I use a VH Audio flavor 4 cryo cord with my Symphonic amp. It is a very large, thick cord. Be sure to burn it in for a while. The sound is fantastic! The price: $160 and up depending on your connectors.

Someone else already provided info on the stock cord length, so I'll move on to PC recommendations. I second the use of the VH Audio cryoed Flavor 4. I use one for each of my Extreme Monos, and they seem to work quite well together, albeit I put in at least 400 hours burn in on the PC (but it wasn't a big issue because that seems to be the minimum burn-in time for the Extremes). FYI - I used to have a Stratos w/cap upgrade, and used a cryoed Flavor 2 with that amp. I previously tried a Groneberg Quattro cord with the Stratos and liked it, but movement of my equipment made the point moot as the Groneberg was then too short. For my ears, with my gear, I prefer the VH Audio PCs. FYI - Klaus recommends running Odyssey amps directly from the wall outlet, not from a power conditioner or bar.
Also, to muddle things a bit, I note I have not tried a Groneberg TS Premium PC with my gear. I bring this up because I have some TS Premium ICs in my system, and I feel they are a distinct improvement over the Groneberg Quattro PCs. Thus, a TS Premium PC may be a better candidate to A-B against the VH Audio cryoed Flavor 4 PC.
Oh yeah, I also dose my PC prongs (and other things like IEC prongs, RCAs and RCA plugs, speaker cables, etc) with
Walker SST. I strongly recommend using this product, albeit very carefully and according to the manufacturer's instructions, when testing out new gear; I feel it allows you to hear much more of what the gear will bring to your system.
YMMV.
