I have found more differences between lower priced dac's than higher priced dac's.
In terms of the higher priced dac's you pay more for that last 5-10%, but generally they all sound very good above $2,000.
With sub $1000 dac's I've found a wide margin of difference. Some cannot resolve enough detail, some cannot produce a wide or deep soundstage. Some can.
Choose wisely.
