HDMI i2s Cable


I'm looking for an HDMI i2s cable to go from a Matrix Audio X-SPDIF 2 to a PS Audio DirectStream DAC. I realize there are a lot of options at various price points.  I'm trying to stay around $500.  Anyone have any experience with the Tubulus HDMI i2s cable?

I have the phasure hdmi2 and recently acquired the tubulus argentus. Long story short, Phasure has a bit of emphasis on the highs and a more forward presentation. Tubulus has more low end weight and nice mids and midbass, with quite a neutral upper registry. Both cables are good. Need to consider how the rest of your system sounds like. 
@docroasty.  The Tubulus sounds like it will work best with my speakers my Tannoy speakers.  How flexible is the cable?  I only need about .5 meter, if that's an option.
I found it quite flexible. Not as stiff as some people say. Can take short bends quite well. The connector is good quality but is quite big and need to take into account that portion can't bend. So I suppose just plan the route well and order an appropriate length. Also consider the orientation of the i2s ports eg if one is horizontal and the other vertically aligned, may need to allow a short length to twist the cable a bit. 
I'm going from an Audio Matrix X-SPDIF 2 to a PS Audio DSD.  I will certainly look into the orientation before I buy.  Thanks.
Hey guys, can a cable be made to adapt the older style i2s plug like audio alchemy used to the hdmi format? Thx.
