I have a 30 metre run of Cat 6 linking my NAS to my server and have just ordered the TP Link convertors and a 30m fibre optic cable to replace this set up. Hopefully all should arrive within a week or so and I'll let you know if the changes are audible to me.

There is some thinking which says that there should be an improvement, but that it is caused by rejection of electrical noise generated from the NAS setup rather then the Cat cable acting as an aerial.



I didn't type what was quoted - your quote should be attributed to ServerBaboon.

The LAN conversion to fibre and back smells a lot like audiophile thinking.
There's no consideration for the conversion switching, and there's no consideration for the switching noise of the SMPS at each converter.
Then there's the network latency the devices will add ...

I'd be surprised to hear that it makes a difference, but I'm not closing the door on the possibility.

There is the cost and reliability to consider.
You've gone from a single connection hop using a medium that is maintenance free if it's left alone (I've never had to repair a cable or outlet that was kept away from human intervention), to one where you've added four potential breakdown points (2 x SMPS and 2 x converters).

Reliability is always underrated and never considered until something's broken.
There's a lot to be said for reliability.

Sorry Chris...cut and paste not used properly!

Fair points raised, but I have ordered the kit to try out...if there's no noticable improvement it will be returned so nothing to lose really, other than the time spent doing it.

Yeah probably my fault for overly complicating quoting Embarrassed.

The reason I mentioned this was that I saw it as an extension  of what you were observing with the CAT 6 change, and doesn't your observation about the buffering negate your concerns about network latency.

@suggs If you follow IT good practice and make sure you have an adequate  DR strategy in place (leave the Cat 5 in place for easy swap back Smile) then you an quickly deal with failures. Please report back on what you find/hear.

I have wondered about potential for noise from the SMPS, but if it works then there is the chance to change them. I have a managed switch with four gbic ports so hopefully I only need one TP link device.

Various bits of GSP Kit ..well two so far, unless you count the cables that is.

All three drives are internal and connect into the motherboard and same PSU. The music was on a 3.5 inch hard disk before.

Hello,

Without knowing anything about the condition of the original disk (speed / file system etc.), could the level of file fragmentation on the old drive be a factor? Assuming that you copied (as opposed to cloned) the files onto the new drive, any fragmented files would be re-assembled contiguously (although any downstream buffering would almost certainly overcome this).

I'd be interested to hear how you got on replacing the Cat.6 with a fibre link.

Kind Regards

James

Hi James, I came to a similar conclusion that the old hard disk was the issue and it was pretty full supporting your shrewd suggestion on fragmentation. I think someone else made a similar suggestion too. The curious thing is that the Squeezebox Touch buffers the datastream but I can still hear that the disk drive and more recently the cable swap (again buffering should 'fix' this) with/without the different network topology (assume this is more cable length, going through hubs, other data on there) each sound different!
 
Given the cost of switching to fibre I'm probably going for an audiophile Ethernet cable like MeiCord.

The hard disk the music had been on started to play up a couple of weeks ago. I did the obvious maintenance work and concluded it was simply worn out. It was the hard disk from a PC I got 5-6 years ago and became the storage and scratch disk when I bought an SSD-based PC last year. It has now been replaced by a new 2TB hard disk and I will repeat the HD vs SSD experiment over Christmas.
 
 
My new MeiCord Ethernet cable is a revelation. You can read the reviewers and user comments so I will stick to saying it is a big improvement in overall clarity, separation of instruments/voices and sounds more natural than the other cables I tried. It connects my PC and Squeezebox directly from a second Ethernet card I added to my PC a few months back. I have tried several specs of standard cable and this cable is a lot better for music. It is good VFM in my opinion and I'd encourage anyone thinking about buying a MeiCord to go ahead.
