I've tried all the taps and definately prefer the 8 Ohm. In my system the 4 Ohm limits the dynamics, bass..everything is flat sounding. The 16 Ohm is a bit bright..8 Ohm perfect! I listen exclusively in UL mode. The Triode less coherent and < dynamic overall.
Just biased some Re-Issue Tung Sol 6550's and they sound very good indeed. Bass is not quite as prodigious as the stock tube.. being somewhat less focused, but the mids are more lush with a nicer top end IMO.. A Very listenable tube/ Im sure they need to break-in for a time.
