These are my reflections on the day.
CAVEAT
These are my views of hearing the DACs in my system with a range of rock/pop/jazz music. My system is nearfield listening with bookshelf speakers. I own a few DACs but for day-to-day listening I use a DDDAC which is a non-oversampling (NOS) DAC.

[Direct] means we went direct from DAC to power amplifier bypassing the pre amplifier.
We had two attempts at getting the Phasure NOS1a to work with a PC running the XXHighEnd software but failed. I was really looking forward to hearing this.
Before everyone else arrived, we had a quick listen to Colin's new top secret prototype NOSDAC with a different chipset to one in his ddDAC1794. Despite there being some teething problems with losing sound on one channel, it shows great promise. It'll be interesting to see if this is an improvement over his existing DAC.
In addition to the DAVE, Nick also used his Chord Blu transport and WAVE cables to connect them. Nick did a demo which clearly showed that his cables offer a much cleaner sound than the stock cables when connecting these devices.
MUSIC
Each DAC was played for an hour with a mixture of music. To allow for some comparison, we planned to play two tracks on each DAC but having an hour allowed us to use three instead.
Malia/Boris Blank - Celestial Echo from their eponymous album.
Fink - Biscuits from the live album "Wheels Turn Beneath My Feet".
Ezio - Thirty and Confused from the album "Black Boots on Latin Feet"
As it was the end of a long day, we only played the three test tracks with the Bryston and the Phison.
REVIEW
I'm not going to review each DAC but will identify specifics where I think it makes sense to.
The Chord DAVE sounded different to everything else I heard. The clarity and detail were incredible especially in the bass notes but it wasn't thrown at you; everything had some space. It was a very different presentation than I have been used to and in the end, I found it all too much in my system; I longed for something less impressive. In a complimentary system, I can't imagine anyone not being overjoyed with the sound this DAC produces. I'm certain that had this been a shootout, with quickfire listens of a track or two at a time, that the DAVE would have been voted the best of the day.
I could happily live with any of the DACs we used [except the Chord DAVE as explained above]. At no point were there any digital nasties like over-sybilance on vocals unless they were on the recording.
If you listened to specific parts of a tune, the more expensive DACs [Chord DAVE, Bricasti M1SE and Meitner MA1] were better in a lot of areas but I don't think that they were any better at tying it all together. Whether this is worth the extra sums of money involved is up to you.
Each of the DACs took a different approach to design but all produced musical sounds to a high level. That's not to say that they all sounded the same because there were variations that were discernable on the three test tracks.
Nothing I heard today has convinced me to replace my NOSDAC.
CONCLUSION
Not all DACs sound the same.
Spending more money may give better sound but may not produce better music.
Synergy is as important with DACs as any other bits of kit.
Reviewing this many DACs in a day is hard work.
An hour is plenty of time to get the flavour of sound of a DAC.
FINALLY
Thanks to everyone involved in making this a really fun/interesting day.
