Which headphone amp is technically superior? Help

I don't have the electronics accumen to figure out which of these two amps has better specifications. My headphones are Sennheiser HD600s.

The reason is that there are two amps at the same price with two different specs and I am trying to figure out which amp is objectively superior. I understand there are other factors such as component quality at work that determine which sounds better, but right now I need someone to explain the difference in the technical specs. Thanks!

AMP ONE

Power output 150mW/600ohms
Headphone connection>32 ohms
Output impedance 20ohms
Signal to noise 94dB ref. full output
Frequency response 20Hz - 20kHz/0,2dB (10Hz - 120kHz/-1dB)
THD 0,005%
Headphone jack 3-pole ¼" (6,3mm Ø ) phono socket
Power supply type Mains-fed outboard power supply
Output voltage 16V/500mA AC
Power consumption 16V/120mA AC
Dimension W x H x D 130 x 79 x 133mm
Weight 1.000g without power supply

AMP TWO

Power output 700mW/30ohms, 110mW/300ohms
Headphone connection > 30 ohms
Signal to noise 110dB (115dB - A weighted) at full output
Frequency response 20Hz – 20kHz/-0,03dB
THD (IMD) 0,003%/30ohms, 0,007%/300ohms
Gain 12dB
Headphone jacks 3-pole ¼" (6,3mm Ø) phono socket
Power supply type Mains-fed outboard power supply
Output voltage 16V/1.000mA AC
Power consumption 16V/230mA AC
Dimension W x H x D 103 x 72 x 151mm
Weight 1.080g without power supply

Dcstep, I don't understand why you are saying that amp 2 is more powerfull than amp 1. Amp 1 has more power than Amp 2 as indicated by 150mw into 600 ohms, while amp 2 has but 110w into 300 ohms. I suspect that amp 1 is capable of more than the 700mw into 30 ohms of amp 2.

At any rate, both set of specs show that there shouldn't be any problem driving any set of headphones and therefore go by listening.

Personally, I would go by cost!
