Something that's worked well for me in the past is to secure at least 1 good offer - compensation you feel comfortable with, recognizable brand, but still an offer you're willing to walk away from - and then give notice.
Then, after leaving, spend additional time (up to 4 weeks) interviewing with all the other companies you want to. Keep in mind that many companies offer a sign-on bonus, and using it to cover this in-between time is high-return, likely more so than buying a new car/vacation/entertainment system.
You can be upfront about this break in your interview loops - "I'm no longer working at company X, but I have a very competitive offer from company Y and considering several other ones." There's no guarantee you'll be able to keep all the offers you receive (many of them will explode), but you should have a steady pipeline.
Whenever you feel comfortable, you can exit the pipeline, and begin negotiation with the outstanding offers you have. Last I did this, I went onsite ~15 times among even more interview loops.
