I've had the A3s for 14 months and they continue to amaze me. The break-in is very long with the Magicos and has been continuing to get better with time.
The last guy that came over to listen was serious in wanting to know where my sub was hiding? I asked the same question the first time I heard them at the store during the demo. "No sub" was the answer to the question in both cases.
Be prepared to possibly make changes to your power source with the Magicos. I'll be installing a different amp for the third time and upgrading the preamp since owning them. They're a fussy mistress but the pleasure is worth all of the extra expense.
