I have been using the DX100 more and more recently driving Cans and IEMs. I am getting some surprisingly good results and some not so good but still a very pleasant listening experience.
Right off the bat, for me, the LCD-2 and HE500 is not too great out of the DX100. It sounds pleasant enough but you can sense the sheer lack of power, grip and control compared to using other amps! Surprisingly, the best amp to my ears for the LCD-2 is the Triad L3 sourced by the Baldelius usb DAC. The HE500 best driven by the Violectric V200 and sourced by the same DAC, signal from the JRiver media player via ASIO.
Back to the DX100, the Headphone that I have really been enjoying driven by the DX100 is the Shure SRH 1840. It really is a fantastic combination and betters, using the HD650. Bear in mind I am listening with the EQ. switched on and flat. The 1840 just seems to hit the sweet spot with the DX100, dynamically, soundstaging and tonality wise.
With IEMs, I do favour the W4 with a silver/gold cable on the DX100. Again everything just sounds so correct. Great extension on both freq. extremes with a really full and lush mid. Spacial cues are well portrayed. Tonality, again is just about right and one can listen for hours. I received my 20 BA driver IEMs yesterday and will be listening extensively in the coming weeks initial impressions have been very favourable.
Will have an interesting weekend, when I add the Violectric V800 DAC. I will be using the DX100 as transport to the V800 and will make comparisons:-
JRiver > ASIO > Bladelius usb DAC > Triad L3/LLP > LCD-2 Vs DX100 > coax > V800 > V200 > HE500. The two rigs are very similar in price so from that perspective it will be interesting to see how the two compare.
Overall, I have to say I am very pleased with the DX100 and the many ways it can be utilized. As a DAP, source and transport. A extremely good buy!
