TOK, there is a continuum of this "lack" in the Nordost iterations from SPM onwards, and particularly with the IC's versus the spkr cables. Yes, it feels like "something" is being "filtered," as in removed, or ommitted. Valhalla is better with air infusion in source, but still pull towrds bias of source over void space. Also, earlier lines were more dominant upon upstream components in this existential, spatial and harmonic filtering; as line proceeds it has less tendancy to impose and pass through, but the "filtering" regarding dimension remains. I think its a great SS cable by and large, although not for more harmonically complete SS amps like the Ayre and Pass units.
I haven't heard the newest Jena's, so can't say for sure, of course, but the purist design and reports from others are very close to my impressions of the Walker-distributed Mapleshade Omega Micro Planar copper spkr wire (not IC's). I have heard some very good things about the Jena from some very good systems and ears, mostly running the Valykrie, now yours included with the Symphony. I think you would find some things to like in the Omega Micro too.
Good move from the Nordost to Jena.
