Thank you Flummoxed and welcome to Head-fi.
I won't have much to add to what has already been posted about Dave. I am was enjoying Mojo and Hugo a lot, and wanted to know if Dave is much better, and once I heard Dave, as the HiFi + reviewer said, it only takes a few moments to understand how special Dave is, as good as Hugo is, once I heard the (even bigger than Hugo) soundstage of Dave, and how much more musical it was, I knew I had to buy one. So I won't be changing my old and heavily used car for a few more years as a result of this, but music is much more important to me than a car.
Chord have received a huge amount of orders for Dave and it is in great demand all over the world, and mine will arrive in a few weeks (I was told 6-8 weeks when I ordered it)
About Naim - I use a squeezebox touch with my Hugo through optical out, and that is the same source I will use with Dave. Or maybe a Laptop running off battery. If you are familiar with Naim, I am using a RCA to Din cable for my Hugo.
I've been an audiophile since a young age, when I was impressed by the Bang and Olufsen systems I heard back in the early 80's, and loved the era of Vinyl and analog tape. I then heard a Naim system 10 years ago and loved it, but Dave is for me almost the final destination of my audiophile journey. (the last one will be the Chord million tap DAC, but I think we're quite a few years away from that). And keenly waiting for hear recordings made on Davina.
I never liked early digital, and for me Dave is a musical dream come true in terms of being able to hear the microdynamics, rhythmic qualities, emotion, 3d soundstage, spacious sound, musicality from the good old red book CD.
Can't wait to get it !
