WiiM Vibelink Amp

[Mr Ee]

If you really want to connect three different sources with three different subwoofer outputs to one Vibelink Amp.

I think I've said it before, it's a power amp that happens to offer alternative inputs and gain adjustment. It's not an integrated amplifier.

I think perhaps you misunderstood my comment?
Setting the volume to max, "eliminating the need to adjust it on the amplifier", surely only works if all inputs in use have their own volume control in their source.
Doesn't have to be an ultra with sub feeding it. Maybe line in, not undergoing adc, is vinyl, for the purists.
So while it can be effectively used as a power amp (as can any other integrated amp), to me that only seems to make sense if, for example, an ultra controls all input to it and a single input is used.

the Bristol show where he was supposed to be presented has passed (end of February).... somes precises informations etc returned which would avoid all these suppositions continuing etc...etc....etc?

I hope I did not.

Absolutely. @WiiM Support didn't suggest to always set the vol to max and forget about it. Their answer was explicitly to this post:

Adding a subwoofer output would duplicate even more of the features of the WiiM Ultra. Some are complaining about the digital inputs and the volume control on the Vibelink Amp, already.

There's no one size fits all. The Vibelink already tries to be a compromise, instead of bringing a pure power amp and a non-streaming integrated amp to the market. Many ways to skin the cat, but it must die, one way or the other.

If you use the subwoofer output of the Ultra then you should use a power amplifier, because if the volume control is on the amplifier side, the sub output level...

So, we all agree, I think. With the volume control set to the maximum position the Vibelink Amp simply works as a power amplifier.

The real question is how are digital and analog inputs handled?...
there is no reason why wiim support-team etc should not explain it here... especially if it was presented etc, their silence here is let's say... surprising...
(and the techno of the amp part of course...? for the sake of awareness)

No, it’s not surprising at all. WiiM’s forum team here rarely reveal too much about a new product’s spec before the official press release.

the machine seems to have been presented (Bristol ? ) .. and these few modest questions really do not deserve such silence ...

well, there are many more important subjects where we would often like to have enlightened interlocutors with whom to dialogue ...



here, it's just a game of teasing "in the air of time"

Perhaps the silence indicates that the previewed product was not final production and that they may still be implementing changes based on feedback to said preproduction unit.

Well they still haven't told us the input resistance and capacitance of the Ultra Phono input

 

[RVG]

Was told, one of the biggest pleasures when running WiiMs is poking in the fog after WiiM or users spreading teasers or rumors. Seems to be true ;-)

Loss of quality how?

Your analog signal will pass through a secondary preamplifier stage (Vibelink) before reaching the amplifier stage, each preamplifier stage has its signal distortion.

 

[Steve Woodhouse]

Often, once turned to full, that’s removed.

The measurements will tell us if any distortion is introduced.

Try telling that to the uber-subjectivists.

My thoughts/worries as well.. maybe with the volume knob in the maximum position, it could bypass the preamp circuitry? Some kind of switch?

Is a buffer a preamplifier?

Well they still haven't told us the input resistance and capacitance of the Ultra Phono input

To be honest, I never took the time asking support for specifically that. I probably should.

probably this button is just a voltage control for the amp...

 

[harkpabst]

Is that in response to "buffer" or "asking support"? I'm confused.

 

[canard]

no no...
just a general reflection, dialogue...
reaction to what seems to me to be a confusion very probably on the role-nature of this potentiometer..not to you

 

[KeithM]

There is a review at: Wiim Vibelink Review

 

[pieterv1]

So we got a ASR review before an official announcement or spec sheet... Now it's getting silly with the teasing

 

[canard]

if now presented like this..
(in any case the product was well finalized... and already well presented)

the wiim teams will finally be able to clarify certain points here...
processing of the analog input (adc?)...
the type of internal dac... ?
the use of the potentiometer? etc.
based on amp pro "simplified" ?

(the rest is a product, which has become quite typical, in 3255 pffb increased in power (tension), compared to the amp pro..which was expected...)
