Bartok output - XLR or RCA?

Another question while waiting arrival of my new Bartok.
Mine will be used exclusively in a standalone headphone system and will not be replacing my Linn KDS in my Naim system -:slight_smile:

I want to connect my Stax electrostatic headphone amplifier to the Bartok. Are there any performance differences using the XLR output’s vs. the RCA outputs?

This one’s in our FAQs - use balanced XLR wherever possible!

Thank you for the detailed reply.
The 3rd party Stax amplifier I use (and actually all Stax amplifiers) have the capability to internally convert any signal (balanced or unbalanced) to balanced to feed the headphone. The amplifier I have (and Stax amps as well) provide both RCA and XLR inputs.

Based on what you have written it sounds like I should take advantage of the Bartok’s balanced output.
Now I need to get Chord Cable Co. to modify my Naim DIN > RCA cable to full XLR so that it can be repurposed to use between the Bartok and Stax amplifier.

Thank you for the reply

Definitely useful if your DAC doesn’t have balanced outputs, but as the Bartók has a better output stage for balanced it’s absolutely worth using XLR.

Be sure the XLR cables you end up with are standard wiring, as I know Naim use a single XLR jack for stereo unbalanced audio. You’ll need two standard XLR leads for between the Bartók and the Stax: one for the left channel and one for right.

Hello James
Actually Naim do not have the option of XLR on their preamps - all inputs/outputs are DIN with a single RCA set for those with “outlier” sources. You are most likely thinking of the XLR connection which goes in-between their power amplifiers and respective power supplies.

Understood about separate XLR cables right and left between the Stax amplifier and Bartok. I am in the States (though with a UK dealer for my Naim/Linn system) - any recommendations for XLR cables other than sourcing from the UK via Chord Cable Co?

And as an additional question - I have seen threads discussing the use of the Bartok with and without a preamp.

Are there any settings for the output or volume control I should be using when the XLR balanced out is connected to the Stsx amplifier?

I don’t have a Bartok, but I believe you want the output set at 0.0.


James, does the same suggestion to use XLR (balanced out) due to complex A-stages apply to the Rossini as well for a pre-amp or a direct-to-amp connection?

Brian …

You should run the Bartók volume control at 0.0dB and use the volume control on the Stax.

If you find that the level is too high for the Stax, you can change the Line Level setting in the Bartók from the default 6V to 0.2V, 0.6V or 2V.

Yes, it does. This is the case for every current dCS product that has a DAC (so Bartók, Rossini and Vivaldi).

You’ll get the benefit of this whether connecting to a pre-amp or direct to a power amp.
