Tickfight/Tvad, Grant was right, I was joking, hence the wink ;-). I've 'chatted' quite a bit with Grant over the years, and I know he is no shill. I just attempted a bit of humour seeing the same reco twice tonight from Grant, but it was just in fun. No ill will intended.
I've recommended certain items more than once myself. :-)
As for the question, between these two players, for dynamics, large orchestra, etc, I'd say the Droplet would give Tickfight more of what he's looking for. The RA Opus 21 is a very nice, smooth liquid sounding player, but can sound rather polite and refined. Not exactly dynamic, the Opus 21 is more recommended for vocals and small jazz quartets, IMHO.
Since I see Tickfight already has the Droplet in his system, I'm inclined to ask what he thinks he's missing.
Tickfight, what about the Droplet leaves you yearning for more? Not dynamic enough?
You have to be careful what you wish for, because there are always trade-offs. You may find a more dynamic unit, only to discover later that it's more grainy in the high's.
I'll agree with Howard (Boa2) here, you won't find anything that will be an improvement for ~ $2K. You may take a step sideways, but I don't think you can do much better than the Droplet for under $2K. I also concur that trying silver cables or power cords may add the dynamics that you seek.
Cheers,
John
