WiiM Amp Ultra

[Burnside]

I know I will be shot down here, but I have been using my headphones on the Amp Ultra, connected to the USB using a UGREEN USB to 3.5mm Jack audio adapter external sound card USB DAC, which cost me £9.99 on Amazon. As I live in a flat, this is great for late-night listening to music and films. Maybe it's me, but the above picture never made me feel that you could connect a turntable or headphones as simply as on the Ultra.

No reason to get shot down - people were confused as to why some WiiM devices had USB audio output, particularly the amps, but connecting headphones was the obvious use case.

Does anyone have detailed specs on the power supply in Amp Ultra?

No, don’t think I’ve seen such anywhere.

 

[GavriloD]

No, don’t think I’ve seen such anywhere.

That is a bit strange, don't you think?

Which part of the spec are you interested in? Some members here have probably performed tests on the Amplifier so some info might be in those threads.

 

[Burnside]

That is a bit strange, don't you think?

Personally no. I’m more interested in how it sounds overall, which is very good in my opinion. What aspects of the power supply specs interest you?

Is this going somewhere?

I love this little unit. I very much like Wiim products and their software is amazing.
I had a pair of old Dynaudio Contour speakers and wanted to build something around them, nothing pretentious, simply something I can have playing music I like most of the day.

I bought Wiim Mini, put it together with Fosi ZD3 and V3 monos. Mostly what I need is streaming, some CDs that I rip to FLAC and listen to from my computer. No TV or anything else, no headphones, no vinyl.

Amp Ultra is actually a perfect device for me, same amp as V3, same DAC as ZD3, streamer included. It actually lets me have an optical in open if I want a cd transport. Has sub out if I ever decide to go that way. The only thing that concerns me is the power supply. I am strongly considering exchanging what I have for Amp Ultra.

Why does the power supply concern you and what do you want to know about it?

 

[GavriloD]

I want to know the voltage and amperage range of the power supply so I can understand if the amp implementation can handle my speakers.

Perhaps this is good enough for you but not for me I want numbers.

Better ask WiiM then

The only people who can give you this information are WiiM themselves.

This page says the same thing. For comparison the minimum speaker impedance for the Amp and Amp Pro is 2.67 Ohm.

What is so special about your speakers that you think that the WiiM Amp Ultra won't be able to handle, and which model are your speakers?

He said his “non pretentious” Dynaudio Contour speakers worked well with his fosi v3 monos. Not sure why he feels the amp ultra won’t be sufficient. Who knows what the OP getting at.

I am not sure why some of you are getting your panties in a bunch, it is a perfectly reasonable question, and I see no reason it has to be asked and was not posted by Wiim with other specs.
What are amperage and voltage TPA3255s operate at?
Why do I even have to ask this and get all sorts of silly responses?

Have you asked WiiM, as they are the only ones who can give you this information.

Do you know what the minimum impedance of your speakers is?
