Given that you are into tube, maybe you should stay away from 86dB sensitivity speakers. Again, how loud do you listen to music? You might have to make some compromise depending on which is more important to you: the amp or the speaker. The common wisdom is: tube amp for high sensitivity speakers and class D amp for low sensitivity speakers. In my case, my speakers are Raidho td1.2 with 87dB sensitivity and my amp is AGD Audion mkiii with 100 watts per side. Sometimes I feel I could use more power but for the most part, it’s ok.
Amplifier recommendations for 86 dB Sensitivity Speakers
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,
