Based on what I see with their specs on wattage output, the difference is probably negligible. Takes twice the wattage for +3db more volume; approx +10db for a perceived doubling in volume. So takes significantly more power than you probably realize to make a difference. Plus, my understanding of why the Q701s are a bit difficult to drive has to do with voltage swing needs as much as insensitivity. And which would be better at that I don't think you can tell by the specs that are given.

At this price I could easily buy a used Asgard, which has much more power and would likely drive the Q701 very easily. I would like to stay closer to $100, and I've heard the Vali goes very well with the Q701. It has a higher output impedance (6.5 ohms), but the Q701's impedance is 62 ohms, so it is more than 8 times the output impedance. The Vali also has slightly more power than the O2, so if the O2 has no problem driving the Q701, the Vali shouldn't have a problem. At the moment, I think I've decided upon the Q701 with either a Vali or Asgard 1. If I can find an Asgard 1 under/around $125 I'll go for the Asgard, but if not I'll likely go for the Vali.


I very recently picked up a new O2 for under $100, including the power cord.

 

I think you will be better served by either the O2 or a good used Asgard 1 over the newish entry level Schiit hybrid.  While I have not yet heard the Vali, a number of people have reported a high noise floor in some of the units.

I have not heard the Vali but read the sound is ringing from tube microphonics.. The later Asgards are dead quiet.biggrin.gif

Where was it that you found the O2 for under $100? And I did want my setup to be as quiet as possible, so I will look for an Asgard or O2 within my price range. I may be able to afford an Asgard if I buy a used Q701, but I'd prefer to buy it new. All I really need is an amp that can drive the Q701 well (which all of these amps do) and be neutral/slightly warm but also be very quiet, and be under ~$110 or so. The O2's neutrality might be better because if I need more bass I can mess with the settings on the X3.

Years ago a member Markl wrote a review for the AKG k701 series that tells a great story about the k701 burn in process. We get to hear opinion about the sound at 50hrs to over 500hrs of descriptive burn in SQ changes.......lol
