So far, Bugle boy tube (1960) and orangle label a frame sounds good. It's first for me to get tube instrument so it sounds warm and tubby.
with my hd800, it sounds more alive. I felt more body.
with asgard I did really felt asgard has power, with Valhalla I felt sudden power from the amp. That doesn't mean Asgard is bad, I love this amp, therefore I can't sell it.
Also, Asgard loves my lcd2. Maybe near future I'll just get the Lyr.
(I have to address you as that with your screen name)
Please don't misunderstand. My knowledge and experience with the Valhalla is Zero.
The Valhalla is probably a great amp, just entirely different.
Valhalla is all tube, Lyr is a hybrid tube/ss
I asked because I was concerned that I might represent the OG's as good for either amp.
I don't know.
