Re: SPD-S vs SPD-SX
The SX is a huge upgrade IMO, worth every penny. The big things are the USB connectivity with the wave manager and the built in storage. If you have a lot of samples you need load up, it's sooooo much faster with the wave manager- and you can drag and drop samples onto pads and create patches in no time. It also has twice as many trigger inputs and a built in click with a sub out so you can send click to in ears and not have it come in the mains. The original spds was great but SUCH a hassle to load samples and create patches on. That reason alone is worth getting the SX IMO.
