I bought the second switch on the advice of Rich at Network Acoustics - the guy who makes your ENO filter.

He said to me "the more switches the better" as long as their power supply is decent. He reckons the built-in supplies in the Ciscos are 'very decent'.
The more switches the higher the electricity bill. For something that's on 24/7 365.

I'm smelling bullshit when someone says the more switches the better. So if you had 100 switches it'd sound better than live?

In fairness, he wasn't trying to sell me them.

I don't think I've got 100 plug sockets, so 'better than live' is out for me, then ;)

The 2940 arrived this morning in little more than 24 hours. I was surprised by how small it is compared to the 2960G. Not a bad thing from the WAF angle as this one is in sight. :grin: I was anticipating having problems connecting my MR, but this was not the case and there was music from the off. I use the BubbleUp app. Initial impressions are that the improvement is not subtle and, if I remember correctly, greater than when I installed the 2960G around a year ago. The improvement mainly concerns the bass. There is more depth and clarity with a greater sense of authority. I am guessing but the benefits being mainly in this area could be down to having a decent PS near the streamer as well as close to the start of the ethernet chain. I can certainly vouch for the benefits of two switches and at £19 it is a steal.
I do not have a spare ethernet cable so borrowed the one which was connecting the NAS to the 2960G. I think a quality 1m one would reap benefits and, going on my experience with their USB and BNC cables, it is likely to be DH Labs. Their Silver Sonic seems to have similar specifications to AQ Vodka and costs significantly less. Will be a good use for the recent refund on my Who ticket. :grin:

I investigated the specs. They're not stackable.

An opportunity to have a forum pass round...

A. Google search has revealed that the 2960 series, unlike the 2940 series, is stackable. I presume this is why I can connect both.

Okay well after having Fedex e-mail me that my delivery failed at 11.58 and would be rescheduled when both myself and Linda my wife were in because of the restrictions I was on the phone to Fedex Customer Service at 1.56 when during the call a knock on the door and there is the delivery driver with package , asked while the customer service agent was on the line if he had called already and he said not this was his first call . Good way to get me agitated and wound up but at least i now have the new Blue Jean Ethernet cable .

Well connected the Cat 6 from the router to the Cisco Switch (on input 8) then replaced two inputs from my Music Server to the switch and from the switch to my main Netgear Power line plug with the Blue Jean Cat 5 . Best thing is it all worked just as it should a full system reboot and Music Server reboot and when everything settled down out came the music on my bedroom active three way system .

It sounds wonderful and I have to say it sounded wonderful before . Has it improved well I am not really able to tell as it just takes too long to do a switch and trying to remember what it was like before is difficult . However i can say with real certainty that it is not worse the music is still very easy to listen to and the quality is immense I am so proud of this system I want so many others to hear it as I would be amazed if they were not impressed . Hopefully if the Wam show goes ahead then I will take all of it and anyone here who is around can come and listen .

Back to the cable as has been said the build quality is good but not that different to the Cat 8 I replaced . You do get a proper test certificate of that exact cable so from a sense of OCD I feel confident that the correct wire for the job is now in place. I am not unhappy that i tried this but I would not be preaching from the rooftops that it is essential . If you only have short cables like mine so 3 x 1 metre then the cost is not huge and worth the trial .

What do you mean by not stackable?

What are you trying to achieve?

Why on Earth would you want to combine more than 1 switch into a single IP address - in a home or small business environment?

If you mean that you think that they are not connectable to each other, then that is simply not true. The whole idea of switches is that you can have thousands of them at a single site, all interconnected - in a network.
