Amp - preamp or integrated


This topic has appeared in the past but I like to hear audiophile suggestions specially if they honest. I currently have the Rogue Chronus Magnum II. With Vandersteen 2 sig. Soon I will sell the house and will have some extra $ for upgrades. I have 4 questions:

Is the amp/ pre amp a better way to go than integrated? Two choices Rogue and Parasound.
Is the mono blocks / preamp an even better way to go?
If I decide to go with mono blocks, due budget considerations , I will be looking at used or an small company/audio engineer where I can keep the cost under 3000. If I go with a small company product, how do I know it is a good quality prod. Vs big companies like Rogue etc?

All your comments to all or any of my questions is highly appreciated. Thanks

If one wants to simplify their system then go with an integrated, there are many available that sound very good.
Otherwise separates would be the way to go.
Technictly speaking good monoblocks should sound better however I have not been able to detect a difference in the sound of music using monoblocks vs a two chanal amp.
One more thought to add, I know many audiophiles (myself included) that have gone the entire gamut of what you have asked and have made changes in their systems simply to try something different, the need to experiment or perhaps boredom.
Thanks lak3497. Your response make sense. I know of some good integrated amp but very expensive. I will probably go toward amp/ pre amp .
Pardon my ignorance, but how can I connect any sub(rythmik or REL) to the Rogue CM if there is no sub amplification. I dont understand what is to go line level?
If you buy a sub that's capable and has speaker level inputs (binding posts) then you connect it to your Rogue's speakers terminals along with your main speakers.  Simple way is to use whatever terminal type that is the opposite of your main speaker cables.  I use spades for the mains and bananas for the subs.
