I have a brand new VTL 5.5 I just got a few weeks ago, was looking to accomplish the same thing you are. SS and tube can be a very nice mix if done correctly. I matched my VTl with a Krell 2250 and they hold hands nicely, very nicely. In fact the VTL 5.5 is dollar for dollar one of the best Pre amp values on the market today. Not to mention it's a nice small company, and like joining up to a family one you buy one.
I don't know what you have for SS amp, and this does matter when considering a pre. But if you have something that is detailed, does bass well, and can be edgy (like a Krell) a VTL is a perfect match.
The other (lower priced) option you have is to mix in a Tubed line-stage for less money. But a Pre is the ultimate, and you will not regret buying a 5.5.
