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?

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.

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.....

My best sound is with my Aurender's SPDIF output into my LAB 12 DAC 1's coax input.  In my set up it sounds better with the N200's clock than the DAC's internal clock in my set up.   Maybe a new USB cable rather than the fairly generic one   would equal my DH Labs coax.   Not sure.    

I had a few drinks last night and put about $700 in DH Lab cables in my shopping cart....  I didn't pull the trigger but I could use a high Quality USB and some longer RCAs
