Upgrade from 220pro CI to 250pro CI or 440pro CI

[Gerronwithit]

I also upgraded from the 250 Pro to the 1000 Pro which results in a much more open, detailed  and expansive sound all produced without any effort being put on the amplifier ie you can listen comfortably at lower volumes without feeling a loss of detail or urge to crank up the volume unnecessarily. I defy anyone living in a normal house stretching a 1000 anywhere near its limit. It also produces, to my ears, a less brittle sound than the 250, a sound that does not fatigue after a limited period of time. 

At each upgrade of my systems, I have looked for more clarity, precision and detail that I have craved since my first mono records way back in the ‘60s. The 1000 delivers all of this in spades.
