    FS: SHANLING M5 DAP

    @john321722, we can discuss this via PM and will PM you soon. But John's reply does remind me something I forgot to mention: the DAP doesn't have internal memory and TF card is not included in this sale. I can put in a 32G Sandisk or Samsung TF card for additional $10.

  3. Item: Grado RS1i headphones Location: Melbourne Price: 600 Item Condition: very good Reason for selling: Not using Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: One of those legend headphones with its own character, no need to say too much, you either like/love it or not... Got this from Addicted to Audio a few years ago. Only listened for a very short period of time as still prefer to speakers. It has been sitting in the boxes for quite a while and it's time to have a new owner will use it. Happy to demo and can post at buyers cost. Pictures:
  4. If it's really a power issue (the R-N602 not providing consistent sufficient power to the hard drive), you can use an externally powered (ideally BC1.2 complaint) usb hut instead of replacing the hard drive. Such as : https://www.aliexpress.com/item/ORICO-U2BCH4-USB-Charging-HUB-ABS-With-12V2-5A-Power-Adapter4-Port-USB2-0-BC1-2/32835051478.html

    Yamaha NS-1000 best speaker stands poll

    This Ikea step stool could be more solid, each one can support 150kg and you can stack them to suit the height. https://m.ikea.com/au/en/catalog/products/art/40265164/
  6. I remember there was a long post here before discussing this, but I can't find it now. I remember that the key is you only send to the name and the address the guys registered in paypal, take photos of the shipment and keep all shippment documentation. But personally I would avoid accepting Paypal.

    SOLD: FS: Magnepan MMG speakers

    Only got the Yammies for a few days, still need to find the best position. As you can see in the picture, I only put them on the floor with wooden spikes, still need to source a good pair of stands. But to my ear, the Yammies is better, especially the magic midrange and clarity.

  11. Item: Magnepan MMG speakers Location: Blackburn North VIC 3130 Price: $800 + shipping cost Item Condition: Excellent Reason for selling: Itch Payment Method: Pickup - Cash, Paypal Extra Info: The Maggie is about 3 years old and I am the 2nd owner. Bought these from another SNAer 2 years ago and here is previous ad link(more nice pictures there): http://www.stereo.net.au/forums/topic/87987-sold-fs-magneplanar-mmg-speakers-can-freight-safely/ For those lazy to open the link (I am also lazy to write), I copy some details from there: -------------------------- They are flawless, in as new condition. I had some custom made Jarrah side trims made to replace the plain looking painted black ones. I just didn't like the original black ones and I reckon the Jarrah sides really smarten up the speakers. BTW the side trims weren't cheap. The internet is full of reviews of these speakers and from everything I've read they're ALL positive. They really are a lovely sounding pair of speakers. They present an ENORMOUS soundstage and give an amazingly accurate reproduction of music. They really are one of those speakers that when given space they really do disappear. They certainly aren't a bass heavy speaker but the bass they do have is nice and tight. -------------------------- I have been using them in a smoke & pet free room so far, so they are basically in the same condition with 2 years ago, but just have been burned in and have customer stands to raise them up about 15cm from the ground which get them an even better soundstage IMO. The original stands are still there and it's quite easy to swap between stands. Also worth to mention, the previous owner built a very robust box for shipping them to me and of course I have been keeping the box, so now I am very confident the maggie can be shipped to interstate buyer very safely. Feel free to contact me if you have any questions. Pictures:

    Would like to take them, PM sent.
  13. Raspberry Pi + PicorePlayer (or a number of other software choices) can be a cost-effective solution if you have a spare DAC that supports USB input, but just need a bit hands-on. Some links for your information: http://archimago.blogspot.com.au/2017/03/howto-building-and-installing-raspberry.html (You don't really need to touch screen in there, just use your phone.) https://sites.google.com/site/picoreplayer/home/how-to-1

    Should I upsample with Chord DAC?

    Upsampling and oversampling seem two different things. Refer to this article: http://www.audioholics.com/audio-technologies/upsampling-vs-oversampling-for-digital-audio To start with, we must review the system as a whole and look at the terminology. Two main parts of the whole system we are going to consider are upsampling and oversampling. In the purely mathematical context, they are similar operations. When practically implemented though, oversampling refers to using a higher sampling rate than needed to run the A/D or D/A converter thus increasing the rate of the signal. Upsampling is on the other hand a rate conversion from one rate to another arbitrary rate. Oversampling in the ADC has been around for quite a bit of time, while upsampling of audio that results in a simple rate conversion is relatively newer.
