I don't know how it compares to the Ref 3 and 5 but it has transformed what I thought was possible in audio.
Here is what you should do to prepare and get the most out of the Dude.
Get footers as it does not come with any. I suggest a Sistrum stand to go under it. They work great under the Dude.
My second choice would be large brass cones - 3 of them.
Now buy some good 6sn7 tubes - 2 of them.I suggest Marconi black base NOS for $75 or so.They are the best I have heard in the Dude.
Last, please allow for burn in. At least 150 hours.
Enjoy
