try to find parametric EQ in RS 151. Can it be setup via ROSE APP?
The RS151 model does not have a built-in EQ (Equalizer) function.
EQ features are mainly available on higher-end models (such as the RS150B or RS250), and the RS151 does not offer separate tone adjustment options.
Hi Han, sorry that make no sense. The RS151 is newer than the named modells, have better DAC more CPU more RAM.
This is what HIFI Rose claims for 151
Have a nice day
If an Mercedes S600 would not have an AC you would consider it as an high class car?
I don’t understand
Why not check the characteristics before buying?
My Rs130 doesn’t have an equalization but I knew it before

It is like the AC in S600. Nobody would expect is is not there.
Even eversolo etc cheap consumer (mostly definitly not high end) have EQ or PEQ.
I’m using RS151 just connected to my amp to follow my minimalistic aproache.
but most suprice is how HIFI Rose is answering 
Official Question to HIFI Rose:
is ther an PEQ in planing for next FW release?
Bonjour Gilles,
D’autant que je pense que l’égalisation, voir une correction acoustique de pièce, devrait plus se trouver au niveau du DAC que du streamer me semble t-il…
@domrol
please allows to translate your valuable comment 
Especially since I think that equalization, or even room acoustic correction, should be more at the DAC level than the streamer, it seems to me...
This is exactly my point. It make completly no sence to have an dac (with cpu & ram that booring all the time) and add a nother device to make PEQ and room correction.
And Yes HIFI Rose ROON have booth, but what is when listeniq to any other source?
We understand that this may raise concerns. It’s related to our policy. RS151 is our flagship model that has been optimized for the highest sound quality possible, which is a source of pride for HIFIRose. We have chosen not to apply equalizer to the RS151 to ensure that our customers receive the best possible sound quality that we prepared with the utmost care.
However, we understand that some customers may disagree with our decision, and we respect their opinions. We acknowledge that there may be some who perceive our stance as stubborn, and we empathize with their sentiment. Although we are not currently planning to add EQ, we are open to modifying our plans if many customers feel that it is necessary. It is possible that we may have made a mistake in our thinking, and we appreciate any feedback we receive from our customers.
We appreciate the sincere interest shown in HiFi Rose, and we will continue to listen carefully to our customers’ opinions.

Thank you for your answer. From a logical standpoint, your explanation doesn’t clearly show why there shouldn’t be a PEQ. In fact, it could even make your flagship product better.
But let’s move forward.
If HiFi Rose is interested in what customers think, please consider starting a poll here in the forum.
That would be a serious next step to validate this request.
Maybe I’m the only one who wants a PEQ
@ROSEHAN
Let me add one important point: nobody expects a super high-end PEQ like in expensive software or Roon. Even a basic table-style EQ with the ability to input frequency (Hz/kHz) and gain (+/-) would be a significant improvement over the current situation.
Thanks for your involvement and understanding.
While the RS520 has EQ but not PEQ… I wonder how hard it would be to add some form of room correction like Dirac or something else? Lower end units from competitors have this feature.
While you have commented on providing the best sound for your customers… keep in mind that many customers do not have well treated rooms and that having some form of room correction would be beneficial.
My vote: I respect the purest approach. If PEQ detracts from the best sound possible being achieved from the RS151 I would not want PEQ:)
I don’t want an equalizer either.

I would think EQ and room correction would best be done at the level of the preamp or receiver. Now if one is connecting the RS151 directly to a power amplifier and using the unit’s volume control I would understand the concern.

In this case take Roon or Audirvana, they include correctors
@Gillesbonatti,
but outside the Roon ecosystem, you’re essentially on your own.
If the customer decides not to go with Roon or isn’t willing to invest in additional (and possibly costly) hardware – for whatever reason – then for a flagship model like the RS151, there’s a noticeable gap.
Are you an RS151 own yourself?
@eleven, thank you for your understanding.
High-end Hi-Fi has been evolving — moving away from massive stacks of separated components toward more integrated, streamlined solutions.
While the traditional multi-box approach still has appeal from a sales perspective :), from a technical and Hi-Fi sound quality point of view, it’s no longer required.
In many cases (just my two cents), a centralized unit — when handling fully digital music (still loseless) — can achieve the same or even better results in terms of clarity and precision.
Especially when HIFI Rose has equipped the RS151 with more CPU power and RAM than the entire Apollo moon mission could have dreamed of , wich is absolutely brilliant.
