Setup help

Hello all

I have just bought some new kit, and would be most grateful for any tips concerning its setup. I'm not after general things like not touuching snaics and things, but specific to the models.

They are a CDS1 and a NAC52/52PS. They are both being serviced before I get them, which should be at the end of the week. The CDS1 will be on a mana stand. I think it is called a mini table, it has only one layer of glass. The rest will be on a bolt together sound org stand.

Specifically, I would like to know:

Is it worth upgrading the burndys to black on older 52s?
Is it right that older 52s can still power prefixes?
What order should the 52, 52PS, CDPS, NAP160 and a manky sony tuner be on on the rack?
How long is a burndy cable?

Thanks very much for your help

Ben
