I have a couple of systems, but am trying to place the Jena ICs in just one of these. The Jena ICs link a DCS Delius to Jeff Rowland Model 201 monos, which are driving Verity Fidelios via either Luminous Synchestra Signature, or Poiema, or Stealth UR speaker cables. Power cables are Audience PowerChords (I am limited in the chords I can legally use in New Zealand). The Jena ICs have replaced a long line of ICs I have tried such as Luminous Synchestra Ref, Stealth PGS, Poiema, Kimber 1130, SPM..
As stated, the Jenas have some wonderful qualities in this system, but they are just a little too laid back. I can see some Jena Symphony SCs here on Audiogon for sale but am concerned they might similarly be laid back. Howie made me reconsider this assumption with his comment about using Jena ICs on their own.
