Bifrost multibit vs gungnir multibit


Please redirect me if this has been discussed elsewhere, but I haven’t found it if it’s so. Has anyone experience or knowledge of the advantages of the Schiit Gungnir multibit over the Bifrost multibit other than the propriety clock in the Gungnir?  A friend lent me his Modi multibit, and I became interested in possibly getting one of the Schiit DACs. The Yiggy is beyond what I want to spend, besides the reviews I’ve read here indicating that the Gungnir is a bit mellower sounding, which is more to my preference. Here’s the rig for background:
Yamaha CD-s2100 Sacd player 
Sonic Frontiers Line-1 preamp
Parasound JC-1 monos
Triangle Volante 260 speakers
B&W ASW650 subwoofer

i also have an Arcam rDac that I’ve read on threads here may have a “multibit-like” sound, and I’m doing comparisons this evening with the Sabre DAC in the Yamaha. So far the Sabre is winning, but I didn’t compare the rDac with the Modi when I had it.  I hadn’t known at the time about the possible similarities between the two DACs. 
Any info opinions and or experiences welcome, thanks in advance,

Congrats!
I am using the Gungnir (non-multibit) while my Ayre Codex is repaired.
It is close, but lacking the finesse of the Codex.
I would suspect that upgrading to multibit would bring it pretty close, if not to the Ayre Codex level.
Also, keep in mind that DAC's need to be left on in order for them to sound the best. I suspect your Gungy will keep improving with time.

Thanks Bob, yes, leaving the Gungnir on 24/7, but it’s only been a day so far. I do like it a lot, but I haven’t heard the Ayre so I don’t have means for comparison. Unfortunately, the one store in Chicagoland that I knew was an Ayre dealer recently closed its doors, so I’m hoping to hear more comparisons at Axpona this year. Very sorry to see Audio Consultants go. Hope the Codex gets well,

I know this thread is old but I'm presently considering these two DACs.  (I've got the DAC bug.  I just bought the Ayre Codex and now I want to compare it to one of these). 

I'm very sensitive to highs and just returned a Topping D70 because it was just a bit too "clinical?" to me.  

Appreciate any thoughts on the differences between these two.  
@soundchasr,
Good choice on the Codex.
It performs well above it's price.
To compare it with a similar priced unit, I would suggest a Schiit Yggy.

But, to be honest, the folks at Ayre just offered the QB-9 with Twenty upgrade. They feel it is a significant upgrade over the Codex.
I found a used QB-9 and had it upgraded ($1500). I still have to put into the system, so I can't claim it sounds better, but knowing Ayre, it will.

Another factor in sound reproduction are cables.
What are you currently using?

@soundchasr

Did you ever compare the Ayre Codex to any of the Schiit dacs?  What were the results?
