S/PDIF

Logitech Squeezebox Touch with EDO and hiFace1 based USB DACs/converters

I spotted this blog over the weekend http://www.aysabtu.dk/blog/.

It explains, in detail, how to connect to a Squeezebox Touch to install a suitable Linux driver to enable a M2Tech hiFace or EDO to work connected to the SBT’s USB socket.

The performance when connected this way  using my hiFace 1 is significantly better than I was getting using the S/PDIF output from my SBT.

There were two elements that confused me: one was forgetting that case is sometimes important in http links and the other in logging in as root.

Here is the original instruction in italics and below it my suggestion of what to do

▪         Open a root SSH session (default password: 1234)  and execute the following 5 commands all followed by “return” (newline). The last one will reboot your SBT. Please be aware of any non-intended line-breaks inserted by your browser formatting the text.

▪          ssh -l root “IP Address of Player” <Return>

▪         root password (default is 1234) <Return>

Next I’d like to try the hiFace 2 as a comparison.  It should be even easier as it doesn’t require a special driver under Linux (or Mac).

Let me know how you get on.

Pure Music – an interesting start

I downloaded the demo package of Pure Music (the playback only version of Pure Vinyl) today. A quick listen using my TC Konnect 8 as a firewire to S/PDIF interface to my Naim DAC with 555 PS Power Supply was enough to make me take up the $79 limited time offer.
I need to have time to seriously listen to this combination and to also try the hiFace M2Tech I have had since before Christmas.
To summarise the listening results, the performance with Pure Music was significantly better than with iTunes alone. Cleaner and more interesting. Memory playback was even better. The sound didn’t have the shiny, chromium plated character so common in computer audio. It had solidity and grip.
My only concern in the short-term at least is in the rhythm. It might not have the true ‘drag me in’ character I find essential for long-term enjoyment.
Much more as soon as I have time.

In the meantime…

This is the first major revision for this product in over 7 years. This takes the CDX2 into new markets delivering greater performance and far increased flexibility. The price remains the same.

The new version CDX2 adds a switchable S/PDIF output on a 75 Ohm BNC connector for the correct impedance match.

More Musical Fidelity V-DAC versus the Cambridge Audio DacMagic

Over the past day I’ve had a chance to listen to the comparison in two systems, both this time, using the coax S/PDIF input.  Overall I prefer the Cambridge DacMagic.  The DM is a little more even handed: on first listen it sounds a little flatter than the V-DAC but after a while it’s obvious that vocals are a little more intelligible even though they are further back in the mix.  The MF has a litte more LF energy, a slightly more forward vocal area and is a little better at the 3D stereo stuff : it recreates reverb tails with far more authority.  What it doesn’t do it hang music together in such a strongly cohesive way as the DM.

OK, these differences are not huge and you may think that the extra hundred (ish) quid for the DM is just too much for the small differences.  Have a listen for yourself then you can judge.

For those interested in upgrading the power supplies of the MF V-DAC I compared the supplied walwart supply with the Maplin and although there were differences with the Maplin having a touch more weight and grip, the differences were smaller than a change of digital cable might bring.
