Got mine a few days ago..I do not have the Gungnir..currently using the bifrost.,& Lcd-2's,plus my new pair of He-6's.
All I can say,it is the most dynamic,strong,clear,detailed sound,,I could have imagined,or hoped for.
Simply amazing..
One of the strongest points is the bass,much deeper,that what I had from the Lyr.
Most of my music files are ..acoustic guitar,some rock,and mild jazz..all come through perfectly.
With the mjolnir,you hear details in the music,you never heard before,for example...people in the audience,coughing,musician,sliding their fingers across the fret board,musicians,inhaling & exhaling,while they perform...that kind of detail & clarity.
It is like siting in the front.. row of a concert hall.
It is definetly a,night & day experience.
I really loved my,Lyr/bifrost combo,& I was undecided about upgrading,but,man I'm glad I did.
I will miss the lyr,& all 35 pairs of tubes ,but sold most of them & glad I did
I e-mailed Jason at Schiit,to tell him my impressions ,& to thank him,and ask him a few questions about the Gungnir;
He wrote back,:
"Gungnir is a gigantic step up from Bifrost--I think you'd be very surprised how big a step up."
So,guess what my next purchase will be?
Anyone ,on the fence about the mjolnir...don't hesitate..just get it...it is one hell of an amp..
This amp ,will take you into audio heaven.the best upgrade ,I've made so far..
