Tonearm cabling for Graham Phantom

I used Graham IC-70 Right Angle DIN to RCA and also PAD Venustas DIN to XLR. Different results. Both sound good.

does it have to be right angled ? does straight din to rca work ?
whats the difference between the two cables ?

Right angle or nor depends on the Space you have below the Armboard. With the Raven Armboard you can use both. I use a right angle one for example.
There are lots of choices out there. Depends on the Design (shielded, real Phono Cable or rebranded RCA), the interaction with the rest of your chain, copper...silver....
I made last year a comparison with
PAD Venustas
XLO Signature Phono
Siltech Phono
Graham IC-70
Kondo KSL-VZ
Cardas (their latest at that time)
and a few others I forgot.
The PAD can create a huge soundstage, but I did prefer the airy Speed from the XLO, the Graham IC-70 was another cable which showed a very good balance in all frequencies from top to bottom.
The other ones were much more expensive but didn't show that kind of balance, most were dominant in one or the other area.
When you use the Search here you will find lots of posts about Phono cables.

thanks for the inputs syntax
