Well I guess you'll have to use it as a mantel piece for the time being:lol:.

just use any old phono cable in the meantime..

some would say it makes no difference anyway (but WE know better) :)

Length of low loss CT100 Sat cable (Air cell dialectric) terminated with phono plugs will do you for now, a bit stiff to use though

Thanks LEo, in fact I have a number of home-brew I/cs of that description. Will post impressions in a day or 2

Is this modification appropriate for WM8716 + 4562NA modded 7520s?

I was just about to put the MCL 5/6 caps back before I read this thread.

Yep. I am even using it on a TC-7520 with LM4562NA.

Hi Stan,

Is there likely to be any benefit from swapping one of the SPDIF phono inputs on the Caiman for a BNC socket? The digital cable connected to this would be a BNC to BNC design.

Thanks.

None that I can think of. The TC-7520/7520SE take the incoming signal and recreates a perfect square wave version of it instead. That square wave is sent to the DAC chip. So even if the incoming digital signal is ragged or the cabble impedance is way out, the actual data sent to the DAC chip is a tidied up version of the dodgy one.

I added a 75R BNC socket to replace one of the phono inputs, mainly because my co-ax leads are terminated with BNC's anyway

Thanks Stan, that's very interesting and clever stuff. In that case I'll probably not bother. I'll give it some thought. :)

Thanks Leo. Did you notice any difference in quality at all? I guess it will be difficult to tell if you used an entirely different cable before and after.
