Short reply in brief:
FORESTs demand a lot of “grunt” to permit them to perform at their max.that means high- current and lotsa amps delivery. WPC specs by themselves mean nothing.
(1) pair them with high-current, high-end , solid-state amp only
(2) Do not pair them with tube amps
I owned TOTOTEM FORESTs before in a prior system . I simultaneously owned their ARROs, so I know their strengths and warts very well.
With the FORESTs, I had to upgrade the amp to a S/S bi-amped rig ( not bi-wire) with a high-end integrated amp paired with a matched spec stablemate power amp, just to get them to perform at their true max potential.
my BFF amigo audio friend borrowed them to test-drive them in his top strata high-end CARY tube amp system . In brief: just plain yuk! Comparatively, they were flat and lifeless until he pushed the volume knob to a 2 o’clock position on the volume knob . At which point they were quickly irritating, and predicating a dial-back to a listenable level. But alas, back to no dynamics, flat, et al and a poor match for a low(er) level listening
Choose wisely.
