RME DPS-2 Linear Power Supply

[Davide]

But if they committed themselves to lowering prices of their interfaces instead of making these apparently useless kind of products, would they not earn more consumer markets? (see Motu price/performance/function ratio)
Because if that's not the goal then I really miss what it is...
I also experimented with the power supply of the converters and under certain levels everything is practically insignificant for audio.

What is expected of all owners of systems with all-in-one monitors (Genelec, Neumann, etc.) is a digital preamp (with all possible digital inputs and outputs) without a DA converter and without headphone output. But with an AD converter, equalization, loudness and RME quality. And why not a streamer. A bit like MiniDSP's SHD Studio.

I can’t decide whether Linear or μFilter sounds better
 Unfortunately we cannot help you there.
---RME write fun and honest manuals.

I purchased this unit and it's arriving in 2 days. Does anyone here own this power supply? I read the manual the differences btwn the Linear and the uFilter. I'm just assuming that RME designed this for a reason? Specs are different. Even if the sound is the same, from an engineering perspective or ASR common sense, which connection would be favorable for use with the ADI-2/4? If nothing else, this PS should help keep me warm in my office this winter

Discussed and measured that there is no audible difference, whatever suitable power supply may in use.

Why did you buy it?

I know any "power supply" units are deemed as unnecessary and a waste of money here on ASR. But I really just wanted to try out this unit. I think RME produces great products at fairly reasonable prices, and it was much less expensive than the fancy power cord I was eyeing haha. Would you think there would be any difference with the linear filter vs the proprietary RME filter on the DPS-2? I can accept "no difference" as the answer.

No difference. For any of these power supplies and/or filters.
Unless you have an exceptional problem. Which is extremely unlikely in most cases, especially for simple home use. Which is why I asked.

The RME devices measure 100% audibly perfect with the stock power supply. Even if (and it is incredibly unlikely) one of these fancy PSUs/filters made a measurable difference - it can't make it sound better than perfect.

"No difference" is your answer.

Thanks for you honest reply. Appreciate it. But is anything 100% audibly perfect?? Happy weekend everyone!! Still hoping that someone (anyone literally) has purchased the DPS-2 and doesn't feel like it was just a waste of money.

This thread may help, but this post in particular shows some actual data.

There is only noise, distortion and frequency response as far as audibly relevant imperfections in DACs are concerned. Humans ears have neither infinite resolution, nor infinite bandwidth.

The majority modern dacs have distortion and noise lower than any human is able to hear, and have ruler flat frequency response out beyond the frequency range any human can hear.

So yes - the majority of modern dacs are audibly perfect, including many at the low priced end of the market. In that their imperfections are not audible.

It is never a waste of money when it supplies a honestly placed member in 'no f@ck you'.
Had in mind for myself to buy things like this from RME just to support them, as they do a very good job, worldwide.

The DPS-2 has two outputs, and its μFilter output is identical in performance to the LNI-2.

The distinction is measurably vs. audibly.
Can humans hear -119dB vs. -120dB SINAD all other things being equal? No.
Can we measure that difference? Yes.
That's why it is considered audibly 100% transparent. Even though we can clearly measure differences in performance compared to other DACs.

At the level of RME, the measurable differences are down to ground. Solar activity. etc. To get a feel for -120dB, perhaps see this:

The Shoutometer

We've all seen the Sound Pressure Level decibel reference tables where you have "quiet room", "chainsaw", "jet engine" and so on. While that is handy for estimating increased loudness in decibles, it didn't help me when thinking about the measurement levels obtained around here when measuring...

www.audiosciencereview.com

The threshold of human hearing is such that -120dB is as audible as someone shouting from kilometers away, so -119dB is 100% inaudibly different. The nature of the shout matters... are they shouting noise? harmonics? which harmonics? and at what frequencies? I hope you get the idea.

I own RME, but have other items from them and others on my wish list. I don't suffer from any problems with power and ground so it's not just not compelling. If I did, I would figure out what is wrong with ground and/or incoming power. The DPS-2 would be last resort.

I love gear. And it seemed a bit odd to me to replace so many pieces of gear with just the ADI-2/4. Almost feel guilty. And in the past I've spent far more on power supplies and line conditioners compared to the DPS-2.

I'm embarrassed to say that I've spent far more on power cables and interconnects.

So I have no regrets and I am happy to support RME. In the long run they're saving me a lot of money!!

Hi, if there is a line of audio units on the market that DO NOT NEED a linear power supply it is the the RME products. Invite your wife for a nice dinner instead!

 

[johny_2000]

Invite your wife for a nice dinner instead!

I appreciate your sense of humor! My wife is happy too, besides all my big boy toys .
Another one ($$$$) is on the way, and its measurements and listening will be published here. See my posts.

Congratulations! Beat wishes and a good health to latest son when he decides to join this world. Serious potential to become an audiophile as the father already has one of the best DACs there is (or is it 'there are'). Have a nice Sunday.
