Hi,
I’m considering a pair of Technics SB-G90M2, they have good specifications on paper; however, my only concern would be their 86 dB sensitivity.
My current amplifier is Cayin A100t, which according to its specs, outputs 70 watts into 8ohms. the Technics are 4 Ohms; so, I assume my Amp could deliver 100-140 Watts into 4 Ohms. Unfortunately, I couldn’t find more accurate information about my amplifier, and it only shows the output power at 8 Ohms equipped with KT-88 output tubes (mine came with EL-34s), therefore, it’s unclear what the real output powerat 4 ohms is.
Wondering if this tube amplifier would be a good match for these more demanding 86 dB speakers? I’m aware of impendence fluctuations and I know the Amp can drive them just fine, but I am not sure if 100 watt per channel -assuming that’s what my Amp can deliver into 4 Ohms- would be enough for these speakers to make them sound as intended, meaning, good sound quality.
(I don’t nor am planning to listen at high volume but have a larger room with high ceilings).
Below are the specs.
Many thanks,
