I downloaded the amazon app, It’s listing a lot of music I’ve bought from amazon but I’ve never used itunes so nothing there and it can’t see the music on the Core, probably just as well.

I could try it on the bike (Indian Roadmaster)’s speakers but I find even the radio too distracting when I’m riding though I did manage to use Waze through them last weekend from the iphone.

Hi Yeti,

if you've just downloaded the app, your Amazon files are still in their 'cloud' and if you want them offline you have to download them on the actual device first. But I suppose you already know this. Amazon Music (of which I, with some discomfort because it was not my intention, seem to be an endorser) is just a music player so it hasn't any UPnP part I believe, it's not a streamer. Again, I mentioned it because it has a nice layout, nice graphics, works well, sounds good.

As for the rest of the thread, I suppose it has spontaneously generated a sort of sub-sub thread which would deserve to be called Kindergarten, and which I'll do my best to ignore because this little idea was not intended for folklore but, at the same time, who am I to prevent people from having fun?

Enjoy, best

Ardbeg10y,

time ago I already voted your pic, in the system pics thread, system of the year or so. I find the Lego Minis as gear decouplers a fantastic, imaginative and clever idea, very smart on the technical plain. Your pic here should be the official image of the Children's Corner. Thanks for the contribution.

An aside if I may, apropo the above: if the radio is too distracting on a bike, then surely it is also so in a car. Unfortunately the problem is that too many car drivers drive on ‘autopilot’, not concentrating enough on the road, which is how the majority of accidents are caused between cars and bikes (motorised and not), and the reason why bikers and cyclists have learnt that to survive they must not only concentrate but try to predict the actions of people in their metal boxes, often playing music, not infrequently playing it loudly.

I could never get on with the sound of these lossy files, but as I rip my CDs and stream them at home, I have a ready source of lossless music to transfer to my portable player. A much better sensory experience, but then, I also like my tea strong, with milk, not lemon. 

Chris,

I know that there are the Pono and the Astell & Kerns, but I just wanted to give an innocent suggestion to those (like me) who – while trying to listen to music seriously on the home Naim system [and trying to overcome the number of upgrade/updates/itches/tweaks that lurk behind us when we sit on the couch]  – also like to play a few low-res 'songs' on a portable device like an iPhone on a train or a Metro wagon, often using the device's own earbuds. Yet, even in these impaired environmental condition, I can't avoid feeling saddened by the visual poorness and the aural mediocrity of the Music app. That's why I simply suggested a more 'gratifying' way to enjoy lossy music on the move. 

Lately, I have a crush for Mahler's Second, and even on a crowded train, that mp3 gives me some thrill and prepares me for a day of fatigue. I have no doubt that a FLAC or AIFF file would be better (although I listen to the 1962, Bruno Walter recording)(*) on a 'serious' player, but there I am, with my iPhone and a graphically, functionally adequate app.

I note that Lego characters’ arms appear to be rather randomly set, is that actually the case, or is it a result of painstaking experimentation with all permutations on all the characters? If not, then maybe that is worth trying, because as you know attention to such fine detail can make all the difference.

Also, is the asymetry of the stacks of books significant? And do you think and subject for the books would do, or is Kameleon important?

IB, there you go ... not many grown up people understand that Minifigs are Creatures in the real sense of the word. They are created, and are alive! Its not that they are randomly set, they move all the time. Luckily enough, they are smart and understand that a few need to keep bearing the CD Player, otherwise this lovely collective won't survive. We are never too young to learn!

I can't capture the eyes of my kids when I tell them stories about these rebellious Minifigs.

Regarding the ordering of the books: we try to convey a secret message. We wait until the message gets picked up by either aliens or some mystical orde and then we will re-arange the books to enlighten them with another message.

To do my duty and write something which is considered by many as being serious and on-topic:

I bought HiFi Cast last year, I use that to control my NAS / Streamer.

Fast, and no serious bugs detected. Before that, I was using Linn Kazoo.

Surely the ideal way to dust the system is to turn the volume up far enough for it just to bounce off.  No effort involved.  You won’t hear anyone complaining either.

Sorry Massimo, I think I am to blame for the dust thing. It is the child in me…….

No worry, as I wrote we already have a perfectly acceptable sub-section called Kindergarten.. And I loved the Springfield joke.

Are you using the Android or the PC version?

How does it manage playlists, does it download them to the Naim Streamer?

Android. I have it on my old phone.

I'm not using a Naim Streamer but a Raspberry Pi + Dragonfly Black as streamer and a Raspberry Pi + DigiOne streamer + Chord Mojo Dac. Works nicely for both. I have not studied the precise logics of managing playlists - I have my albums on a Nas, and I noticed that once I've lost connection (e.g. collecting kids from school) and return back, the streamers are still following the album and when the album is ended, it repeats from where it started.

+ maybe important to mention: I mostly listen to mid to late romantic symphonies these days, where 1 piece of a symphony number can take up to half an hour each. So managing playlists is not really important to me.

In past generations of kit, I had a floorstander that had a front firing port that I could hear contributing to the sound. Not having a supplied bung or a hollow tube to tune from the maker - I used these kitchen sponge clothes cut to size and fitted within the port tube. Really helped in damping resonance without changing in any way the way the loudspeaker was loaded.   Although needed replacing often once they started to dry out and shrivel.

My Tivoli One radio fires bass downward through a port at least 1' diameter on the bottom, separated by just a few mm. from the shelf, thanks to 4 rubber half-spherical feet. It definitely need damping, so I'll consider this.

GFFJ found that a stack of books on top of the T1 did wonders, particularly when it included a really thick one from Churchill.

Glad this thread has got back on track as I thought the OP’s original idea for it to be a ‘tip sharing’ thread was a really good one. Small one from me for anyone with a Naim CD player that uses a puck with the little rubber hoops (most of them I think?) . If you ever experience that issue of the disc slipping and spinning uncontrollably you’ll know that it’s caused by those rubber hoops becoming too compressed over time and their shape becoming too flat. They need time out of the player to get their correct shape back. Probably more obvious to some owners than it was for me at first, I finally stumbled on the brainwave solution of buying a second puck and substituting puck #2 in as soon as I heard the first sign of a spinning disc, leaving puck #1 on a shelf, face up to recover it’s shape. When puck #2 eventually suffers the same issue, put the now revived puck #1 back in. I’m sure most owners will already be doing this, but perhaps worth a flag just in case. Spare pucks can be bought from your dealer or online from TomTom for e.g.  Kevin

Massimo, a really good way to control the bass on the Model One is to use a roll of lint dressing. Cut a piece off the roll so it’s about 3cm long and then roll it so that it is a good fit. You can make it tighter for greater bass control. 

The effect of partially blocking a reflex port like this is more complex than one might think.

As you are slowing the movement of the air moving into (and out of) a Helmholtz resonator, you are affecting the effective mass of the air in the reflex port and therefore affecting the tuning of the port's phase relationships (and hence it's frequency characteristics) as well as the amplitude.  This affects the interaction of the port output with the forward output of the cone.

To have a more selective effect on amplitude (with less effect on phase and frequency), you should use a thin perforated disk rather than a long diffuse plug, or use a much longer but narrower tube.

The Tivoli One is hardly a pukka reflex cabinet,  the little port just adds a bit of oomph & I suspect control facia stuff is a bit leaky so not much helmholtz'ing is gong on.    The problem with mine is its on a stone worktop & its back onto a tiled wall & my problem is a double boundary effect ( I suspect I'm not the only one )  I jerry rigged a shelf to get it 30cm off the worktop & although that fixed it the final vote went to a significant other & she said its rather than spoil 'her' kitchen,  its was OK in its original position on the worktop.    I've experimented with port damping,  various densities of BAF wadding plugs & also a complete block with a cork plug,  nothing really fixes the small bass hump,  it is what it is with it,  but its not good with it completely blocked.

Well, it was what Naim’s Jason Gould suggested when he was in my house once, so it’s good enough for me, and it works really well, regardless of what theory might say. Sometimes, one can be over technical. Stuffing the hole with bandage - what could be simpler? If it has the desired effect that’s all that matters. 

The rubber rings shouldn't touch anything if there's no disk present.

I have a couple of CDs that are thinner than they should be and even freshly rotated (with a pin inserted through the loop to grip against) rubbers won't touch them.

Yeah, I had a couple of those too. I found most would eventually play OK after repeated attempts (especially if I switched pucks )  but refuse consistently other times. Not too much you can do with those discs AFAIK. As you say, such discs are usually too thin around the centre hole.

Thanks, I wanted to be sure what lint was, and also because there are many types, to understand clearly which one from the pic. I am now using a rolled piece of a stuff called something 35, it's what they use for front grilles in some loudspeakers and has 35 air bubbles per cubic inch (or cm.). Does the type you use have a thick or a loose texture? Ciao M.

A few posts back I was convinced this thread was already packing to be ready for Richard relocating it to the Padded Cell, but I see it's sudddnly taken a HiFi turn again, so maybe I was premature in my thinking!
