I find a bedside net radio easier to use (and more acceptable to my
better half) than a bedside computer. (She did complain that the Pure
Avanti Flow I use is rather large - and I must agree with her on that
point.)


Out of interest, which net radio(s) did you try?


At present I am having a play with a Roberts - big black box but I've
forgotten the model number at present!

The main advantage of a net radio for me is the availability of foreign
stations (like BR Klassik and France Musique) at reasonable quality.


Are they not available as net streams you can pick up with your computer? I
know the AVRO stations and various other European Classical ones are as I
do listen to them occasionally.

Slainte,

Jim

Yes, I believe they are. However, it is likely that the satellite feed
will be of a better quality. (BR Klassik, for example, is 320kbps
MP2.) I take the digital output from the satellite receiver (its
onboard circuitry is audibly poor) through an external DAC, an
amplifier and Quad electrostatics ('57s).

Overall it is not at all bad - and I get to improve my German and
French listening skills to boot! (Swiss radio is best for this because
the announcers alternate between French and German.)

Right. However I was asking about your comment re using net radio. I was
assuming from the context you were saying that BRK and France Musique were
an advantage for using a net radio device as the rx over using a computer,
etc.

I've found all kinds of music on net stations with the announcements not in
English. Fortunately for me, the streams often have an accompanying set of
tags that label the content for when I don't recognise it! :-)

Slainte,

Jim

For me, the main advantages of a net radio are that it is silent (no
fans or hard disks), it starts up faster and it is in a different room
from my computer.

The main downside of the one I use is no digital output to feed
external equipment.

This has been a concern for me. However it is possible to get computers
which make little or no noises. Albeit with a cost and some searching
around, etc. The Shuttle 'PC' I use has its fan disconnected, uses a
fanless brick PSU, and I have a SSD instead of a conventional HD. So it
makes no 'noises off' when I am using it to play audio, iPlayer, etc. Using
Ubuntu helps as it is quite happy with a 60GB SSD and only occupies a GB or
two.

I now also have a new laptop with a fanless PSU brick and a 60GB SSD. This
does have a fan, but it almost never comes on when I am simply listening to
the radio iPlayer or LPCM soundfiles. Does come on when using the 'TV#
iPlayer, though.

The main downside of the one I use is no digital output to feed external
equipment.


With the Shuttle I've ended up feeding digital via USB to a DACMagic, and I
then run an optical spdif from that to my Meridian 563 to break any ground
loops and get reclocking. Bit OTT but sounds good. :-)

With the Laptop I feed out its optical spdif to Pioneer CD recorder that I
also use as a player in the room where I tend to sit and use computers.
Meaning to try out a cheaper USB device, but as yet lack the round tuits...

Has anyone reading this tried, say, the 'Firestone' USB dac that has an
optical output?

A few words. :-) Many years ago I used to travel a lot when I worked in
mm-wave astronomy. Made kit for 90 - 400 GHz receiver systems and took it
to telescopes, etc. So did pick up 'FrangleDeutch' which was a guddle of
various European languages. But I've only ever been able to do that on the
basis of 'hear and learn'. Enough for some purposes, but hardly general
fluency! Found *English* hard enough to pick up! :-)

FWIW Many decades ago I was working in Tolouse for months. Project to use
Concorde 001 to fly along the track of a total eclipse to get prolonged
shadow for mm-wave measurements of the solar atmosphere. This mean I did
pick up some of the local dialect French. Mainly words for tools like
screwdrivers, equipment like transformers, etc, and how to order food and
drink.

With me was an academic who'd learned 'good' French at school. The problem
for him was that came across as a 'posh accent' to the locals. So they used
to pretend they could not understand what he said and turned to me to
explain as I spoke with the accent I'd picked up from them. :-)

But I can't now recall more than a few words.

Later on, most of the visits to telescopes were to Hawai'i. Less of a
language problem, but found people kept assuming I was Australian. ;-

Fun whilst it lasted. I love the views from c14,000ft up a mountain. And
despite being very unfit I never had problems with the lack of atomsphere.

Was one of the reasons I later got my old research group into making
mm-wave radars etc for volcanology. So they could boldly go up volcanoes
and have fun with big boots on around the world. :-)

Slainte,

Jim

No, I have not found the need, so far, for any external DAC to go with my
Mac mini, the analogue output sounds most satisfactory to me. A snaglet with
the Mac is the the analogue and optical outputs both emanate from the same
3.5mm plug'ole so both cannot be connected simultaneously, unless someone
knows otherwise.

Would an external DAC get around a PC's inherent resampling.

Googling found this from a well known supplier :-

Same is true with my new laptop, but that doesn't bother me as I
just use an external DAC as I assume that will be better than the
analogue parts of the laptop!

I've been able to get output from the standard soundcards that is without
resampling. But in each case only with the 'default' sample rate. I've now
tried three totally different 'PC' machines (with Ubuntu/Xubuntu) and
every case the default insists on playing all digital output with the same
sample rate, regardless of the rate of the source material.

Using the DACMagic solved that problem, but at the cost of having to use an
external add-on USB DAC of course! Plus I think that then limits me to 16
bits per sample, although I can't say that currently bothers me much!

Ahem Yes, I had known about that as was thinking of contacting Russ about
one. :-) But I was wondering if I was going to be 'first into the field'
again wrt using one with Linux.

Slainte,

Jim

There is a little USB DAC from Maplin which looks to me to be very similar
to the "Firestone" except that it only costs a fraction of the price. I've
used the Maplin DAC for some time and have been very pleased with it.

David.

Is it this one?
http://www.maplin.co.uk/Module.aspx?ModuleNo=34128

I've been looking at that as a cheap way of getting toslink output from
my laptop to a Minidisc, have you tried it in that mode?

Ah! Thanks. I was wondering if they did one. I just got a 'preview'
catalogue from them and had looked though it for that sort of thing with no
success.

Can you recall the part number? If not I'll just see if I can find it.

And does it automatically follow the source sampling rate?

And how does it indentify itself to the 'PC'? The DACMagic reports itself
as a specific 'USB Headphone Set' as that comes from the USB chip they use.

....and do you know if it works with Linux? :-)

Slainte,

Jim
