Got a set of Canton Ergo 120 speakers , currently using a Plinius 2100i Integrated amp to drive em
Cantons specs:
Bass drivers  2x 260 mm Midrange 160 mm Mid/tweeter 38 mm tweeter: 25 mm
Power cont/peak 200/350 Watt
Sensitivity 89,4 dB
FR 18 - 30.000 Hz
Impedance 4 Ohm

Plinius 2100i specs
100 Watts continuous power per channel into 8 ohms, both channels driven from 20Hz to
20kHz at less than 0.1% Total Harmonic Distortion from 0.25 Watts to rated output.
160 Watts continuous power per channel 20Hz to 20kHz into 4 ohms.
Dynamic headroom1dB or greater at 8 ohms with music.
Frequency response 20Hz to 20kHz ? 0.2dB
DistortionTypically 0.05% and IM at rated power, 0.1% THD and IM worst case prior to clipping.
Saturation120 Watts per channel or greater into 8 ohms.
Voltage swing87 Volts peak to peak per channel
Current output30 Amps short duration continuous per channel.
Rise time Typically 4 microseconds.
Slewing 50 Volts/uS
Hum & Noise 90dB

Considering a Bryston 4b-st as a power amp
Power Output 250 watts per channel into 8 ohms 
400 watts per channel into 4 ohms
800 watts, bridged into 8 ohms 
Gain 29dB (unbalanced)
23dB (balanced)
Distortion < 0.007% from 20Hz to 20kHz at 120 watts, IM or THD
Noise >106dB below rated output
Slew Rate >60 volts per microsecond
Greater than 120 volts per microsecond, bridged
Power  Bandwidth <1 Hz to over 100 kHz
Damping  Factor Over 500 at 20 Hz, ref. 8 ohms
Input Sensitivity
Balanced  2 Volts in = 100 watts at 8 ohms
3.0 Volts in = 250 watts into 8 ohms
5.6 Volts in = 800W into 8 ohms Bridged
Input Sensitivity
Unbalanced  1 Volt in = 100 Watts at 8 ohms
1.5 Volts in = 250 watts into 8 ohms
2.8 Volts in = 800W into 8 Ohms Bridged

Not sure if there will be any improvement over the Plinius , Waddya think? I have a big room , like listening quite loud , love tight deep bass..
