WiiM Ultra Streamer Preamp Review

But then the reclocker is doing nothing. It will only have any impact as part of the conversion to analogue.

I am currently using a WiiM Pro plus which has been fantastic, but only has optical out. The Ultra is on sale and has a USB out. I know the USB is the more "correct" way, but would it be worth going to the Ultra just for USB output?

There shouldn't be any detectable difference if you have a competent DAC.

Thanks, that was my thoughts but I just got a JDS Labs Element 4 and the OCD of feeding it optical is killing me! Sometimes just need a reality check from an outside voice

Optical is fine.
Optical can feed digital audio at way better quality than your ears are able to detect. Simply : don't worry about it. Nothing USB can offer will sound better.

Thanks, From what I understand USB uses the Dacs clock and optical uses the sources clock...either way they have to be in sync so not sure why one would be better than the other if they have to be in sync
Well in theory using the DAC clock (USB) is better since the DAC doesn't have to sync its clock to the source and jitter is lower. In practice this doesn't matter since even when using clock recovery competent dacs jitter performance is an order of magnitude or two below audibility.
USB out to the Moondrop Dawn.
This dongle dac amp contains a led that changes colour depending the sampling rate. But not with the Ultra. It stays on Red (lowest sampling rate) while my tablet turns it to blue (Tidal High Res).
Uhmm, I don't know why, but this 42 bucks 117 db Sinad ( vendor spec) thingy is an upgrade for the Ultra onboard HP amp nonetheless.

I am using the pro plus but I would imagine the Ultra would be similar. If you go in to the output settings for your device and select your current output, there should be a way to select max bits and sample rate. Also there is a toggle for "fixed" rate. Make sure your Mac sample and bit rate is 24/192 and that fixed rate is off.

Thanks for troubleshooting. I checked it but it's off for both spdif and coaxial. For USB there is no seperate section to change any setting. The Moondrop is connected to USB.

Spoke to Sipko at IOM and he can do XLR-only for 10EUR extra, or both, RCA and XLR for 35EUR extra.For a good-looking, matching Hypex companion poweramp:

He can't do Space Gray though, only Silver. My WiiM is Space Gray, so I suppose I will instead seek out Purifi options since it's not going to be proper match regardless.

Well, I'm not too bothered about it. But you mentioned usb to be the "correct" way and I thought let's test it! On the Wiim forum results are varying because of the used DACs, not all usb conections are up to date or implemented the same, and/ or the Ultra must be in fixed volume, no EQ for every bit to be extracted. The latter is a bit weird to me because that's not about the sampling rate.
Conclusion: The USB out is not a native feature of the Ultra and results might vary on the usb dac used.
