Thank you for the prompt response Andrew! I suspect that the Vivaldi will do a better job of oversampling. But, I thought that this function was only available with the external Upsampler?
The DAC will perform oversampling to get the bitstream up to a suitable rate prior to conversion to Ring DAC format. This is a similar process to the one performed by the Upsampler.
Give it a try both ways and choose the one you prefer.
Will do. Excited to get my new Vivaldi 
Thanks again!
I bought the TP link fiber Ethernet media converters
Around two years ago and they were eating dust because they only worked intermittently. Either they were not working properly From the get-go Or I wasn’t installing them properly. Since I got a Jcat M12 gold switch I’ve ordered a product from Hong Kong which some readers may find very interesting. The link is right below and I ordered the extreme version which is twice the price, around $1500. It should be with me in a week and I’ll share the results once I’ve done some listening
How did the Fiber Box II work for you?
Works very well, makes a distinct difference in the improvement of sound quality
