Congrats Sal!
The XP-20 needs 5 days of warm up to sounds at their best.If you can, change the umbilical powercord by a Revelation Audio Labs Passage Cryo Silver Reference DB-25 umbilical....is one of the best upgrades i ever done in my system!
If you are thinking in ceraballs think in a couple of HRS DPX damping plates too, maybe Ivan can help you with this
Enjoy this beauty, really sounds amazing!
