Re: [SlimDevices: Audiophiles] Did I dream this? Digital Cable length

 Hey all. I thought I remember reading that there is a minimum desired
 length for digital Coax cables between components.  I currently have my
 SB Recevier running into a CI Audio Dac using a Bolder Cable digital
 coax that is only .5 of a meter.  Do I gain anything besides flexibility
 if I get a longer coax cable between the SB and the DAC?  I know maximum
 length is an issue, but I swear I read that Coax's also had a minimum
 for optimal performance.
 
 
 Thanks in advance for any insight.
It depends on your dac. If the DIR1701 chip does its job correctly, if
the receivers are perfect and cable exactly 75ohms, then the length
should not be important. 
In all other cases, there will be differences, but not necessarily
audible for your setup.

If I was you (living in the States) I would have added a very nice
Sherwood Newcastle in my list. ;)

 hmmm thought that would be the case
 
 1 side of the room is 3 double glazed sliding glass doors, the rear of

 so not really much that can be done
 
 might perhaps look at just upgrading the Rotel then if I'm still not
 happy with the sound :)
 
 thanks for the advice!


Actually, that's not all that bad and quite common.   

First, your open kitchen is fine.  Nothing you can do about that and
I'm sure it has enough odd angles in it to keep the waves from focusing
on one particular area in your A/V room.  

Second: The rear wall.  As long as your speakers are out from the wall
you are fine.  And you can always add acoustic foam _under_ the
paintings.  Refer to the Cardas website for optimum placement away from
the rear wall.

Third:  The glass wall may be the easiest one yet to affect a real
positive improvement.  There are a few companies that make 'acoustic' or
noise-blocking curtains.  Typically for city environments where your
want to eliminate street noise from entering.  I bought some when living
in Boston and when we moved to the ocean I found that they make for
great interior absorption also.  I like looking out when listening to
music, but the sound is much more refined when I close the curtains.

No. Mainly because of the carefully-made analog stage. ;)

 Craig

Yes, the AIR Studios are associated with George Martin.

As for the OP, this is smoke and mirrors and just a means to increase
the unit price and make AIR Studios some licensing bucks. Not the same
as paying for a Disney or NFL branded AVR, but almost.

IMO, spend your money on buying a high current AVR (read stay away from
most big name Japanese units).

Re: [SlimDevices: Audiophiles] Did I dream this? Digital Cable length

2009-11-04 Thread ar-t

The DIR1701 does not do its job correctly, which is why they don't make
it any longer. 

The receivers are not perfect; all contribute a significant amount of
reflections.

Cables are not exactly 75 ohms. Really, really good ones are spec'ed at
+/- 0.75 ohms. Average ones are spec'ed at +/- 3.0 ohms.

So, the length is important.

16' is not necessarily the minimum optimal length. You can get by
with less, but certainly not 0.5 m.

Unless you think that a.) jitter is nonsense, and/or b.) you don't
care.

Some DACs handle jitter better than others. So, what may make a world
of difference on one may be barely discernible on others.
