Right ... the BHA-1 has a very calm demeanor about its sound, for a SS amp, and plenty of power. Nice being at my end-game.
Here's a fun fact about the BHA-1. I bought mine new from Moon-Audio, a few years back, for $1,495. Now they want $2,195.
The only fault I find with the HD800 -- they are very picky about upstream gear and music quality.
Without a proper DAC and amp, they will always sound bright ... to the point of being unlistenable.
That may be what happened to
@allhifi.
I think David called this behavior "amp picky." He is very eloquent.
My first amps - Schiit Audio's Asgard and Mjolnir1 - were too bright.
The Sennheiser HDVA600, designed for HD800, was better but was too tame - missing the oomph factor.
The Schiit Gungnir D/S DAC was also quite bright. The Gungnir MB is not ... it's worlds better than the D/S version, IMO.
It would be interesting to test the HD800 with the Gumby and Asgard or Mjolnir1 amps, but they are long gone.
In addition, poorly-produced music sounds like ass. MP3, even 320kbps, doesn't work ... needs to be FLAC/ALAC or better.
That's (one reason) why I don't stream music. Maybe when Qobuz is fully deployed in the US.
It's the old garbage in = garbage out scenario that all process engineers and computer coders understand.
The cool thing is ... when you hit the right combination, you know it immediately
Prosit,

ps. There is much more information on Head-Fi about how to make the HD800 work.
