@mattw73 It might not have the most punchy slam but the bass is accurate. It’s tight, detailed, & nuanced. It’s kind of weird, it doesn’t sound like it’s super deep or expressive but I can hear/feel it in the walls behind the couch..different from my prior dac. The 15th also puts the vocalists in it’s natural position where my other dac put it a little out front of the speakers no matter the track.
Using my Ultravalve or SET amp I do get more "meat on the bones" & some extended spatial cues. Maybe a hint more than my sabre dac. I certainly don’t feel like it’s pulling out any more information or more resolving than a sabre dac. But I can detect the slight smoothness or lack of hardness on the top end in comparison. That is probably the biggest difference. But then I feel you are losing some of the clean edges of the notes in space & perception. There is more depth to the soundstage but without those etched lines separating everything. There is separation..but not as pinpoint focused.
Thank you for pointing out those details; in particular, the depth of soundstage I’m craving from an upgraded DAC—separation, cleanly outlined edges, pinpoint focus, and articulated bass, etc. Which Sabre DAC were you comparing it to?
I don’t think you’re being overly critical. I believe $2-3K is the price point where diminishing returns set in for a DAC. I compared the Gustard R26, a highly praised R2R DAC, with a lower-priced Sabre DAC from SMSL in a fairly extensive audition after a 150-hour break-in period for the R26. On my humble system, I couldn’t meaningfully detect a sonic difference between them. However, I did notice differences among the seven DACs I’ve tested so far, which ranged in price from $200 to $500.
For now, I’ll probably put the idea of purchasing the 15th on hold. I’m afraid the sonic performance you described might be the ceiling for all R2R DACs in the $1,500–$2,000 range.
