Just Bought used JVC DX1000 for 600$ from headfi guy, plugged into my Yulong D100 mkii Dac and headphone amp,
it has got wider soundstage then 650 but the highs are too much too me, may be the DAC is revealing the highs. Can
you guys recommend any warm tube or solid state amp.
Are you saying the treble is too hot or overly extended? If I had to make a criticism of the DX1000 it would be that I find them a tad rolled off although never hot. It seems that your hardware is the issue here.
