Myles, I have a pair of Linn Keltiks powered by four Aktive
Klouts. The Keltiks have two woofers, the system can be powered using three amps, low, mid & high. I upgraded from a
pair of Aktive AV-5140, so I just changed the Aktive cards
and ran the Keltiks until I got another Klout. In responce to your question, adding another LK100 with a similar bass/mid card will only give you a subtle improvement, not the kind you got when you changed your system to an aktive setup. If you are looking for a "big" improvement I suggest
that you either go with a pair of Ninkas which can be run Aktive with the two amps and cards that you already have or go with a pair of better amps, like used Klouts or LK-240.
