Nope
But I've read enough reviews of ALL the portable amps considered to
be cream of the crop and if it's HUGE but detailed bass you're looking for then the Voyager is unbeatable. I forked out over £300 on the Lisa III XP and even though it had a bass contour control, the contour only works with bass frequencies so as you turn it up it seems to progressively flood the sound with bass and it becomes unbalanced. The Voyager boosts at low and high frequencies which lifts the sound - you get incredible amounts of very punchy bass but that balanced by the boost in the higher frequencies.
You also have the option to turn it off of course and then you get a very nice sounding amp with a flat response. Believe me though, once you try it with the contour on, you won't be going back to flat
Look, the best way is to buy one for yourself. Ignore that fact that I'm selling one

If you buy direct from GSP audio (the main Graham slee site) and you're not
happy, you'll get a full refund.
You have to be honest about what you're looking for.
If you want a detailed sound with great bass definition (but not huge bass)
and a DAC...get the Predator.
If your defining factor is a desire for massive bass that's not bloated, muffled
or sloppy then buy the Voyager.
Good luck!
