I'm not sure what your saying about DAC. Is your ranking Mojo, Halo, MSB? I had a discreate with 1 PS and the USB module. The Mojo was better.I can definitely relate to the frustration of not being able to unhear amazing sound. Which MSB did you compare the Mojo to? I have owned the Mojo Mystique Evo with upgrades and now own a MSB Reference, in my system there is quite a large gap. I replaced the Mojo Mystique Evo with a Holo Audio May KTE (2 box R2R) and the Holo was better in almost every way (for my taste in my system). Of course the MSB is another significant jump up.
I think it's all down to personal taste and music preference. For me, although I like the analog sound, I also value speed, visceral impact, tangibility and transparency. But for someone else, those things could be much further down the priority list.
For DACs at mortal prices, there is the Pilium Elektra that's getting a lot of rave feedback, as well as Aries Cerat Helene and Kassandra. Though I think none of those will be 100% neutral.
Lastly, I can't help but reflect back to Capital Audio Fest, where the best sounding room to me had the cheapest digital source. It was the Kharma Exquisite Midi, powered by CJ Art 300 monos and Gat 2 pre, all fed by a 10+ yr old $300 CD player, Cambridge Audio 740c. It had the most natural yet polished sound, literally like performers in the room. This is the same show with $1M+ VAC, Esoteric and VS system as well as the Bending Wave room with Wadax Ref DAC and server feeding Gobel speakers. Seems like there is more than one path to get to audio nirvana.
Where is you signature with equipment? I looked to see what your vinyl. is My reference for digital performance is vinyl, or tape. When I get my digital better than my vinyl, well then it flips and I go improving my vinyl until it surpasses my digital again. Its a horrible game I play with myself. Neither beat my tape.
To your point of CD players, I have been on a little kick looking at SD players. I am not getting much traction though. The point is a SD player done correct can be like a CD. A CD done correct is superior to a server via USB to a DAC because the CD player bypasses the kernel. All the jitter that is in the Kernel/USB path is eliminated. Done right in a CD player, your talking the data stream and sending it I2S directly into the DAC chip. Or so my very limited understanding of computer audio has been lead to believe. Sure there is still a lot to do with PS, Isolation, vibration control etc. But simple usually rules.
Pilium is $40K. Mojo EVO is $9K to $11.5K. A big gap in price. But yes, $40K is approaching a more reasonable cost for people with a "mature" system.
