Ignore Crna39.
He is a 'tool' for Pass Labs amps (just check out every single one of his "Answers").
Strange thing is, in 4 years, not a single mention of comparing the Halcro DM58 amps till now?
And how and why did that comparison occur when he is such a proponent for Pass? if you believe that, you believe in the tooth fairy.
If you are spending this kind of money, you need to hear both amps, driving your speakers in your room.
One will do it better than the other but no-one can tell you which one?
I've had the Halcro DM58 monoblocks for 3 years and they are the most neutral, transparent and distortion-free amps I've heard up until the Soulution 700 which sound remarkably similar to the Halcros.
