When I try to log in to Tidal on my AK70 Mk II, there is an error message saying "Authentication Failed - Unknown error." I think I might need to install a newer version of Tidal on my player but I don't know how. I found a youtube video of a guy installing Tidal on another Astell Kern player...

Hello, I am using Amazon HD music for streaming on my SP2000. A few days ago, I started to get an error message: "Content Not Found .... You may not be eligible to access this content." I have a paid subscription to the HD service so I don't know what is going on. Has anybody else had trouble...

I went to the APKPure website to try to download Spotify and install it on my SP2000. The website does not show an icon to download an XAPK version of Spotify. What it shows is an ability to download it using Google Play. I don't have a Google account and I'm not trying to install Spotify on an...

I'm considering the Kann Cube and the SP1000. I'm not sure I really need the extra power in the Kann, but it is tempting if I ever purchase a high-end power hungry headphone. The price is basically half of the SP1000. I'm wondering if I would be sacrificing higher audio quality by choosing...

Thanks for the info on the bass. Honestly, I think the main thing I'm looking for is a really good snug fit. Might sound weird, but my favorite IEM's of the past were the one's that I felt I could really lodge deeply into my ear canal. Getting that kind of seal makes the sound so much better...

I am also interested in the Spinfits. Their website has 2 sizes, small bore and large bore. I assume the small bore is the one that fits. Are they only available from Singapore? I am using the supplied compy foam tips (which I assume are medium) but the bass isn't very good ... I'm thinking...

When I stream Sirius XM audio over my iPhone to my wireless Beats Solo headphones, the volume is good but not great.  Is there any way to insert a portable headphone into the setup and still have a bluetooth connection for the headphones?

So I bought these wireless Beats Solo 2 (over the ear) headphones for the gym.  I am playing most songs using the Sirius/XM app on my iPhone 6.  The volume is not really loud enough for the noisy gym for me.  I have a few portable amps (Pico, etc).  Can I connect the Pico to my iPhone using the...

Can anyone recommend a relatively inexpensive amp for these?  Something less than $1,000 new or used

Where can I get an arm band for my AK120?

One of the things I love about iTunes and iPod is that you can create a random playlist from your whole library and then have up to 60 Gigs of random songs copied onto your iPod.   Last time I checked, the shuffle feature on my AK100 totally blows.  I always listen to music randomly, mostly at...

I have a question about shuffle play.  I always listen on shuffle play.  I have over 2000 songs on my AK100.  What really bothers me is that my unit behaves like this ... it will turn on the unit at the gym on a Monday and it will play 20 songs during the hour that I am there.  On Wednesday...

Well maybe they are toast.  :(   Does anybody make water-resistant IEM's that sound good?

About a week ago the right earpiece stopped working while I was in the middle of listening during a workout at the gym.  A few days later both ears were working fine.  Then yesterday the right earpiece stopped again.  This morning, I noticed that there is sound coming out of the right earpiece...

Thank you!  I will try this today.  I hope I can figure it out. 

I am pretty old too but I enjoy the variety of shuffle play when I am exercising at the gym with my AK100.  Anybody know the answer to my question about iTunes random song selections?

One feature I used to love with iPod and iTunes was you could create random playlists from music saved on PC and transfer to iPod.  So if I had 250GB of music on PC, I could create totally random selection of 32GB of songs and then iTunes would copy them onto the iPod.  Do you think there is any...

I have a question about shuffle mode.  I do not have any cards in mine yet, just internal storage.  Most of the time I listen in shuffle mode.  I think I have about 300 songs on my RWAK.  What seems odd to me is it seems like a limited number of songs (say 30 to 40) are shuffling over and over...

I am having an issue with my RWAK100, I have about 15 gigs of FLAC's loaded on it, no external cards installed.  I usually listen to it using shuffle mode for all songs.  What I have been noticing lately is that every once in a while it will be playing a song and, without finishing the current...

I am loving my new AK100, especially since I got Vinnies RWAK version.   I am copying music to the device and I need to ask a basic question about tagging.  I have many compilations such as Armin van Buuren albums that have 12 songs all by different artists.  So I don't want to see all these...

I have an old non-imod version of an iPod that is Windows based.  It has a couple dozen audio books on it.  The computer that it was synced to stopped working about a month ago.    A few days a ago I connected it to my new Windows computer which has iTunes on it.  The computer did not...

I just ordered a RWAK100 from Vinnie, can't wait!   Where can I buy a case for this in the U.S.?  Are there any options?

Where is the best place to buy an AK100 in the United States?

If I really wanted to buy one of these, do I have to order from Japan / China and wait weeks to get it? Does anybody sell them in the U.S?

I have been using iPod classics and iMods for many years.  I am wondering what kind of DAPs are out there now with relatively high storage capacity with good sound.  I think 32Gig would be about the smallest I would consider.  Suggestions?
