TMP Audio ANT is the amplifier. This is a hand-made (tube pre-stage, + transistor) from a Hungarian manufacturer. Its performance is not very high, i.e. rather small 9 Watts. I'm currently using the little Dittons with a Musical Fidelity X-A1 amp. I wouldn't say it's better, maybe because of the higher performance it sounds more adult.
