there are numerous price points within both Nordost and Transparent; if you are asking about the very top level of each product.....i am familiar with both. i own 2 sets of Nordost Valhalla interconnect (i use to own 6 sets) and 2 sets of Transparent Opus speaker cables. i have tried both Valhalla speaker cable and Opus interconnect in my system.
i have had at least 20 other brands of cables in my system for comparison since 2000 and prefer my cables to any i have heard. i do prefer Opus interconnects to my Valhalla but i have not yet found the budget to upgrade (although i plan to).
to directly answer your question; at the top of the line i consider Transparent Opus (or it's one step down Reference MM) the very best cables i have heard......but they are truely 'silly expensive'). the Nordost Valhalla is certainly one of the better cables out there. the Valhalla can be too open and energetic for some systems.....so some consider it 'hot' or 'edgy'. that tells you more about the system it is used in than the Valhalla. i would think in your system which is a bit on the 'mellow' side the Nordost Valhalla would be quite synergistic. the Opus would be on another level beyond that.
to be fair; i have only done a few comparisons in the last couple of years so their are many cables i have not tried.
as always; YMMV.
