Have run 2.3's with a McIntosh MC602 with excellent results and absolutely no lack of power. A new old stock MC602 is cheaper than a new MC402. The MC602 uses bulbs and there is an LED kit available and can be installed at the time of purchase-which is what I did.
If you move up the Thiel line in the future the MC602 will power any model. Call or email Ernie at Audio Classics for info on the NOS MC602.
