Use this song if you are doing an A/B with Preamps


Sixty Years On by Elton John.
A Demanding song with Orchestra, and a Lot of Head Room.
Played loud, it reveals Intense Strings and Swells
Whichever Preamp does That best, Wins !
The other one goes up for sale, period.

Cheers all !

 I'm an Elton John fan too,but find the recordings too compressed unfortunately:( I still enjoy them though.The other day I really wanted to hear some Blood Sweat and Tears tunes.Spinning Wheel is a very dynamic song!I'd sort of forgotten about them.Lots of brass,drums,bass,and that powerful voice of course:)
There are many recordings I use for evaluating gear, but I particularly like using Stevie Ray Vaughn's " Tin Pan Alley " to do any equipment evaluations ( studio version from the album " Couldn't Stand the Weather " ). Enjoy ! MrD. 
@stringreen - I just saw the Elton John (farewell tour). Was not disappointed.
