Keyword there is 'seem' -- there were always a plethora of DACses, but fewer FOTMses (flavors of the month). Now there just seems to be more. Yes, pretty much.
Seriously -- the questions are: how good is your hearing, and where is the point of diminished returns for you? I have found that most material sounds pretty much the same out of a several hundred dollar DAC and a several thousand dollar DAC, so my point is somewhere less than a thousand. I might pay more for additional functionality (Cambridge Audio 840c seems like a bargain, considering what it does), but unless I win the lottery, I just can't bring myself to 'dew et'.
The only way to do this -- the only way, those that claim they can tell good from bad in a short listen are lying -- is to somehow arrange for an audition in your own system for a weeks-long period of time. This is usually done by actually purchasing the item. I have found that my best bet is to purchase used, and sell used, that way there's minimal financial outlay to me. (I consider shipping and any loss of value the price I pay for the in-home audition.)
Sure, one can look at the specs and the reviews -- how else are you going to determine which ones to audition -- but ultimately you have to hear it for yourself to decide for yourself.
