I love Benchmark products. I have LA4 | AHB2 | DAC3B and owned many older DACs from then. Last night I did an apples-to-apples comparison with my DAC3B and my new Musetec 005. I was just listening to Nina Simone. I used ROON Group streaming with the gain on the CODA 07x preamp matched for both DACs. I used 2 almost identical Sonore OpticalRendu's to do the Group stream. Both DACs are ESS based chips.
I will cut to the chase and say that the Musetec at $3300 is much better than the $1700 DAC3B. The Musetec does everything better than the DAC3B. More bass, thicker or denser sound, and better top end but with a bit of softness to it. For example, on Nina Simone's SINNERMAN the percussion on the start of the track was so much better on the 005.
I have had a few DACs come into my system; I always kept the DAC3B around because it was like comfort food for me. However, I am now thinking of moving my DAC3B to another room along with 1 of my Sonore OpticalRendu streamers because so far, ALL music seems to be better on the 005 vs the DAC3B. In the past I preferred hard rock on the DAC3B, mainly how electric guitars sounded on it. The 005 is now the king for all music.
The DAC2 and DAC3 sound the same to me. the DAC3 HGC and DAC2 HGC were not great at low level volume when used as a preamp. Adding the incredible LA4 or HPA4 solves that issue. I have never tried the Musetec 005 direct to amp. I have only used it with a CODA 07x preamp and Benchmark LA4 preamp.
The Mustec maybe still available for the $2969 sale price and also 30-day home trial. Benchmark also has a 30-day home trial so there is a way to test them out before buying.
