You've got good comparison selections to make. IMHO it is ENTIRELY up to YOUR ears to make the determinations. The posts you receive can point you in directions to audition. That said, I would suggest, if possible, you take a listen to the JMR Reynaud Trentes. Soundstaging, vocal reproduction and some of the other qualities you seek can be found here. Will they lift your ears particularly -- Dunno. The suggestion is that if you can, give them a listen.
