Integrated to match Von Schweikert VR-2


I'm a total neophyte with Von Schweikert VR-2s currently using NAD C541i and C320 BEE,looking to upgrade. Any thoughts on an integrated compatible with VR-2s? I'm looking to spend not more than $1500 and thinking of a Portal Panache demo. Thanks in advance to any responders.

Thanks for the responses - that (a source) may be what I need. I was noticing that some CDs have some jagged high end and others sound compressed and flat. I think the VR2s aren't particularly warm and fuzzy, I think I want to hear more depth, definition, and nuance (like who doesn't?). I thought the amp might give me more of those qualities - you're suggesting an upgraded source would be a better approach?

I'm running my VR2s with a vintage EICO all tube amp and the new Rotel 1072 cdp. It all took forever to break-in but is very musical now.
