Mine sounds amazing feeding my amplifiers direct, DAC to amps.Stay with that, this way your hearing it at it's most transparent/dynamic best. As today's sources can drive amps just as good if not better than some preamps can.

Sticking in more unneeded electronics in the signal path is just adding more colourations. If you like those colouration more, then you should look elsewhere to change your sound instead of adding more unneeded electronics, eg: amp, speakers or even the source itself.
