The Lyr tube rolling thread begs to differ.
To address the OP, do you intend to purchase orthos down the track? If so, the Lyr is a no-brainer, especially for the price. If you're looking to just find the best synergy for the HD650 in a tube setup on a tighter budget, I'm sure there are cheaper options that also yield great results.
