SMSL SU-X with 2x ES9039MSPRO

[Panelhead]

Hi Smarty,
What preamplifier do you use with your SU-X?
I'd like to use this DAC with my floor-standing speakers and home amplifier (Anthem Statement P-5 multi-channel) and I don't know whether I need a preamplifier or not. Is it necessary to use a preamplifier in my situation and set the SU-X volume to FIX or can I use the SU-X with my system and just use the DAC volume?

If all your sources are digital you can use it as your very low noise and distortion preamp. If you have a sources that output analog, no.
I tried my dac today as a preamp into an integrated amp. Set gain on integrated to unity and ran balanced output of dac to sub, rca into integrated.
Definitely tighter bass response. More extension too. But when the integrated was turned off the sub kept playing. Had to mute the dac.
After five hours decided the added extension on bottom was scary, too much really low output. Think the integrated amplifier sub out may have built in sub sonic filter.
Hooked it back to where dac is a source playing into an integrated amp and the sub out from amp is driving the sub.

I use a Mac Mini as the source only and no other sources. Hopefully it’ll work

It will be fantastic.

Rather amusing and very honest review of the smsl su-x below, the reviewer is known for accurate no audiophile bullshit nonsense reviews using level matching etc etc. He often quotes ASR/Amir in his reviews as being one of the few websites with a very thorough testing process

I've had one piece this for two days now, and I'm more than satisfied. For me "definitely SU-X is not sux .
