Nobsound Elfidelity AXF-100 USB Power Source HiFi Interface Preamp Internal Filter For USB Audio Device DAC
Took 2 weeks, shipping 20 days, in general, a little more than a month. Seller competent, read can even respond. A full set of, goods, packaging not very, but does not hurt. The Difference in sound I didn't notice. They say you need to warm up the plan to hold in the sound may change.
I bought this card together with elfidelity power filter card and a fanless Seasonic X PSU. Installed all three and after only 20hrs of burn-in the improvement in sound quality is obvious. The sound is much smoother, better separation, details, bass... And it'll get better after 100+hrs! Highly recommended upgrade to your pc-based system.
Was intact, complete set.
