Of course, but would asking 25-30% more for new salary base be considered too high?
You tell me -- I don't know where your compensation ranks for someone of your knowledge and experience (I don't need to know the number, but would you say it is fair currently?). If your current salary+bonus is fair compensation for your experience level, why leave unless you can get more money, perks, or benefits? Also, let me be clear -- do NOT tell them what you are currently making if they ask. What you currently make is irrelevant and can only be used against you -- no good can possibly come by revealing it (it is none of their business). What IS relevant is what you would like to make, which is entirely reasonable to tell them.
I was pressured to interview with a local company a few months ago and I thought "Aw, what the hell -- it is good interview practice if nothing else." It was a small company and I was pretty sure they wouldn't even come close to my pay, but I thought that maybe they'd have some sweet benefits or perks. I was wrong -- first of all, they talked about how everyone got 2 weeks of vacation to start. I told them that 2 weeks of vacation was a deal breaker and I wouldn't consider less than 3. They then showed me some book they created showing all the positions in the company, salary bands for each position, etc. The position they wanted me for would've been a 60% pay cut. I just laughed, thanked them for their time, and left despite their "sales job" of telling me how awesome their company was, etc. That's also when I found out that they only did $5 million in business per year, which is also too small to be worth my time.

The point of this story is to illustrate that you need to know exactly what you want and what you will settle for when interviewing.
