Somebody wake me when this ASR topic quiets down.

I was one of those that chose with his wallet…..I owned a DAVE and M-Scaler……I have no problem with people choosing whatever equipment they please….where is usual triangular dither used? In other dacs? Is Gaussian dither used only in Watts designs?Thats slightly out of context, he is refering to his design choices (qv Gausian v triangular dither) of his upscaler. Not as a comparison to other DACs. If you enjoy the Topping, good for you, you have saved a lot of money. No one is critising you for your choice. Why take offense if others choose differently?

I thought that this was the M-Scaler thread. Wouldn’t the best place to discuss the merits of the M-Scaler be the M-Scaler thread? Are you only allowed to post gushing reviews, or can you also discuss the possible negatives of the M-Scaler?Probably the best place to discuss it then is on ASR
What negatives with the M Scaler are you talking about?I thought that this was the M-Scaler thread. Wouldn’t the best place to discuss the merits of the M-Scaler be the M-Scaler thread? Are you only allowed to post gushing reviews, or can you also discuss the possible negatives of the M-Scaler?
Yes, anything under 15v should be ok.Hi guys, have some questions with regards to running the m scaler with battery packs. Wondering whether can this be done on a power supply that outputs 12v/2a? Thanks.
Is the current of 2a sufficient? As the supplied adapter is rated 15v/4a.Yes, anything under 15v should be ok.
Try it and see if it works. Since it's under the current of the stock psu, it should be safe.Is the current of 2a sufficient? As the supplied adapter is rated 15v/4a.
So you're saying Gaussian dither is actually better and you will hear better depth and detail resolution? Funny how the literature on the matter does not agree, I guess there's no Chord/Watts paper on this available for reading anywhere...?So noise is higher, but so what? You still won't hear it, but you will hear the benefits of Gaussian against the usual triangular dither. That is, you will hear better depth and detail resolution, unless you are deaf, or not blessed with good hearing, or not interested in the SQ and musical performance, in which case why on earth would you be interested in an expensive up-sampler?
Measurements did exist before: https://goldensound.audio/2022/03/14/chord-dave-measurements-with-mscaler/While I have no doubt Amir takes pleasure in revealing bad measuring gear that is expensive, I highly doubt he purposefully produces bad results. If the MScaler had better measurements, he would have reported them, while likely coming to the same conclusion (that he hears no difference). At the very least, he has produced data about the MScaler that never existed before. Owners and fans may not like what the results were, but let's face it, they showed that the MScaler has some issues. Rob Watts has already stated he's working on the next version of the product, so I hope that addresses some of the issues we now know exist with the current product.
I don't like posting there because everyone thinks they have a doctorate in audio science and almost none of them have any actual experience with the products they criticize. They worship objective measurements there, we value subjective and real experience here.
Isn't it already ascertained that it is because of the dithering, when in passthrough and 2x mode? So no, it is definitely the M-Scaler's doing.Additionally the added noise with the topping D70S seems to be being blamed on the MScaler, when in reality it would seem more appropriate to be blaming it on the DAC?

While this output might be totally attributed to the Topping's internal workings (leaving my judgment out on that one), the 96dB SINAD is a dead giveaway that it is a product of dithering, wouldn't you agree? If you measured a lot devices, chances are you've seen this kind of output before when driver or software is truncating to 16-bit? (for example, different situation obviously).I was referring to this one
Harmonic distortion goes way up (which should not be affected by digital data, the MScaler does not add harmonic distortion to the digital content) and a random spike at ~330hz shows up.
These could be jitter related (though they're high enough in level that I doubt it, again, further testing would be needed to confirm) but can't rule out a grounding related issue. As mentioned, the MScaler provides galvanic isolation so if your DAC requires a grounded source you might see funky behaviour.
Yes, 4x and up will push any problems away far enough that it's not an issue. If however this "problem" does occur in both 2x and passthrough mode as mentioned, the very least that can be said is that passthrough should not affect the digital output. It should not be doing this. I rest my case on that part, at leastIn regards to the quantization noise, as I mentioned, using it in 4X oversampling showed no concerns with quantization noise and I got significantly better attenuation than what Amir showed, both when measuring via a DAC and when looking at the digital output directly.
