How to skip wiim ultra digital domain

it just shows that it significantly degrades the incoming signal...more than any other solution...that's all

That is for the Pro. A bit more noisy than a high-end ADC but still below what is audible. The Ultra using a PCM1863 has better measurements than that.

WiiM Ultra Streamer Preamp Review

This is a review and detailed measurements of the WiiM Ultra network streamer, DAC, phono stage and preamplifier. It was sent to me by the company and costs US $329. Physical attribute are modern and attractive enough. Alas, I can't say the same thing about the graphical interface. Icons seem...

@canard The sinad for the Ultra line input is 85 dB. It will not interfere with the output of a good phono amplifier, and it’s not worse than a Parks Audio Waxwing.

85* in lineinput is really weak, very weak, (and explains the very limited results in mm mc... moreover still today, since the release we do not have more information on the phono input like capacitance and impedance etc..)

It’s ok, we know @canard just likes to be the curmudgeon on the sidelines. We’re used to it ;)

""we're going to say that""""
sound cards ,15/20years before, and their ADCs, even in the general public (at like 30 dollars second-hand now) were already doing sinads at better than -98/-101db at 1k etc etc...
sorry...
;-)
but "as a supplement" it will certainly do the trick..... ;-)

Is an analogue crossover in a preamp too much to ask?o_O
Click to expand...
For $329, yes.

My Integrated Amplifier has this feature (analog bass management) but I switched to the Wiim sub out for the timing correction and flexibility and now just run the it as a basic power amplifier.

I saw an analog crossover on facebook the other day:

The SNR of my Audiolab 8000A is 80dB on line input 78dB for MM and 75dB for MC. 85dB is more than enough.

well ..
an adc stage is more or less good ... it degrades a signal more or less ..
adds background noise, distortion etc ...
it has nothing to do with the origin of the signal ...
besides for you to extract the idea of the vinyl tuner .. :
example imagine that you enter in analog a quality digital source in 48k / 24 ... here you are well below in digitalization than a 16bit enob of a cd .. etc here it is just an adc of rather disappointing quality .... that's all ...
that does not concern you, does not interest you ,does not change anything about the subject ...
besides for a relative analogy ...: it is a bit like if you said that since it is vinyl, a 128k mp3 compression would not be serious ... a degradation .. the vinyl enthusiast would be appalled ...
;-)

"so vinyl is all rotten-noisy etc so it's not serious..." is not the subject...
on the contrary... ironically we might as well not add to it in terms of degradation etc

(ps example a 15 year old e-mu sound card puts more better than 13db of sinad at 1k, with very correct entrance input, if someone wants to make digitizations at a very low price)

Hi! I am curious if one were to connect the analog out of a SACD/DVD-Audio player into the analog input of the Ultra. How would the resulting ADC sound, and what sampling rate would you select for the WiiM input for said SACD player?

How would the adc sound? I guess only you can decide, but for me it was more than adequate for my purposes.

As for sampling rate, I recall some testing someone (onlyoneme iirc?) did on that which showed 192 was worse (technically) than lower rates.
Again, without spending too much time on it I don't really reckon I could tell them apart, so went for 96, because, well, why not.
I'm assuming the main reason to go via the wiim is for eq etc, in which case that may well have more of an effect on the sound than the additional adc/dac.

SACD has a dynamic range of 105db and a frequency range of 20hz -50khz when decoded into analog, far exceeding the 85db included on the Ultra’s ADC as mentioned on this thread. So i was curious, given the limitations of the Ultra, what folks here would recommend for setting the input sample rate.

Strange, 'cos this is what wiim stated about the wiim amp.
"Regarding the analog line input, it is now converted to digital prior to being relayed to the amplifier. Thanks to our advanced ADC (Analog-to-Digital Converter), which boasts an impressive Signal-to-Noise Ratio (SNR) of approximately 110dB, the quality loss during this conversion process is kept to a bare minimum, ensuring that your audio experience remains rich and undiminished."

I don't understand how a frequency range up to 50khz (way more than 30khz over what I can hear) has a bearing on this, esp. as we're discussing analog out which will have been through a dac, presumably filtering about 20khz or so.

I was only trying to add to the analog conversation going on here, nothing more. Hypothetically speaking if one were to connect an SACD player via analog into a WiiM Ultra, what shenanigans would the ADC circuit cause, if any?

No idea!! ;)
One for the techies, or maybe I'll try it with my sacd player and ultra from a purely subjective viewpoint.
Not used my cd player for a while, but I do recall really liking its analog output.

Sounds great! Let us know your subjective findings if you get around to it.
