WiiM Ultra Streamer Preamp Review

[gasolin75]

Hi all, considering wiim ultra vs node icon. The key difference to me is dirac vs roomfit. Setup is ascilab a6b to apollon Et6525 to either streamer to sony TV. Is roomfit good enough or is it worth it to go for node to use dirac?

Thanks everyone

Dirac live cost extra and can be from around 100 euros to over 200 euros money you can spend on music,concerts, accessories + a wiim amp,streamer is cheaper

How do you connect the PC to the Wii?
I wanted to perform measurements with REW.
I tried via HDMI without success, and also tried using a 3.5mm to RCA (line in) connector, but I couldn't get a connection..
Can anyone help?

Thanks, it didn't occur to me that it was possible via Wi-Fi. I'd prefer a wired connection, but I'll try.

From IA
Measuring with Room EQ Wizard (REW) via Wi-Fi is technically possible, but not recommended for precise acoustic measurements due to latency, potential network interruptions, and signal delays (jitter), which affect impulse response measurement. REW relies on precise time sweeps.

It seems some people recommend a USB to coaxial cable converter. I usually use 6-meter cables. It won't be easy.

Am I doing something wrong with the HDMI or 3.5mm to RCA cables? Isn't there another way?

 

[somebodyelse]

It does have wired network too. What are you doing with the HDMI? The connector on the WiiM is for ARC (port on a TV for connecting to a soundbar), not a direct connection to the computer's HDMI port. You could also use coax or optical digital if the computer has those outputs or you use an adapter. The Cubilux and HifiMe USB adapters are often mentioned, but some laptop docks and audio interfaces also have them. The line inputs should be good enough for REW use too.

Are you trying to measure the output of a wiim?
what device are you measuring with (reading back the audio)

I assume you are sending a signal for Wiim to ouptut? If so then you can't use USB from the PC. you'll need to use a Toslink or digital Coax connection. The Wiim doesn't accept USB audio from a PC. HDMI won't work, because the Wiim connector is for ARC - not for an HDMI output.

You should be able to use an analogue output (3.5mm to RCA - if the RCA input is line level (not phono). You will need to select the RCA as input in the WIIM.

Then you need to connect the output of the wiim to the input of the measuring device (ADC), or if you are measuring the in room sound -read back using a USB microphone?

Just measure it with the "from file" function,.
Generate the sweep from REW's generator (make sure you include acoustic time reference to it) , load it both to Wiim and REW and use the "from file" with acoustic time reference.

No need for connection to the Wiim, at all.

... and also tried using a 3.5mm to RCA (line in) connector, but I couldn't get a connection.

This should definitely work. I've don it before.

I seem to remember that I had to connect both channels on the WiiM side, but don't really know why.

 

[harkpabst]

It might be wise to increase the margins even more, indeed...-5db etc
I don't understand your point (perhaps due to language barriers)...
whether it's a bad practice or not... the fact is that it permeates a large part of production... and is widely recognized...
It's the fact that it doesn't seem to bother anyone that's the question...
brutal digital clipping..but generally brief
Their frequencies are simply considerable...
Sound engineers readily admit it...

I feel like I should apologize to you. After refreshing my memory of inter sample peaks I agree that 3 dB is the maximum possible "overshoot", if the recording just (unnecessarily) hits the 0 dBFS limit. Technically, this is not an indication of a faulty master (although a caring mastering engineer could well avoid this problem).

In an ideal world, a serious DAC implementation should account for this. But since that means giving up 3 dB of SNR (technically and more important in advertising), many just don't do this. Any ISP > 3 dB is the result of faulty recording/mixing/mastering. It's impossible to tell if this was done - who knows? - on purpose or (more likely) out of ignorance.

I'll try again with the 3.5mm to RCA cable

I have a Yamaha YSP6500 soundbar and a SVS subwoofer.

I use Rew to take advantage of the 3 filters available in SVS.

I recently bought a Wiim Ultra, connected to the TV via HDMI and optical to the soundbar. I wanted to compare the responses of Roomfit and Rew.

If you have the wiim connected to the ARC HDMI of the TV, and the PC going into the TV from a separate input, you should be able to get PC sound into the Wiim that way. You might need to enable ARC in the TV settings though.

'Should' being the operative word here - one of the stated reasons for the changes in eARC was to reduce the common interoperability problems with ARC. A toslink splitter might be a more reliable way to get signal from the TV to both the Ultra and the soundbar.

Optical adapter/converter/splitter will disable the CEC functions of ARC, so it will not be able to control downstream volume from the source device and it won't be able to automatically power-on/-off the downstream device.

I am currently using a Wiim amp first get with my TV in a 2.1 configuration. I am using the eq function to eq the speakers. If I were to purchase the Wiim Ultra streamer and have my subwoofer connect to it rather than my Wiim amp. Would that allow me to use the 10 bands of eq the Wiim Ultra offers to eq my sub, and the wiim amp eq function to eq the speakers or would there be overlap of the bands?

The bands are adjustable. You could theoretically use the optical output of the WiiM Ultra to feed the WiiM Amp, applying up to 10 separate bands of EQ in the WiiM Ultra to just the sub, then in the WiiM Amp apply its 10 bands solely to the speakers. The frequency of all 10 filters is adjustable. If your sub is like an SVS and has its own DSP with PEQ then you'll have an extra 3 more in the sub, too. Of course the WiiM UItra's 10 filters can be split any way you want between the speakers and the sub, in reality. Got only one big peak in bass? Use one filter for the sub and leave the other nine for the speakers, now you have 19 filters to work with for the speakers. And then the filters can be left/right separate, so now you have like 40 channel-dependent filters to work with.

Thank you, laptop HDMI > TV HDMI , TV HDMI > Wiim HDMI, Wiim optical out > soundbar optical in, worked this way.

Does the noise on the phono stages significantly affect the sound when playing vinyl?

I doubt it - it is typical of what you see on many lower cost phono preamps. It is probably also lower than the surface noise of vinyl itself.
