Metrum octave or Wyred 4 sound coax vs usb


hi my friends.
you very help me with what to buy i think i go with Wyerd 4 sound, in my country i have option to buy W4S-dac1 in budget of 1000$ instead of 1500$ price (bcz is it israel is very expensive country lol).
but on the other hand i get recommendation from here in audiogon on the dac of metrum octave that sounded very good with kind of my speakers (devore nines) and leben (amp) someone here work with metrum octave mini nos dac with similar components system to mine (shindo and nines).
but i read that metrum dac need very good usb to spdif convert like audiophilo that coast 1000$ so i like to know
if i dont use convert usb to spdif and connected pc-->coax-->metrum dac .is it sound better then wyred 4 sound dac1 or not. or i must use spdif to usb convert to enjoy the metrum octave dac (and is it must be expensive usb spdif convert like audiophilo)?
sorry if im not understood in simple words what will be good buy for me : Wyred 4 Sound dac1 in my country 1000$, or to buy Metrum octave mini nos dac from audiogon in 1000$ + OR NOT with usb to spdif convert ???

please i wanna know what to buy .:-)

I've used the Audiophilleo 2 + PurePower on a couple of DACs (Anedio D1 and D2, Neko, Burson, PS Audio DL3) and it's been a major improvement in sound quality. I reckon both the Metrum and W4S would benefit from it. I haven't heard the Octave but over on headfi someone sold their Octave for a Neko and I'm very happy with it as well.
