Welcome, Marc!
Selling all your gear is rough, but think of it as a spring cleaning. You can get much better quality components for less money in many cases. Unless that is you sold a bunch of really hard to find shit like Vintage Neve preamps, a Jupiter 8, etc.
But seriously, it amazes me at what is available in the pro-sumer price bracket as compared to 3 years ago. I own a KC and that's it for synth hardware. But I have a ton of guitars, amps, mics, and a slew of soft synths by now. My only interface is a Mackie Onyx Satellite, and a Maya 44 PCI soundcard I use for digital DJ work. So the hell with it, buy all new shit! Yeah!!!
