I am ordering a Bifrost to go with my WA2 and HD650's and had a question about the "uber" analog upgrade. Does the upgrade make the treble harsh or fatiguing in any way? I thought I read somewhere on here that it does and I dont really want that to be the case for me as my ears are a little sensitive to overly bright presentations in music.
 
Any input would be great!
 
Thanks!!

Not harsh or fatiguing to me, after listening to the upgrade most evenings for about a month.  Three things that I would recommend though:

• Give it at least 100 hours to burn in before judging it.
• I have head phones that are thought to be slightly soft on the high end (http://kenrockwell.com/audio/stax/sr-x-mark-3.htm), so take my opinion with a grain of salt.
• Read opinions here on head-fi and elsewhere, I think that most people do not find the upgrade fatiguing.

 
YMMV

I have never found the older non-Uber Bifrost or the Uber Bifrost fatiguing, and I'm experienced real fatigue in other setups so I know what to look for. The non-Uber Bifrost, at first blush, did have a bit of a lean toward the higher frequencies and some even described it as "bright," but after burn-in it mellowed out for most people (including me). The Uber I haven't found to be shifted toward the high frequencies at all, if anything it added more punch and heft to bass/lower frequencies versus the non-Uber Bifrost. I will say that I tend to enjoy a fair amount of treble/HF extension over mids and LF's, though, possibly more than most people, so I don't share the same issue/sensitivity as you.

Thanks for the opinions, I thought maybe more would chime in.
 
I am also considering the DacMagic and one from Peachtree.........  ugh.

Go for Bifrost non-uber first maybe?
 
Paired with Valhalla and HD 650 I don't experience it as overly bright. No harshness but more like just right.

I think I am gonna go for it with the upgrade, I hate the thought of not doing the upgrade just to spend more money to find out the difference later. lol.
