Only audible when no music is playing at about 2 metres/6 feet. I have a recording I sent to the seller but from close up. All devices are plugged into an Audiolab DC 6 Block and I have tried different cables for both power and clock. I think you're right, in general I wont find a hard and fast...

Unfortunately firmware upgrade did not work. So in general would a high pitch noise with an external clock connected be justifiable reason for exchange, or will the the fact that it doesn't make the sound without clock be enough deniability for the store?

hahaha I'm well aware, all good I like 2nd level harmonic distortion ;). Will give the firmware update a try. Cheers

Hi Cam, no I don't, I have the one just prior. You think that could have an impact? Happy to try anything at this stage

I left the R26 with EXT clock on but no clock connected and cant hear the sound. For mine it seems to be only there when clock is turned on and plugged in. If i flip the switch off, the high pitched whine is gone even when connected

Hmm interesting I havent tried EXT Clock on with no Clock connected, will try that as well, thanks Jake

Hello all, I'm hoping someone could provide some advice regarding a minor issue Ive encountered with my R26? When the LHY OCK-1 is plugged into the R26 I hear a high pitched type of whine sound when I put my ear up to the R26. If I turn the clock off, there's still a very minor sound of a lower...

Speaking from my own personal experience, undoubtedly sound quality is usually an improvement over direct USB. On my R26 only IIS being fed by a U18 DDC can match/slightly exceed streaming (others have said LAN is best by far on the R26). Streaming convenience is obviously major as well, I've...

I got that translated and if Google is correct you asked about the IIS cable. It’s the AVplay HD-300 one from Aliexpress, I think quite a few people have mentioned it on different threads across headfi

Just wanted to post a story re the U18 and what a great device this little box is. So I took a trip to Sydney from Melbourne for the recent HiFi show and decided to take both my U18 and R26 to my friends place where we were staying for some testing fun. He has a Willsenton R8 connected to a PC...

Do not go 8A, it will offer no protection to your device. The A refers to amps or amperes and is calculated for the current coming through. When the other poster referred to size I believe they meant the size of current protection e.g. 2A or 5A. For the U18 only use the 630mA fuse and for their...

camrector, thanks for the above advice, this has possibly been one of the most frustrating firmware upgrade experiences Ive ever undertaken and your clear simple steps have finally made the text readable and I can turn off the bloody power button light. I was riding a wave of pain just like...

Thanks sajunky will do. There's a few Class A SET amps I'm looking at currently and will definitely ask the dealer to test with one. Good thing is they have quite a few tube amps on sale so shouldn't be too difficult. Unsure whether a weeks loan would viable with these guys but I still see a...

camrector, thank you so much. That's helped me understand the whole digital realm so much better. You've alleviated my concerns re the R26 and how it would handle higher bit rate files. I've organised a comparison at my local dealer between the A26 and the R26 and will definitely remember to ask...

Hello all, Its been fascinating wading through a 300+ page topic on what seems like a pretty special DAC and I was hoping someone could assist with a couple of technical(ish) questions re the R26 DAC So my understanding of r2r dacs are that bit wise they’re limited due to the technical...
