Now I was wondering: does it make sense to insert a RCV Passive Pre Placette Audio between the pre and the power amplifiers, in order to take advantage of its remote, without losing any of the sound quality I have at the moment?Try just the Passive Pre Placette between your source and the Krell (without the LS5 in).
You may be shocked at the transparency, dynamics and less colored sound you get.
