Yeah that makes some sense, in relation to an idea I had. (It might just be straight right, but only when played balanced louder than SE goes.)
I'll try explain, but am whacked tonight so might mess up... Like I have to try get it straight in my head before I can explain it. Also I might be totally wrong so take it with a pinch of salt, but this is what I read. I read about this in articles about amplifiers and power output.
When we see the ohmage of speakers, it's only a nominal value apparently to set a numerical standard. I have read that the impedance of speakers changes as the frequency of the sound changes. Anyway, as frequency of sound drops, the impedance of the speaker drops. This means that the current moves faster, meaning the amplifier has to make more power output. It has to provide more current (at given voltage) to provide same volume. Meaning as the sound goes lower, the amplifier (or TT2) has to put through more power.
That's why I said what I did a few times in the last pages, which is this. Maybe folk who think the TT2 lacks bass power are listening to it on louder volume levels than I am. (When driving speakers directly of course.) That they are reaching the point where the TT2 can't match the power required to maintain low frequency volume. (Whereas I don't even need to push the TT2 on single ended, because I listen quietly.) …. I think this is why sometimes we read things in reviews related to this. Like when they say some amplifiers cannot control speakers at low frequencies. Either the amplifiers can't provide enough power at low volumes, or can't provide it fast enough.
The theory is the same for SE vs balanced. On balanced there is more available power to them. In SE they may have pushed the TT2 into a region where it struggled for bass volume reproduction. Whereas in balanced out, they never really reached that threshold, because overall they had more volume at their disposal.
I mean I really honestly do need to go over 0 (zero) on the TT2 volume numbers. That probably leaves me well within the region where bass still gets enough power. ……….Moving on, even having said this, I feel more comfortable using the TT2 as a DAC only, with an amplifier. Like if I ever do need more volume, I would prefer to be running an amplifier. Partly for the reasons above. Partly because some amplifiers can sound harsh when pushed very hard. We read about amplifiers hardening up, or the separation going wrong, when amplifiers are pushed hard. It's also said that you should not push amplifiers too hard anyway. That's because even if they are not quite at full volume, they start to distort. That type of distortion destroys speakers.
