I heartily recommend the PS Audio Digital Link III. I cannot compare it to the others as I have not heard them. For the money, $995 or less, it is a bargain. It is slightly warm in presentation, is still dynamic and articulate, has 3 inputs-Toslink optical/RCA coax/USB. I love mine and have no desire to upgrade.
Need dynamic DAC
I'm looking for a dynamic DAC with great imaging. The DAC could be tube or solid state, don't matter as long as it fits the bill. Thanks.
