In a power conditioner, w/Mun S/G/O 3.3uf, .22 CuTf VCap is about perfect.
Expect long break in. Those JFX r impressive, but never 'loosened up', they remain rather clinical, cold in comparison. The VCaps will go up & down for a long time, but they resolve more detail & flesh out the lower mids in a way nothing else does, including Dueland. S/G/O & CuTf is the best I've heard, remaining musical w/gobs of resolution. The 'center of gravity' lower, has a certain 'grip' on the music. As always, everything in combination....
