Eversolo DMP-A6 Streamer Review

[Purité Audio]

To use EQ effectively you need to acoustically measure with RE`W, which will pinpoint any issues you then use the filter parameters REW has created, and input them into the A-6.

I'm using A6 directly to AMP (Volume bypassed amp), and hence use the digital preamp/Volume control in A6.
Will an Analog preamp will be sounding better? Will an separate Analogue pre amp like topping Pre90 would be better than the built in A6 digital preamp?
What's the difference between an Analog and digital pre amp in short?
I use fully digital media for my listening.

I have this question also, please.

The only scenario in which an analog preamp can sound better is if you can currently hear hiss out of your speakers with music playing, but the hiss goes away when you plug the DMP-A6 out of the Amp.

If you can't hear hiss from your speakers at your MLP, then a separate analog preamp won't do anything.

What's the difference between an Analog and digital pre amp in short?

An analog preamp preserves SNR by attenuating both signal and noise.
A digital preamp only attenuates the signal. Noise stays constant.

‘Probably’ the best combination is variable analogue output and digital attenuation.

Thanks for the comment. No Hiss I can hear even if I put my ear closer to the speaker cone. Will stay with this setup.

Direct sweep with REW and using the filters from rew , will not work because PEQ is not available in USB inputs and no DSP available in A6. I tried this method and during verification the filters were not correctly implemented, due to the close q adjustments along with gain, Rew filters makes. It was distorting .So i made a sweep to understand the behavior, then played with the RTA to get the approximate values. Its a time consuming process.
I don't know without DSP, if we can apply filters from rew? Either i'm doing some thing wrong or we need to see if anyone else tried PEQ using REW to optimize the PEQ in their room.

Connect your laptop to the A-6 via usb, select the A6 as your default output, run REW, create filters, select XLR output on the A-6 and then ‘EQ’ and add the filters REW has created.

will give the laptop method a go, thank you

Yes i followed the same steps as you mentioned. Laptop to A6 via USB and had the sweep done. While doing the sweep itself my XLR is the output. Then created the filters and used the rew filter values and manually implemented the filter values. But didn't worked , as the sound was completely distorted.
But you cannot verify the PEQ with sweep as , PEQ only works with internal player.
So in my RTA verification after filter implementation, the plot shows some thing worst .
It didn't worked for me. May be i will see if i have saved the plot somewhere to share with you or in the near future if i find some time, will re do this and preset the plot.

You only entered negative gain filters in the low bass region?
Keith

 

[Rudguy66]

I've had mine for a few months now, and consider it a lot of bang for the buck. The internal preamp and DAC is quite good, although I am now using it as a streamer only with an outboard DAC and Preamp. Streaming peformance has been flawless using Roon with Qbuz and Tidal, plus Eversolo runs frequent firmware updates all of which have gone without a hitch.

Nice gear!

I was evaluating between this and the d90 pro topping in terms of quality the topping should be better but with eversolo I don't have to turn on the TV and the PC which in terms of energy consumption there is a lot of difference but the topping has channel balancing which you find it very rarely in DACs or streamers unfortunately.

I have been connecting the A6(ME) to my new toy Marantz AV10 with analog RCA cables. I did also try a digital coaxial cable between the two n didn’t sound good. Can anyone recommend another way of connection to improve the sound quality ?

Keith

I entered all filters including positive gain filters until 100 Hz. But I limited max gain to 3(if I remember correctly) , so not much gain in it. But I can also try implementing only negative gain filters and see if it improves.

 

[Purité Audio]

I can’t think what else would be causing the distortion, I generally only reduce ( negative gain) room derived bass peaks and leave everything else alone.
Having said that if you have speakers with a treble lift, I can perfectly understand why you want to EQ.
Keith

 

[jiji]

ok now i have only negative gain and no narrow Q. i will try to implement and verify through RTA if it works.
My room respone and PEQ to be implemented soon: (let me know if you find any issues in the PEQ implementation)
Thanks for your input keith.

J, I would start by halving REWs suggested -gain so at you 47Hz start off with say -6, then listen to lots of music that has that low bass, you can always re -adjust if there is still overhang/boom. Sometimes REWs targets are just too flat and can sound a little thin.

I find the same, somewhere between half and 2/3 of the suggested correction sounds better to me.

 

[jiji]

I implemented the PEQ yesterday night and it already sounding flat as you mentioned. I mean it in a good manner.
I will do some trial & error to have some more bass , as you suggested.
It would be great if we have PEQ activated in USB input , so that we can verify the PEQ 1-1. I requested this to mirror, but don't know if this is possible.

 

[Purité Audio]

J were you actually hearing overhang/boom/one note bass ( whatever you prefer to call it ) before you started to EQ?
Personally I prefer now to use the bare minimum of EQ, just enough to ameliorate any room mode gain, but that is with speakers that have good and even on and off axis response,
