What cables are you using with your NVA amps Richard?
I keep looking at NVA equipment on eBay but I'm constantly put off by potential problems of cabling and using a non-passive pre-amp. It says that any cable over 200 picofarads per metre is not advised but I haven't a clue where to find that kind of info about my cables.
My pre now (which is my DAC) has 5v variable output so is very far from a being a passive input in terms of voltage.
