Looking for advice on 2 Channel system

As above, staying with BAT for a preamp sounds like a good idea. For speakers I would highly recommend the Infinity Prelude MTSs. Top to bottom, they are the most neutral, well rounded speaker I have heard near their price. They offer a built in sub system that easily lets you optimize bass (in your room!) that extends down to an honest 20Hz. They integrate seamlessly to the upper range drivers, which are ‘panel like’ in speed and imaging (and they ain‘t bad looking either). I also own a pair of Apogee Mini Grands. While they can play jazz and classical phenomenally well, they really can’t play rock to the same standard. That’s why I love the Prelude MTSs, they really can do it all. Something to consider since you …< Listen to rock, jazz, classical in that order>.

Have fun...IMHO two channel, done right, is the way to go.

I hear so many good things abount the Adcom GFP-750, and it also has a very modest price tag. As far as speakers go, Magnepans, JM Lab or if you feel like trying something different, try http://tyleracoustics.home.mindspring.com/

With a $10000 budget, I bet you'll have a sweet sounding system. Spend a little on a balanced line conditioner for best performance.

If you sell the VK-500, that would give you a $12,500 budget.

For that amount you could purchase the following used items:

McCormack DNA-2 Rev A amp at $4200. Far superior sonically when compared to the VK-500 (I used to own a VK-500 and now own a DNA-2 LAE).

Aerial Acoustic Model 10T speakers at $4000 in a nice rosewood finish. Excellent full rang speaker.

Placette active preamp at $4000.

For those three items, you're looking at about $20k retail and $12,200 used. And assuming you have a good source cd or lp player, you'd have a system with transparency and detail and dynamics where you'd pull out every old lp and cd to hear them in a way you'd never thought possible.

-IMO
