Tried Burson v5i Opamp and feel good, then Funk has a special upgrade so give it a try.

The System

Listening with

Totem Acoustic Rainmaker · Speakers: passive 2-way standmount (1 in chambered aluminium dome, 5.5 in woofer)

Impedance: 4 Ω
Sensitivity: 87.5 dB (1 W / 1 m)
Frequency response: 42 Hz – 20 kHz (±3 dB)
Recommended amplifier power: 30 – 100 W
Other: crossover 2.3 kHz 2nd order; break-in 70-100 h; 356 x 173 x 231 mm

Matching notes: The Totem Acoustic Rainmaker is rated at 87.5 dB (1 W / 1 m) into 4 Ω nominal. Burson rates the Funk at 35 W into 8 Ω and 45 W into 4 Ω. At that rating the speaker would reach about 104 dB SPL at 1 m (calc., one speaker, before room gain). Totem Acoustic recommends 30 – 100 W amplifiers. ^{[1] [2] [3] [4] [5]}
