DAC Measurements vs Actual Experience

I have spent the last two days evaluating which of these two DACs I will be keeping:
1) Benchmark DAC3
2) PS Audio DirectStream

I'm foregoing the use of a dedicated preamp; the chosen DAC will serve that purpose.* 

I had read up on the technical side of each of these exhaustively before purchase. For those of you who aren't familiar, the Benchmark DAC3 measures quite well in every category. The PS Audio DirectStream, on the other hand, not so much. In fact, Audio Science Review places these two near opposite ends of its SINAD (signal-to-noise-and-distortion) list with the PS Audio being positioned near the bottom. Stereophile also provided measurements in their review that painted the PS Audio in an unfavorable light. 

And yet the DirectStream is proving to provide a sound that is more, dare I say, musical. It's a bit more relaxed, sounding a tad reserved in comparison to the DAC3, and the presentation of 100 Hz and lower seems to be slightly vague, but it's also less edgy, possessing a better soundstage, and is overall ever-so-slightly more enjoyable. So what am I doing wrong?

* Is it worth considering putting a dedicated preamp downstream of the DAC3 in hopes of gaining a more favorable sound?

I have heard a few recent Linn’s, including the Selekt DSM. A little veiled compared to my preferences but not bad. I was tapping my toes with them, but I do that for all good music.

Just to show a little more enthusiasm for my HPA4 + DAC3B combo I want to say that I have been listening to the headphone section of this preamp and it sounds great. The real fun part for me is hearing so much new musical passages in well know material, it is shocking. For example, I was playing Stairway to Heaven the other night and I heard John Bonhoim (sp?) play some drum track that I had never heard before. I am hearing stuff like this on many well known recordings. This maybe not what everyone wants in their music, but for me it makes me feel like I am in the studio with the performers.

I actually had a similar reaction with the Benchmark DAC3 HGC + AHB2 amp. It was not as good as what I hear now with the HPA4 preamp but that THX circuit on the Benchmark really works for me.

I need a new amp to make my speakers sound as good as the headphones, likely the CODA #16 and/or the AHB2.

I suppose we all prefer different sound. I owned Benchmark at the same time as older Linn Klimax. I got rid of Benchmark because it sounded like POS next to Linn. 
You do you and carry on with measurement first mentality. I use my ears and keep the equipment that sounds good to me.

Hey Chesebert can you tell me who wrote this in 2011 and whose fairly limited posts have been almost all about DACs and a large portion about Linn DACs?  Biased?


I personally don't mind listening to mp3 (320kps) using Klimax DS. It sounds a whole lota more analog and musical than the same CD played back on the CDP that Klimax replaced. Yes, mp3s sound great, CDs sound amazing and hi-res sounds heavenly.

Contrary to what this implies these two concepts are not mutually exclusive.

@rbstehno I don’t understand what you are trying to imply here. I write about stuff I own and heard. I do have a lot of experience with Linn DS as I have owned various DS over a decade. I don’t talk much about my Ayre and Chord front end because they don’t sound as good as top of the line Linn DS. 
Re the Klimax in 2011, it was a true revelation back then. Playing 320k mp3 from Linn Radio was a treat.
