@verdantaudio I'm going to dig a little into this and hope you could fill in a few gaps. I would love to compare many of these permutations and wish I lived closer to your location. Appreciate your posting here as always! - I would state 10% of the reason I got a Weiss 501 was based on some of your listening comments.
1. What software do you want to use? If you like Roon, this is not close. The K22 is the superior device. If you are not a Roon user or actively don't want Roon, then also, this is not close. The Pulsar is the better device. Sense is excellent
For my current system configuration with my K50, and most on Antipodes forum concur, that squeeze is the most sonically superior software option for well-recorded material. I do have some "brighter and thinner" tracks I prefer via Roon, and I confess I still listen to Roon 90% of the time due to the their far superior UI. You didn't mention squeeze, or Jplay, just wanted to confirm you have listened with other softwares; I have not heard sense or any Innous so I cannot comment, but I feel if someone were comparing "best to best" squeeze should be employed on the Antipodes.
2. Outputs matter and you are running a Bricasti device. If you have the network card in the Bricasti, I would argue a K41 running Roon or Audirvana would be top performer as ethernet in is best with Bricasti.
I have heard the Bricasti player/renderer is very good. I recently read of one Bricasti user with a K22 who demoed the addition of a K41, and the short is he is keeping the K41.
Curious if you could give some comparisons of a K41 into a Bricasti using its player vs. K41 into K22 player > Bricasti?
The Grimm is nice but I found did not outperform the Antipodes running Roon side by side. They seemed VERY similar. Antipodes has a slightly softer sound than Grimm but that was only noticeable difference to me. That said, I have heard that Grimm is at its very best with HQ Player enabled in Roon. I did not test this and have no POV on that.
Was this Grimm MU1 vs. K50? (or both K41/K22 which is the same as K50) or one half of a K50?
Which converter was used?
