Great to hear that you like the opticalRendu package. When I get the Chord Hugo TT2 for the bedroom I will pair it with my existing microRendu streamer. I will get the same opticalRendu package as you for my existing Benchmark DAC3B in the office rig. Looking forward to lying on my bed and listening to tunes at this level of quality.
Yesterday, I bought a new headphone cable for the Empy. It is the Wywire Platinum. It is copper with some graphene. I got a lot of positive reinforcement to buy it from Empy owners on a Head-fi forum, especially now that they have a 40% off sale. So cost with tax and delivery was $400. It is supposed to have more detail than the stock Empy cable and other positive attributes.
I will say again how amazing the Empy is. It is getting even better after 200 hours. It is the most non-fatiguing headphone I have ever heard. Just cannot praise it enough. This with the stock cable.
I have also been doing a comparison of some new Benchmark StarQuad XLR’s. Benchmark calls them professional grade cables (vs consumer grade). At first I was not that impressed compared to the much more expensive Audience Au24e XLR’s I was using. However, after about 100 hours these cables maybe good. I need to do some flipping back and forth with the Audience, but I do like these StarQuads now. Not sure which is better yet. Though the StarQuad cost $200 for 1 foot and 15 feet pairs. The Audience was over a $1000+ for 1 foot and 9 feet.
