Analyzing DACs


As I am new to the hifi hobby, reading various product reviews and noting the details of the test environment have made me very confused.  I understand Stereophile is the hifi bible. In the publication’s DAC published tests the reviewers almost always tested the DAC connected directly to the amplifier. I think I understand why—nothing in the chain influencing the DAC sound. Is that the correct assumption? If that’s the case why incorporate a preamp if the DAC has a preamp section that is a common feature even on high end DACs? I’m in the market for a new DAC. I’m trying to avoid unnecessary components if possible. Any thoughts would be appreciated. Thanks.

I am familiar with the Soul Note product story and philosophical/implementation approach. Near the antithesis of Benchmark designs. Curious to see how someone who is pleased with Benchmark will respond to Soul Note. There’s only one way to find out.

@decooney 

after playing the dac for a while it was one of the most sterile and boring sounding dac units I’ve ever tried or owned. The dac got returned for a full refund, thankfully. Agree, you cannot pick a component by measurements alone if you care about how it sounds too.

+1, Live and learn. There’s no better teacher than experience.

I would say that the one advantage to following the ASR sheep is that the units recommended by ASR can be resold very quickly and without taking as much of a haircut in the process. 
 

That is a good observation.

@mastering92 And not all DAC chips are created equal. The easier it is to implement/ it can withstand all kinds of substandard parts tolerances and teperature variations/ the worse it will sound. Rather than have all parts when, which measured, do not vary wildly and will compliment eachother to create a high-performace unit

The tried and true formula seems to be cheap and low quality level parts then utilization of off the shelf OP-amps. One thing is for sure, these OP-amps will consistently provide very good test measurements.That’s the apparent objective target, measure good.

The sound quality reproducing music can be subpar. But that seems besides the point, and not the important criteria. The game plan is great measurements at a very low retail cost. OP-amps and their generous NFB will get the desired result.
