it's a noticeable upgrade from Type 4 to CV-4, the old style without the batteries...

..good choice to stick to one manufacturing philosophy.  That way you get the full advantage of what the designer had in mind.

AQ seems to be pretty good when it comes to upgrading- Meaning that each step up from a model grade gives you enhanced listening improvement.
Can you tell us what equipment your connecting?

if you are considering the Rocket Series- go for the "88" model.

Happy Listening!

Thanks for replies!I have decided to move my xpa 1 s in the basement and just run xpa 5 with my integra 80.3 and Thiel 3.7 for main system.By using only xpa 5 as  only amp I can upgrade speaker wires without cutting them up,as I had to for the ultra wide posts on the xpa 1 s.(why they made posts that wide I don't know?).I really didn't hear enough difference between xpa 1 and xpa 5 to leave monos in main system,family is happier with simpilar system also.My 805 speakers do sound better with the xpa 1s though.That move was more of an upgrade.
