High End NDAC on the radar?
Posted by: T38.45 on 12 October 2009
Hi,
is there any news about the high-end NAIM DAC?
Price, schedule, functions?
Thanks
Ralf

That is absolute nonsense! Try
www.upnp.org.

As I say ... the analogy only goes so far ...
My point is that when you are talking to a printer via ethernet, the information that is sent is a postscript type information which the printer has to convert into the actual image that is put on the paper ...
In the same way a UPnP renderer receives from the UPnP server WAV information (or AIFF, or FLAC, or MP3, or whatever IT supports) which is has to convert into information that is recognised by the DAC - either internally or via SPDIF to an external DAC.
The data transmitted over the ethernet cable in both cases is not directly convertible to printer "dots" or input to a DAC for conversion to analogue audio.

PS and I didn't start the stupid comparison to a printer...

I thought your analogy was fine, and whatever other points of view might get expressed here the DAC's just a DAC...

Whether UPnP is used or not, it still uses ethernet protocols over an ethernet connection first. I haven't looked into how UPnP does it's thing but you can't take the transfer format out of the loop and regardless of how the info is transferred it will still need to be formatted into something a DAC can understand. A player/renderer with a way to control it locally would always be required. It's not a player. It's a DAC!!!!

Quite right js ...
The NaimDAC is a DAC
The Linn Sneaky DS (and it's friends) are players

After some deep thought, I've remembered some sound advice.

Can you provide some links to reviews. Would be nice.

Maybe on some other planet but not on this one
How do ethernet printers work on your planet then?
Ethernet is a layer 2 protocol. It is a broadcast media and does not know where its target is (so it could not pull any info). It sends the MAC address (machine address - which is the ID of the NIC card in the computer running the target application)out on all ports it is connected to. Any computers, other than the target machine, ignore the packets since it is not their address. The target machine strips off the ethernet layer and reads the network (level 3) protocol (IP is the most common) starting the proceedure to find the particular software application in question. There are several other layers (the conceptual model has 7)that address such things as error correction,
syntax etc required to find and interface to the target software application. The software application would be where any Pull came from and the level 2 protocol would not have to be ethernet to acheive the same result.
That is how it works on my planet (Earth)

Why do people keep on about ethernet as a forms of traversing music, is this in operation on any device?
Ethernet is a means to deliver data in packets, at either end needs to be a computer to make sense of it, and if necessary turn it into musical magic. Ethernet in its own form cannot do this. Surely?
The obsession with making all manner of interfaces be a music one is just befuddling to me. USB is not a music interface, Ethernet is not a music interface.
Naim have created a dac which has the industry standards for music interface built right in. If your computer is unable to output industry standard audio interfaces then why the hell are you looking at a 2K dac, your computer is shit, upgrade it first, then come meet the rest of us in the 21st century.

Sorry for misleading. I meant, as JS says above, forum members, dealers, Naim/ASL figures etc... You know, the people that matter.
I cant say Ive read a "pro" review in the last few years.

Hi Gary
Ethernet came into the picture with streaming (particularly multi-room). Ethernet and (typically) the TCP/IP protocol enables a local area network (LAN). Esentially LAN technology allows a device to appear as if it is directly connected to a remote machine/application (or indeed to several at once in a multi room set-up). As an example a Linn DS requires a remote NAS (network attached server) which because of fans and disk drive noise is best situated outside the listening room, conversly the Naim HDX has the hard drives inside so it does not require ethernet etc to play. But the Naim can also interface to this technology to stream to another room or to download album art from the Internet.Ethernet/IP just move data around they have no ability to decode or play music, that requires specialized hardware and software which can be on one machine or spread out over a network.

Bob I am more than fully aware of what ethernet is thankyou. However the ethernet cable carries data in the form of packets, music bits in the form of light for instance does not travel that way, therefore an ethernet lead cannot directly be used as a 'cable' to carry music.
You seem to agree with me
OI do not understand therefore why people say 'what about ethernet to carry music' it cannot do this in the form they are on about.
