erick,
yo tengo MBHO's. Tengo el 603a con los ka200n capsulo's.
Me gusta los MBHO's mucho. Yo Compro' los MBHOs en febrero de 2001.
Recuerdo muchos conciertos differentes con los MBHOs, y esta' mi favorito de los microphones... especialmente para el dinero.
(please excuse my spanish, i only took 3 years in HS and 1 year in college)
Get the 603A's. There seems to be a slight difference in frequency response when using the 648's with some of the more expensive (Large diaphragm) capsules like the ka1000 and KA1100 mics.... but there will be NO difference in frequency response when using the ka200n (cardioid) capsules with the 603a versus the 648A.
In the case of 648a/ka1000 versus 603a/ka1000, you will get better response using the 648's.
But for the extra money, i don't know that it's worth it. I would suggest sticking with the
603a/ka200n system... and possibly consider buying a 2nd pair of capsules for other situations (hypercardioid, or Omni).... but the ka200n will remain the most versatile of the capsules in the MBHO family.
Hope this helps
and welcome to team MBHO!!!!!
adio's
