PS Audio PWT / PWD digital connection

i own the pwt and pwd.

i have used hdmi, but it is not my interface of choice.

yes, you can connect the hdmi cable to the i2s digital input of the pwd. try it, you may like it.

i own ps audio's top of the line hdmi cable but i don't use it.

Can an ordinary HDMI cable be used between the PWT and PWD I2S ports or is a specialized cable needed?

No special HDMI needed, any will do. You do need HDMI to use the I2S feature, unless you use the soon to be released Bridge. I2S is the way to go IMO.

Thanks for the help Mrtennis and Srwooten!
