Cannot connect to AK DAP My Pi7 cannot connect to the AK SP2000. Believe others have faced similar issues connecting to AK DAP. Has approached the local agent and their reply is that B+W are not responding to their queries regarding this issue. This review...

How do I know if I am clipping the HA-300? I read that the ideal speakers for the 300b amplifiers are the high sensitivity (preferably high 90s?) and/or flat high impedance ones (I see that HA-300 manual states 4-8 ohms). However I am using a pair of Spendor Classic 3/1 (rated 88 sensitivity, 8...

Thank you all for the advises, really appreciate it. As for tube rolling, has been reading through this forum and probably looking at Psvane CV181 TII and Acme 300b. I am more into Jazz and Classical, and looking for details, holographic soundstaging with proper instrument placing, airiness...

Yes, I will be getting replacement for the Shuguang WE6SN7 tubes

New HA-300 fuse blown 3 times Just got my HA-300 and it was dead on arrival; the set can be turned on with tubes lighting up but there is no sound. Was advised by the dealer to change the fuse (160ma) inside the power supply; and then all seems fine. Then next day, the same fuse blew again...

I seem to have the same problem but left driver. Driver does not play music until I crank up the volume and after that it plays fine. Encountered this on both HPA4 and WA22. Plan to swap cable sides to see if it is cable issue but the problem this is intermittent and not sure how long I need to...

I got hold of a Chord Hugo 2 as the source. On lineout, the crackling is terrible. Had to reduce the volume on the Hugo and crank up Jot R. With this, the crackling does decrease significantly but still there occasionally depends on the track. i am curious if this is the nature of the SR1a (ie...

Thank you for the advise. Yes, I do observe that the crackling stops when I turn down the volume of the DAP. However, the volume sounds quite low; probably my hearing is bad :). I then had to turn up the volume knob of the Jotunheim R but I realise the volume does not actually increase anymore...

Just a few examples but I get crackling for many more other tracks : - Beethoven Piano Concerto No 5, Boston Symphonly Orchestra, Seiji Ozawa, Telarc : very bad starting from the 1st note. - Holst Planets, Sir Adrian Boult, London Phiharmonic Orchestra, EMI : occasionally - Karajan Gold...

I just got the SR1a and the Jotunheim R. Am using the SP2000 as the source; lineout at 2v. With the Jotunheim R volume knob at about 12 o’clock and above (which to me is not particular loud actually), I tend to get crackling distortion noise on SR1a on quite a number of tracks, I listen mostly...

I think I have found the problem. I had problems with my music files recently and I copied the music files from my Aurender X100 to my PC . It seems that Aurender creates a hidden .aurender folder in each album folder, containing the thumbnails eg. album cover. As these were hidden, I did not...

Yes, I did a factory data reset. And it did not solve the problem.

Yes, I am copying to the Music folder in the internal memory. Each folder I selected is probably about 2GB. Not sure if there is a problem with this set?

Cannot copy folder to SP2000 : I just got the SP2K SS. When I tried to copy a folder (of music files comprising of Flac and DSD) to its internal memory via a PC on Windows 10, only the folder is created in SP2K but no music files are being copied across. There is no popup windows with the bar...

I just received the U16. Source is the Aurender X100 and DAC is the Denafrips Terminator. I am having issue with clicks and pops. It is really bad (not intermittent) with files of 96khz rate and above. 44.1khz and DSD seem fine. - tried different firmware : same issue - tried both HDMI I2S...

Fading in at start of track..... My source is the AK240 connected to the Mojo via optical. I observe that there is a fading in effect at the start of a track. Is this normal? My Ak240 gapless is off. Thank you for your advise

Just tried using another phone, a Samsung running on Android ver 4. Using Onkyo HF and OTG cable, still cannot detect CDM. Could detect the Hugo though. Not sure if the issue is the CDM.

Got an OTG cable. Still not able to detect CDM.. Hugo plays fine with the same setup.

Thank you all for the advises. Will get an OTG cable. However, I am curious why the same micro-micro USB cable works with the Chord Hugo, and my Android phone is able to detect it as an USB device?

Hi,   I just purchased the CDM and it does sound very very good.   The issue I am having is that my Android phone (LG G3) is not able to detect the CDM.  LG G3 on Android Ver. 5 running Onkyo HF player; micro-micro USB cable to the CDM.  Using the same phone and USB cable to the Chord Hugo...

Hifiman responded and offered exchange without questions. So all is good.

Thank you all for the advise. Retailer is sorting this out with Hifiman. Will update once I hear anything.

More of loose metal sound, as though the diaphragm is flapping type of noise.

Got the He1000 a few days ago, and found something strange. If I slap (lightly) the 2 sides against each other (ie. against their earpads), there is a rattling noise on the right side as though something is loose within tthe transducer housing/earcup. Left side does not have such rattling...
