'Analog Dinosaur' succumbs to the joys of FBA : enter Raspberry Pi 2/IQ-Audio DAC+!!

[Halfway Tree]

It's possible to have 4 PCM5122 on the I2C bus, each could be made to be a unique sound card and then each could be EQ'd too. It would be a hack and need some specific Linux Kernel development but worth a play. I'll add it to my todo list :-)

That would be brilliant! Currently I'm only using 6 channels, with a simple passive between the two midrange drivers on my Linkwitz LX521s, but eventually would look at using 8 channels.

This is typically how this is being implemented at the moment:

and its ability to allow me to play hi-res music files, beyond the capability of the Sony. As such, I've welcomed it very warmly into my system, as being yet another highly capable music source .

Choice is good!

Marco.

Marco I know you are not a digital fanboy and I don't want to de-rail the discussion but so called 'high resolution' files are nothing of the sort. It's marketing-speak. They are no higher resolution that the redbook cds you own. If they sound better it is because they are different masters. That's all. I agree that alone is a good reason to have the facility to play them.

Hi Martin,

I tackled that matter earlier in the thread, near the beginning. If you don't remember, scroll back and have a look. Although I know where you're coming from, I disagree, and explained why.

Incidentally, the only thing I'm a "fanboy" of, when it comes to hi-fi, is whatever it is I consider produces the best sound!

Nothing else comes into it.

Marco.

Uhm...why does SACD sound better than redbook then? (ferrinstance...)
Could you explain in a bit more depth Macca what you mean?

(See what I did there?)

Marco -"...unquestionably sound significantly better than the much thinner Maplins Cat5e cable I had been using before"

The cable Gazjam recomended and you linked to is a Cat6 cable, which is built to a higher specification than Cat5e, also Cat5e is available in screened and unscreened, which may have had an effect, depending on what type your Maplins cable was.

can we keep this Ethernet cable discussion out of this thread ? It clearly belongs into the "network infrastructure" debate and not here. Otherwise we could still be discussing if a NAS makes the SQ better or if your router can contribute to cleaner bass.. please !!

Roops, I think it's relevant insofar as me mentioning it earlier as a 'new discovery', which is now done and dusted, and so I don't expect the subject to influence or dominate the main thrust of the discussion. Indeed, it won't be allowed to

Marco.

Only the 33 years for me, if I can include the degree that is...

We're not talking just IT here, the closer one moves in the chain to the actual DAC the further removed from IT one gets, and were into a murky world of physics.

My experience and suspicion is that DACs are fragile little things, and their performance can be degraded by electromagnetic 'interference', hence different connections and cabling can introduce audible differences, without affecting the bit perfect data transfer figures...but I'm only guessing as this area is out of the IT domain IMHO

good one !

ok, then I'm out. There is too much guessing going on ATM.

I took a look back but can't see anything. Anyway I'll start this on another thread so as not to de-rail this one as it isn't really relevant here.

[Marco]

ok, then I'm out...

Sorry, you've lost me....

I've done precisely what you asked, not the opposite, so chill out!

Marco.
