I owned the FORESTS in a prior system, so I know their unique/ particular sonic signature, their strengths, AND their weaknesses/ warts very well.

They crave

- a lot of “grunt” ( ergo hi-current AMPS …. WPC are meaningless,,,)

- beefy solid state instead of tubes

Top integrated amp suggestions to mate up to the TOTEMS include , inter alia, top offerings from SIM AUDIO, AYRE, PLINIUS. ..... These are all top high-current gear frequently used with TOTEM speakers at the audio expos.
You will NOT need a subwoofer with these floorstanders powered by a robust S/S integrated  .,,,full stop. 

I would concentrate on and audition first these three, I favour a top SIM AUDIO kit. (I’ve auditioned them all ) SIM AUDIOand TOTEM are both based in Montreal and they are paired to voice each other’s products.

TOTEM even had its own beefy SS integrated "AMBER" amp with a ton of grunt but now discontinued, that was a JV with SIMAUDIO based on a SIM integrated amplifier platform design.

How are your subs connected?  Speaker level?  You may want to reevaluate sub placement and setup. I suspect that your amp is not the culprit. 

Get the Stereophile Test CD and use the bass tones to evaluate the placement of the REL subs in your room. They may not be in an optimal position.

Your listening spot may not be optimal either!
