For those who've moved from "vintage" to newer units

This is my first post on Audiogon, and I'm looking for additional thoughts to consider as I think about possible changes to my stereo system, the heart of which is a (fairly recently) recapped Kenwood L-0Cii and a Dynaco ST-70 (recapped, low gain VTA, and upgraded power supply). They feed a pair of EV Interface D series 2. It's a nice match and I have no real complaints about the sound at all. The Kenwood has a superb phono stage. 

I'm considering a change for the sake of simplicity. I'd like to consolidate space and perhaps move to a newer integrated amp (hybrid or tube) so I don't have to worry about have old gear serviced. What I don't won't to sacrifice is good sound on a tight budget. I'm not in a position to audition new pieces, so it's a gamble. 

If any of you have moved to newer gear after owning/using units similar to mine, I'd love to hear about your experiences. Any regrets? Are you happy with the change? Advice for this audio layman?
