Wow you are the one who designed these magic. I love them so much! Thank you for the amazing products. Also thank you for sharing the thread to fix the power issue. It was packed with much info so I will have to go through it slowly.

There are differences that seem to be really small at first but once you are aware of them suddenly become so obvious. Because of this people argue all the time trying to quantify them as 2-3% or 20-30% difference. I don't think you need to have trained ears or graph to see the difference...

Absolutely. My Zen DAC V2 + Zen CAN + HD660S OG + XBass ON = audio heaven. I can use the quarter inch jack with no issues, but most of my other sources use BAL 4.4mm so having to switch the cables all the time is pretty annoying. Yes that sounds like you are having the same issue. That sounds...

I'm facing a very weird issue with the 4.4 balanced output on my Zen CAN. My HD650 with a copper 4.4mm cable make distorted noises & cracking sounds & random hiccups after turning louder than about 11 o'clock. Is this clipping? The cable works fine on my micro iDSD signature, Cayin C9, or even...

Do you have some dongles to recommend with good LO (i.e. correct voltage)? I'm looking for a good one to use with my C9. Thank you.

I found it. It turned out that I saw the review under ER4XR instead of ER3XR. May be this is only true for Amazon Singapore. https://www.amazon.sg/product-reviews/B01GW786B4/ref=acr_dp_hist_1?ie=UTF8&filterByStar=one_star&reviewerType=all_reviews#reviews-filter-bar

I read that a few days ago in Amazon's review section. Someone claimed warranty with Etymotic and was rejected because they made the purchase on Amazon. I'm trying to find the comment again and couldn't find it yet. That's strange.

I bought a set of ER3XR from Amazon last week and it was broken straight out of the box. I found another person who had the same issue in another thread here. Amazon sent me a replacement immediately. But now I also learned that Amazon is not an authorized dealer of Etymotic and I may get into...

I love your impressions but I love your conclusion even more! :L3000: Thanks for sharing.

Update: Amazon sent me a new set of ER3XR and so far it's OK. I will test this extensively for the next 2 weeks and hope that this set will last. I'm a bit nervous now.

That is sad. I hope they help you to resolve the issue asap :(

Could you reach them on the phone or drop by their show room at The Adelphi?

It's noted in the RU7 thread that it's a shared LO (similar to a maxed volume output used as LO) and some people pointed that S2 has an LO so I'm checking it out. This is nice. I'll look around to demo an S1 or S2 with the C9. Thanks for sharing.

I came to ask the same question. I'm looking for a dongle with Line Out to simplify my Cayin C9 setup and make it more portable.

The new Cayin RU7 is very interesting: 1-Bit DAC sound & a (shared) Line Out. Is there any other dongle on the market right now with a Line Out?
