Cayin RU6: R-2R USB Dongle DAC with Head-Amp
Mar 28, 2022 at 4:37 AM Post #2,311 of 3,686
Okay. I listened with it. It sounds good. I had it on high gain and 70/100. Not much head room, but it sounded good. As I said, the Liric is lower treble light and the RU6 (and RS6) have good treble so it sounded more balanced than with my other DAPs. I have been DAP rolling with 5 DAPs to see which ones I like the most and I have pretty much decided that now. Going to keep N8ii, M9 and RS6+C9. Those 3 DAPs meet all of my use case needs.

We seem to be moving gradually to a port-less world! It just means there will be more of a play for DAPs when that happens. It would be a sad day for my RU6. Hopefully BT will be lossless by then!!!

I found this last night. Qualcomm is promising Bluetooth 5.3 this year. I was wondering why the Bluetooth dongle manufacturers have been so quite lately…

It seems Apple won’t be adopting the Qualcomm chips into their own HPs and earbuds, but I find it hard to believe Apple Music (lossless) won’t support other Bt device manufacturers… they’d lose too much business to Qobuz and the like.

I shared similar experience with this combo. I describe the RU6+Liric pairing as "reasonable but not outstanding".

If Apple didn't support LDAC which is almost free, why should we expect they'll pay Qualcomm and use their BT codec?

That's great! Please consider also version without DAP functionality (only DAC).
There are so many great R2R DAC in market. R2R DAP at good price is niche and currently we don’t have many option.

Sometimes Apple does what Apple wants, and it is not always logical! Haha!

Apple wants to sell you their AIrPods…why give you options?

Maybe it's a sign that there is a demand for such a device? For example mojo and gryphon have gained high popularity.

Yes, there are definitely, but running a business is not about taking every opporuntiy in the market. Cayin is not big enough to cover every product category that has a demand, we need to focus and remain efficient with what we are doing.

From this point onward, I shall ignor all questions or requests related to this subject. We have repeatedly explained that we are occupied by other projects, we are not going ot do this. THIS IS FINAL at this stage, there is nothing we can add in this thread on these issues.

After we heard the disappointing "portless" rumor of iPhone, Google
I read a report this morning that Apple is considering removing all ports from the iPhone 15 Pro. I had heard rumours weeks ago, but I was hoping Apple would at least, keep with their iPads and allow for the USB-C port for all Pro models, and leave Bt to the lesser models. Thankfully, that’s a ways off, and who knows where the Bt codecs will be 3 years from now…

This is disappointing.

On the other hand, we have good news from Google that Pixel 6 will support "Direct USB Access" by June and that should open the door to better DAC support.

Direct USB Access” in Android 12 is described by Google as a path to allow apps on a smartphone to directly access an external DAC (digital-to-analog converter). This, in turn, would open up support to more USB DACs as well as improving support within apps.

That is probably just a trial balloon rumor. The other part of the rumor is that the 15 won’t have a SIM slot… The EU is forcing all manufacturers to go USB-C for all wired chargers. Apple doesn’t like to be told what to do. (And they like to make money off of certified accessories). Let’s see what happens and what the market says.

I keep my phones for 6+ years. I have an iPhone 13. I will have a port for quite some time. 😉
