Can you describe its sound signature and how is it better than mullards and russians?
Its the RCA square coil 6AK5.
In the AKG K702 Annies, they bring out more warmth (I like warmer sounds),
and makes the gave the highs a sparkle that gave it even more musicality (the K702 Annies was know for this already),
better than the Russian which had a overpowering bass and the Mullards that did not have such a refined high.
The HD650 was similar,
the bass was not as overpowering on the RCA compared to the Rissian,
yet it was still relatively tight compared to the Russians and Mullards.
But the Mullard did have a better mid on HD650,
but the Mullard sounded a bit too thick on the HD650 overall.
Loving my RCAs!!!!
What other headphones would you recommend for the Pan Am other than what I have or LCDs and Beyers?
I am keen to know since I have to return my HD650 soon,
and want another pair of HP to mix it up with my K702 annies.
I have some French RTC and SYLVANIA's coming in next week as well.
Will post on here as well if they are anything special.
