which qualify as hard to drive), I will see an actual performance improvement by comparison with the current unbalanced cabling, i.e. the recabling alone allows twice the voltage swing with the MK VI! If so, that could be an interim step...

Even with the soup cans I think It looks really good.

Cooperpwc - That's right, as long as the balanced amp does some sort of single ended to balanced conversion.

Apologies. I said "Nope" but you were apparently right. Great new pictures of the production amp here. It show a four pin jack in the front.

Which confuses me because David told me "Regarding unbalanced use, yes you will be able to use your normal (unbalanced) headphones via a normal headphone jack in the front." I have an email in to him to clarify. Perhaps it comes with an adaptor.

Man, is it a beauty. :)

it looks really nice.

but i wonder if they know that most people who are balanced use 2 3-pin XLRs. if they only offer the 4-pin jack, that will certainly affect sales.

Agreed

To me it seem as if it is possible to use 2 3-pin XLRs, but then you would have to connect them on the backside.? Or are those "out" plugs only for it to function as a pre-amp in a stereo as well?

Can someone who know the designer of this smoooooth amp contact him and ask if he could make a 2 3-pin XLRs version too, before he kills a large portion of his customer base? Cause I really want this amp,

but I only have 2 3-pin XLRs phones.

(But then againg that may be easily converted..)

i looked through the little tube chinese forum, it does not say anything about the 3pin xlr out is for headphon, but did stated that the 4pin xlr is for headphone, i assume the 2x 3pin xlr out is for preamp?
i dont undestand most balanced headphone out use 2x 3pin xlr, since balanced headphone only need 4 signal r+,r-,l+,l-, so it's logical to use 4pin xlr.
may be people use 2 x 3pin xlr can ask little dot to custom made the 3pin xlr out for their heapdhone output, i think it's doable , i seen people asked sword yang to custom amp for their headphone

it's not about being logical; it's about what the vast majority of people with balanced phones already have/use - which is, 2 3-pin XLRs. if the amp is only offered with a 4-pin jack, that would be a huge mistake on the part of little dot. that it doesn't have a SE jack too is also going to turn people off.

we'll see. still looks very interesting though.

i see your point about makig a 3 pin xlr out for the majority of balanced headphone people own,that's what made things sell. just trying to understand myself why we have the 3pin xlr out in the first place, one of the pin in the 3 pin xlr never get to use

The Dual 3 pin XLR standard began with Headroom who, I believe, built the first balanced headphone amp.

Here's my two cents about the 4-pin XLR connector that LD has apparently opted for in the MkVI. I believe the reasoning goes something like the people who already own a balanced amp (and headphones) will not be much interested in a ~$600 chinese product, so the majority of their customers will be people new to the balanced amp scene to whom the recabling cost will be the same (if not less) with the single 4-pin XLR config.

- DoA

i hope that's not their reasoning, as that would be very foolish. to increase sales of the unit it should be as widely compatible as possible. lots of people who already have single-ended amps buy little dot's current offerings to try them out and compare with their other equipment (myself included).

the only valid reasons for choosing a non-standard connection, imho, are to significantly reduce the cost of the unit or to significantly improve the sound quality.
