no degradation, quite the opposite. It is my finish line of wonderful performance

A little step further RU7 line Out jack 3,5mm 1,2 Volt rms Art Clean Box Pro jack 3,5mm IN Art Clean Box Pro dual XLR 3 pin OUT balanced with volume preamplification (+21 dBu) over 4 Volt rms for channel Cayin iHA-6 XLR balanced IN Sound with Monoprice AMT is my Finish Line. Stunning Sound...

Now I can listen step 2. My 2 cents: The RU7 output is 1.2 volts to contain background hiss, good. Andy thanks for this explanations. Preamp Cavalli Liquid Spark with jfet elevate to over 2 Volt rms in pre out. Good. This step is more important and necessary. iHA-6 performs its task very...

For now in SE, but I would to try 3 step: 1) balanced via 4,4 to dual XLR 3pin IN 2) with preamp in SE between RU7 and iHA-6 3) with balancer for SPL modded by me for headphone amp, with all parameter regolable (fase, vol, etc.) I think all 3 mode is different. The 3° is my personal...

A little big step: RU7 --> line out --> Cayin iHA-6 Monoprice Monolith AMT modded with 16 core balanced cable wonderful sound in High current mode Cayin, no. 1

Another fantastic setup (for me) 1More Triple Driver modified in large over ear (110mm) with 3D disc and microsuede gel pads RU7 with 3 level of volume resistor (1-49 / 50-79 / 80-100) is in 3-mode EQ equivalence: 1-49 bass like 50-79 more space for mid and high 80-100 like live event ( Pink...

Pardon, the last driver RU7 & RU6 (12.4.23) see this: it is correct ? Issue with intermittent lack of sounf with windows 10 There is a recent driver for ru7 ? I see 29.4.2021...

Planar M1060C like more than 1 Watt RMS. It is my setup: RU7 - preamp class A Liquid Spark - ibrid amp Cavalli CTH class A at 9 o'clock is very good. Usb cable ddHifi Tc09s - Moto smartphone - uapp qobuz - no other. No Optmize battery for uapp and mtp AMT drain more watt - iHA-6 soon...

Charger is connected to Hub, and charges all device Hub distribute power and data to all port usbc tablet see hub (OTG) usbc usbc converter lan gigabit use direct connetion ethernet lan (no wifi latence or interference LTE/4G) dongle is connected to hub via usbc tablet in in charging, also, see...

I would try this: RU7 --> Monolith Liquid Spark (pre-amp) --> Cavalli Tube Hybrid --> Monolith AMT Good for me. A Cayin iHA-6 is in travel... It is a third product of cayin in 1 month... love it. The first is RU6 (magic)

In this condition, the problem is the cable or the max currrent of usbc port. If 500mA shutters, if 900mA no problem. Are You have an Iphone ?

And thi is my setup: sound is superb ! :):L3000:

Yes, I confirm. I use a HUB usbc 3.2 gen2 with separate IN power PD or all type of Charger or power bank When I connect LAN usb adapter, dongle ( in this case RU7), the sound is more rich crystalline detailed and analogue. One DAC for 3, I confirm @Zap67

In teh first photo in italian "carica" = Full In the second photo in italian "in carica" = charging Also not a problem, my item is defective.

Ok good idea pernaps my DC28Cpro is defective, I'm happier that way. here is the photo with direct PD and end of charge and here is the photo with ddHifi and continuous charge, also after 5 minutes....

This is with direct charge from PD3.0 at full battery 100% and this is charge with ddHifi from PD3.0 at full battery 100% phone turned on, and only the charger connected. with and without ddhihi. Is normal ?

Ru7 is fine. Pardon mr. Andykong. I have 2 product of Cayin, RU6 and now RU7, both are wonderful dac/amp. I started my opinion with RU7 and AllToDsd i know is fine and exquisite. Can I change sound, with this option. With efficient 1More triple driver gold, 64 is (for me) the best. Thanks, love...

Ok, I specify all the tests carried out: all types of chargers (PD 3.0, QC 4.0, standard, IQ 3A) with Lenovo and Moto tablets, via usbc. The PD3.0 charger alone runs at 9 Volts and 2.2A The PD3.0 charger if you connect only the ddHifi sets 5 Volts 0 Ampere, the ddHifi forces it to 5 Volts. If...

@Polky74 Exactly. Wrong Charge - Warning see here

For Twieester6 did you check the overcharge with a usbc tester? What you say is always like this, but if the TC28CPro is involved, I guarantee you that the current is not stopped, but continues to supply current at 1.9 amps, despite the mobile phone or tablet saying "charge completed". Also...

Hi, i have my RU7 today. This dac has a unique feature, it allows you to choose the tone you prefer. AlltoDsd at 64 there is a reproductive scale of the entire sound plane with an analogical similarity to coarser steps, from light to serious. At 256 the steps become thinner to very fine, it...

I point out something that I discovered using the new ddHifi TC28CPro -usbc to usb-c OTG and power adapter. With a usbc tester I verified that if the mobile phone or tablet signal charging completed, the power supply continues to supply 5 Volt 1.9 Ampere to the host. This thing is very...

Excellent analysis, I totally agree with the idea. None of the dongles mentioned is superior or inferior to the other, each one has a point of beauty, and each one offers the musical message with something that today was forgetting: listening to music with emotion. Music is emotion, and these...

Thanks Andy for the kind replies. In the end maybe I understood why the RU6 sounds better from a pc than from a smartphone or tablet, I'll try to explain it simply: I tested a difficult pairing, Monolith AMT and RU6 in balanced mode 1 - from smartphone with usb-c 3.1 to Cayin it plays with...

A reply from Cayin about a curiosity of mine would be useful. By connecting a PD 4.0 hub that accepts data and USB 3.1 gen2 5 Volt 1A charging towards the DAC, with PD 4.0 charging towards the phone (33 watt), the dac has more dynamics, only if set to high gain. Without a PD 4.0 power supply (60...
