OK, it's expensive. But mine, 2 years on, brings out the best in my HD800s, T1s, and PS1000s.
All of these phones are transformed into greatness with the B52. I'm not kidding.
I read about the shortcomings of these headphones and agree with them on other amps, but somehow
the B52 tames brightness, uncontrolled bass, traces of grain, brittle midranges, lack of pace/timing,
whatever. (And not through big coloration, either, as the character of each of the phones is preserved loud and clear.)
Although its sounds trite, the B52 takes all these phones to a new level and beyond.
I don't say this lightly and I have nothing to gain from this (I'll never sell mine).
I've been thru other amps from Headroom, Stax (with Omegas),
Luxman, and even RSA itself and own a big Rudistor (which I really like, but the B52 is better).
But, instead of churning thru lots of phones and amps, it would have been cheaper for me to just bite the bullet
and buy a B52 first and one set of top-end phones and leave it at that.
I been playing with headphone systems seriously for decades and never found happiness, but I really think
if you can live with tubes, the B52 can stop any thought of upgrade-itis for amps AND phones for good
and save money in the long run.
I guess it's the price that keeps it from being mentioned, and maybe the owners are just so happy they don't
need to ask questions here anymore. (I wish owners would chime in, because a product like this really deserves some
