My advice would be to keep them PV5 until you try a SS receiver or pre-amp/processor. If you keep the 2200 that will help keep the tube sound.
I would also consider NAD (like the 757, 775 or 787). It does not have the bells and whistles of the Asian brands, but it is more musical than many of them. Spearit Sound has good deals on NAD. With the receiver, you can use the pre-outs for the L/R and use the internal amps for the center and surround. Interestingly, since receivers have much higher volumes than pre-amp/processors, the full receivers are less expensive that a comparable pre-amp for similar quality. Then you can use the amps as needed. You also have a wider selection of receivers to choose from.
To get an AV8801 for around $2K you probably need to go the ebay route.
Good luck.
