EFI｜內建光隔離乙太網路濾波器

The LHY EFI isolator has delivered the biggest improvement in sound quality in my high-end streaming system. Its natural sound, transparency, and incredible sense of space captivate me every time I listen to music through it.

It is important to give the unit plenty of space around it so that, even during continuous operation, it gets quite warm but never truly hot.

The second essential point is to use a high-quality power cable. The EFI reveals even the smallest differences between power cables with uncompromising clarity.

Overall, it has been the best investment I have made to date.

nice and a nice sound upgrade

EFI works exactly as intended and significantly lowered the noise floor when streaming music. It is the biggest improvement to date in my digital set up and is very reasonably priced. The only downside is that it gets quite hot.

Very good product. Much better soundstage when streaming music using RJ 45 8m long cable.

The background is quieter and the music is more relaxed. It is a pleasure to listen to.

I was so impressed with the EFI that I have now put in an order for the AS6 switch as well.

I think this is going to give me the cleanest internet pathway before the signal goes into the Holo Audio Red.
