WiiM Ultra

Inputs:
Line, Phono, Network, Toslink, ARC, Bluetooth, USB Storage
(= 2x Analog, 5x Digital)

Outputs:
Line, Sub, Headphone, Coax, Toslink, Bluetooth, Network, USB Audio
(= 3x Analog, 5x Digital)
 
Purely as a DAC how does the Ultra compare to the RME DACs?

But I can't stop thinking that, at least, a coax spdif input more shoul be mandatory for a device described as a preamp and digital hub. Does anybody know the bluetooth codecs avalaible on the Ultra?
From the announcement on the WiiM forum it has Bluetooth 5.3. It does not support aptX or LDAC codecs. However, it does support the BT LE Audio codec LC3, in addition to SBC and AAC codecs.

Without LDAC bt is not a digital input you can use if you are seeking for audio quality reproduction

For playback from phones, it also supports Chromecast and AirPlay. For streaming, it supports almost every US service (except Apple Music) plus it supports Roon. Bluetooth LDAC would be nice, but I don't think it is a big issue given the other options.

I agree, though I’d perhaps word that just a tad differently.

Bluetooth can get you very good audio reproduction, and it’s quite likely that, by the time you’ve run out of the other 4 digital inputs, the usage for Bluetooth may well not necessitate the very purest audio reproduction.

For my needs 3 coax and 2 opgical inputs are the minimum necessary. Yes, one can add a switch box but i don’t want to increase the box count. BT is not a substitute for additional SPDIF inputs.

I feel your pain, and wouldn't seek to diminish it. But there’s not a cat in hell’s chance that WiiM, or anyone else, were ever going to put 5 x physical digital input jacks on this.

I’ve just done a very quick check on the streamers Amir has reviewed here - some costing as much as $5k - and whilst I may have missed something, I’ve yet to see any with more than ‘one of each’.

There are no low price streamers I know of that have multiple SPDF inputs. However, the Linn Akurate DSM, reviewed here, has multiple analogue and digital inputs, as does the Naim 272. Both are quite expensive, even secondhand.

I'm more interested in BT transmission so that I'm not tethered to my desk with wired headphones. I use wired headphones with a Qudelix-5K when there's noise from apartment renovations in my high-rise building, or road work outside my windows. Especially for classical music, the quality difference between BT codecs is obvious for concentrated listening. I currently use my Android phone plugged into a charger for this, but would much prefer to use my WiiM without connecting a dedicated BT transmission device.

I agree with you that LDAC support would be good. However, I think most people would pair their BT headphone to their cell phone and keep their phone in their pocket.
 
Seems like room correction can only be done with apple devices/ ios. A bit of a bummer...
Currently, you can use your iPhone's or iPad's built-in microphone.

WiiM are also looking into external microphones connected via USB to the App.

WiiM are also evaluating whether it is feasible to use the WiiM Remote's built-in mic for in-room response measurements.

I know you can do it with an iphone or ipad, but i don't want to buy one. :)

The link i posted is an example of a good, portable, not that expensive one. They could investigate that one or even partner with them or just make the app compatible with it even.

I doubt the remote's mic is better than a phone's (android). Are they actually THAT bad?
 
How good are those iPhone/iPad based room corrections compared to Auto EQ REW filters applied via PEQ of the Wiim? Can the correction be limited to an upper frequency? And can you do speaker correction with the Wiim‘s PEQ and apply room correction on top of it?

Some other speakers like Buchardt also have this App based room correction and are probably similar to what Wiim is doing.
