So with the ability to use the USB-Input as an output, I really want to get a way to output the Wiim AMP to my HD650s.

I'm considering getting either a topping DX3, SMSL C-2000, Schiit Mani/Magni, or something like a K7.

Since the Wiim already has its own EQ and DAC, would that cause any issues?

Edit: Did more research - I'm gonna go for the K7. One of my use cases is to be able to use my turntable with headphones. Was gonna just Turntable -> Wiim Amp -> Headphone Amp/DAC -> Headphones, but it looks like I can bypass all of that easily by having the K7 go straight into the phono preamp and skip the DAC. That way I can use USB interface to listen to digital music (Tidal) when I want, and the TT as well.

Quick update for anyone that's in the same niche use-case of using USB DAC/AMP with the Wiim Amp to get headphones working.

I connected my Fiio K7 straight into the USB port, and the Wiim Amp had no issue recognizing it. What's really nice is that if I turn the K7 off, it automatically switches back to the speakers so I don't need to fiddle with the app - and vice-versa for turning it on.

I EQ'd my HD650s using the parametric EQ and the Oratory1990 preset I found online - sounds great.

I was even able to get my turntable to work with the headphones via the Wiim Amp directly, so that way I do have access to the EQ.
 
The limiting factor is likely to do with the amount of current the USB port can output. The support page says the non-Pro can do 650mA, so as long as that's sufficient to power the drive I don't see anything else that should be an issue. Do note that there is no need to get a super fast drive for audio duty. Any SSD is more than fast enough to stream even .wav encoded music.

Edit: According to Tom's Hardware's testing, Max power consumption by the Crucial P3 Plus was 4.17W, which at 50V is 83.4 mA. Shouldn't be a problem, as I doubt the enclosure's electronics will need more than the remaining nearly 550-ish mA to operate.

Edit: Oops, as pointed out I added an extra zero on the voltage. That does change the calculation. However, that max power state is only during file transfers. Just streaming music probably won't tax it that much. Only way to know for sure is to try it.

Hi there,

I just ordered the following NVMe SSD (2TB) and a USB case for my WiiM Amp. I read that some of you have problems with certain combinations. Do you think this combination will be compatible and will work with the WiiM Amp?

Crucial P3 Plus SSD 2TB M.2 PCIe Gen4 NVMe
ORICO M.2 NVMe SSD USB-case
Unfortunately, Crucial do not specify the power requirements (in particular the maximum current) during operation.

The WiiM Amp can provide up to 0.65 A of current. Anything above that limit will lead to potential trouble. The case does not offer to use an additional power supply.

It might work, it might just not.

Edit:
Too slow, @kyuu was faster.

But the USB port provides just 5 V, not 50 V, so 4.17 Wnwould actually require 0.836 mA. Too much to be 100% on the safe side. Now it's a question of if this max. power state is ever reached when playing music the SSD ...

They can't, really, since the m.2 drive will make up a sizeable portion of the overall current draw, and that naturally differs between models.

Though yes, they could at least state the current draw of the interface so that customers can do their own calculations.
 
Thank you guys, okay so I guess it's a bit of try and error.
I will let you know if it works.
If this combination won't work I will return it and order this one:
Samsung Portable SSD T7, 2 TB

This one should be on the "safe side", right?
 
I just got my Wiim Amp recently, still figuring it out.
My 'gut' response so far is that it's a bit overhyped, and does some very screwy things I can't replicate easily.
The software, esp with recent updates, seems still a bit lacking, but at least they ARE updating it frequently.

Your USB drive should work ok, but check into format type required on the Wiim.

I have a 1TB SD card I just started using it 'locally'.

Early results are encouraging.

So far it works (in a USB adaptor), though I had to reformat to exfat for some reason (was fat32 as shipped), though that may have been more of an issue with the Win10 NUC I'm loading tunes from.

So far I've tried mp3, flac and DSF (24/192) files ok.

It does support 'sort by' Folder (how I have my JR library arranged), so that's good.
(That is, it's native music app works well, no additional app required, at least for my purposes anyway).

It takes a LONG time to scan the drive, so not sure whether it'll be slow to respond to it when I have more files on it (tested with under 1G, so far), and how long it'll take it to scan 1TB is TBD, if at all.

Wiim seems a bit slow to respond to USB track changes, and does NOT show file extensions anywhere I can find, which is really annoying when trying to compare mp3 to flac to DSF files of same tracks. (It does display bits and rates, however).

It's a really cheap SD card, so slow response might be due to that?

My 'goal' is to use this 1TB drive as a (secondary) backup to my JRiver 'favorites' (ie, 5 star) files, and for simpler access for non-critical listening on the "TV" system (Wiim), but am having the usual 'arguments' with JRiver over how (if) to export those to USB/SD....sigh. THE most unintuitive software ever...nothing works as I expect it to.

I've had a variety of strange 'issues' with WiimAmp and Hisense TV U7 (earc), like 'remote battles' between the two remotes as to who is in control (it ramps up and down by itself!), and a few other odd behaviors I'm stilll trying to pin down to replicate...hence the 'non-gushing' review so far.

The Wiim software is, generally, pretty good, but still has oddities or lackings - hoping these will get addressed over time....the lack of file extension display is annoying.

Good luck!

To whom are you responding and what do you base your judgment on?

So far it works (in a USB adaptor), though I had to reformat to exfat for some reason (was fat32 as shipped), though that may have been more of an issue with the Win10 NUC I'm loading tunes from.
I have three different USB keys plugged into a WiiM Amp (512 GB), WiiM Amp Pro (1 TB) and WiiM Ultra (different model 512 GB). One thing they do have in common is that I did reformat all 3 of them to FAT32 using Rufus. If your SD card did not work with your WiiM Amp initially, it's definitely not because of the FAT32 filesystem. The WiiM devices can certainly deal with that, no problem. Maybe the original formatting did have other issues?

exFAT should work equally well though. I just avoid it because not all of my other devices support exFAT.

It takes a LONG time to scan the drive, so not sure whether it'll be slow to respond to it when I have more files on it (tested with under 1G, so far), and how long it'll take it to scan 1TB is TBD, if at all.
Yes, initial scanning can take some time, indeed. And even though the SoC (AmlogicA113, a A53 quad core processor) and the amount of DRAM (512 MB) and flash memory (512 MB) are identical across the trio, I always found the original WiiM Amp to be slower than the other two. Almost every firmware update and almost every update of the WiiM Home app (I can only speak for the Android version) did bring improvements in this area, though. A re-scan after new contents have been added is way faster than the first scan in any case.

Even my 1 TB USB key still has > 500 MB of free storage, admittedly.

It's a really cheap SD card, so slow response might be due to that?
Well ... yes. Might be that. :)

You might consider signing up to the WiiM forum as well. Lots of helpful and knowledable people around there. Plus myself. I haven't heard about the volume settings changing unexpectedly before, but maybe you could provide additional input there. HDMI ARC can be a beast to deal with. I tried it with my WiiM Amp and my WiiM Ultra with different TVs and I didn't have any issues. I never tried HDMI ARC with my WiiM Amp.

... the lack of file extension display is annoying.
WiiM are usually very responsive when it comes to feature requests and customer complaints. I don't see much hope for your very special request, but you never know.

The WiiM devices don't simply expose the filesystem on the USB storage device. Instead, they do run a customized instnace of the MiniDLNA media server. Media servers usually don't care about file extensions at all. Instead, they provide different views on your media files based on ID3 tags. This is the reason why you have to scan your files and have an index (stored in a SQLite database) being created at all.

The DLNA server set up by your WiiM Amp can even be used by any other DLNA compliant device on your network.
 
To whom are you responding and what do you base your judgment on?
PeterHans. Experience. Thought I'd share mine. (I have several SSD USB drives I was going to test, too, but the SD card seemed easier, and cheaper.)
If your SD card did not work with your WiiM Amp initially, it's definitely not because of the FAT32 filesystem.
No way of knowing that; could not find any documentation on formatting recommendations.
The card worked fine on W7 and W10 machines, would not recognize it on Wiim Amp.
I'll try reformating it back to FAT32 and try again, however.

I saw no performance difference between this SD/USB 'key' and other drives on both Windows machines, but could certainly be; it was offered as an evaluation copy, and seemed perfect for audio file 'subset' backups via sneakernet.

I also tested it with older smaller USB drives on Wiim, to be sure they worked similary, and the others seemed slow to me as well (initial indexing).

Next time I'll document total file size and migration times. In use for playback and selection, it seemed pretty snappy.

A re-scan after new contents have been added is way faster than the first scan in any case.
I'll check that out, Thanks!
The comment was based on a trial 2 GB trial load, of about 40 tracks, IRCC.

I am impressed with how well it displays, or finds, the album art, though that's another thing I need to test further.
If Wiim is using the tags (as I'd expected), then, since I enter most of my favorite tracks tags manually, that might explain some of the art related stuff I've seen so far (just a few hours of use so far.)
Wonder how it handles multiple image album art, or (!) pdf album notes. (I prefer to read liner notes while listening, though less easy to read on a small phone app.)
More experimenting to do on that.

Still, for non-critical listening, it's fine so far.

You might consider signing up to the WiiM forum as well.
I have used it. Not signed up yet, but will. Wiim Amp seems to have fewer threads, perhaps bc it's newer. Still looking around in there, too.

I finally turned off CEC in the Hisense U7N (2024), and that seems to have stopped the remote battling-volume control on the TV.

[Volume changes on either remote would cause the TV volume display to either slowly increase (or decrease, sometimes) and would slowly ramp to full....and back again.]

The 'ramp to full' was annoying, and dangerous....fortunately I'd had the max volume set low precisely bc of my lack of trust in the conjoined systems.
I'll capture a vid snippet of it later and send off to both vendors....assuming that turning CEC back on again will reproduce it.

It is also linked to Apple Home (ATV) which seemed to get into arguments over whether the TV is on or not, randomly turning it on occassionally (usually in the middle of the night, at loud volumes)...not certain yet, but seems that turning CEC off may have 'fixed' that too.

I don't see much hope for your very special request, but you never know.
Being able to see the file extension type doesn't strike me as being 'special' at all.

Good to know, thanks! Glad to hear it's using a SQL variant. (Retired Apps Dev PM.)

I got this amp because I wanted to test out earc/arc, as this new Hisense TV is reported to decode Atmos up to 7.1 channels on earc, and will be my first use of e-arc.
I'm considering a miniDSP FlexHTx for the big system, so this is a baby step towards learning more about what works and what doesn't before making that decision.

Anyway, many thanks for the knowlegable info; the Wiim purchase was mostly in response to Black Friday discounts, and didn't take the time to thoroughly investigate before hand.

It appears that Wiim is pretty good about documenting their features, and updates, and the software does seem well thought out and reasonably organized (actually architected, rather than just a random pile of 'wants/needs' on a list somewere that turns into a menu structure).
They certainly are far more helpful/useful than Hisense seems to be, and can't say much better about their Google TV implementation.

Used primarily as a TV amp, it's really quite nice, especially for the price, and especially now the dueling volume control seems solved.

Thanks!
 
Note for those not familiar: VFAT is the linux driver that covers FAT12, FAT16 and FAT32. EXT4 is a linux format, although I think there's a 3rd party Windows driver for it.
 
Thanks!
Interesting that exfat worked on my 1TB SD. But I'll switch it back to NTFS.
(Clearly my google-fu on the wiims site failed me.)

If it works then there's no reason to change. It just means Wiim's documentation is incomplete.

It's changing gradually. I bet that a majority of new threads created every day is concerning the latest devices (WiiM Amp, WiiM Ultra and WiiM Amp Pro) already.

Strange, but good to hear you got it sorted.

Well, with media servers it rather is "special". ;) You're not browsing a file system here, even in folder view. Hey, Windows does not display file extensions by default since 1996 ...

I got this amp because I wanted to test out earc/arc, as this new Hisense TV is reported to decode Atmos up to 7.1 channels on earc, and will be my first use of e-arc.
Caution! Make sure to enable ARC, but not eARC! WiiM devices do not support eARC. If the TV performs the decoding anyway, there's no need for eARC anyway.
 
The Hisense Giggle-TV settings for e/ARC are odd - "Sound=>eARC", but below that is "Audio Output = ARC".
Seems to work well enough.
My understanding is that eARC is backwards compatible with ARC, so the only difference should be the bit depth and rates of the audio available.
Since I'm using this primarily as TV (stereo) audio the difference is not an issue; and I can play hires material from the USB SD drive whenever I want, too.
I'm much more impressed with the software (app) for the Wiim than on the Hisense TV...though both have had updates since purchased.
