Thinking of putting to rest ESL63 for Harbeth M30.

Any thoughts of putting to rest my ESL63 USA monitor for a pair of Harbeth M30.1 or possibly a comparable Proac? Would be driven by Paoli SOB's, a D150 or a D79. Listen mostly to classical music.... Thanks
I swapped a pair of 57s for Spendor SP2/2 years ago. The first thing I noticed was the veil that appeared. I love the Spendors and still run them on another rig. However, I never forgot how good the Quads were. I ended up buying another pair of 57s and they are every bit as awesome as I remembered.
I still remember the first time I heard the 63s can't say that about very many speakers
I went from ProAc Response 2.5 to Harbeth C7-ES3. But keep the Quads...
