… and, according to their website, they have a couple of distributors around the world. Even in a sort of ”under-developed“ HiFi country like Germany.

Where does one acquire a replacement adhesive magnet disc? I had two that came with my orange RU6 case and put one on my iPad and one on my iPhone. Inserting and removing my phone from its case wore the leatherette off of the magnet.

I really love the sound of the RU2 RU6. So much so that I purchased an RS6. However, I find that I don't use at all these days. I need to be able to control the volume from the source. That doesn't mean it's a bad product by any stretch; just not suitable for my specific use case.

I'm going to sell it with an unused blue case for 220USD (including shipping to cont. US). It is in excellent condition. Unfortunately I'm not able to find the original USB C>A adapter so I'm including the one from my LP W2.

If you're interested in a much loved, but little used RU2 RU6, shoot me a pm.


[edit: corrected model number]

out of the 100+ dongles andy has rated, the RU6 is #2 overall. the W2 is not even in the top 10.
I have both the W2-131 and RU6 here and both are great. There's a difference in their sound, obviously, but I wouldn't describe the differences so dramatically. I suppose that the R2R NOS sound was more of a big deal for him than it is others.

out of all the dongles i would buy, the OG W2 would be the other one i would check out. i would still like to hear one and compare to the RU6.

The dreaded EMI noise problem is still not solved even with my new FiiO shielded cable. It is less prominent though. But when carrying the RU6 and my phone in the same pocket, it will inevitably happen.

The RU6 shielding if it exists at all is really really bad.

This is still one of the best sounding dongle DACs in the World but if I had to review it now, I would give it 4 stars out of 5, because it cannot be used as intended with a phone on the go.

I will still try to get the leather case and DIY a shielding layer with aluminum foil inside of it, but there is no guarantee it will work

Have you tried using some other phone with the RU6? If you still get EMI then maybe you have a faulty unit. I've experienced severe EMI with EarMen Sparrow and to some extent with Mojo but not with RU6. I'm using stock USB Cable with mine.

I just ordered an RU6. I am hoping the lightning cable holds up.
