Is a femto clock important if you aren't using asynch USB?

I am considering buying a used Wyred 4 Sound DAC2 DSD se for streaming from my Bluesound Node 2i, and the seller told me that this DAC2 se is one of the early ones that does NOT have a femto clock.  My Bluesound does not have USB output, so I won't be using the USB input on the DAC2.  My understanding is that the femto clock is mainly useful to sync up the digital stream from a computer; is it likely to make much difference if my source is a streamer and the input is SPDIF?

Topping D90 ($900) is a better choice than the W4S.

While it is true that USB does not rely upon the streamers clock, it seems to me that you want a good DAC clock for stable sampling of any input.

Seems?

What you really should want is a modern DAC instead of worrying about clocks.

I like buying used but never do it with Digital gear.    I did buy a R2R DAC ,  but I also have a DAC that can do DSD.     When I bought my streamer I wanted the latest tech and codecs.     I am a late adopter when it comes to everything else.....

Some DACs like my RME adi2 always use their internal clock regardless of input type.   It's Femto clock is used also when there is a Coax or Tos. Input,  it doesn't just use it's clock for USB.
