Palmer PAN 04

Very well built passive DI, sounds very good, transparent to me, or at least it's musical if there is any slight coloration. It's built like a tank, you can probably step on it (no guarantees though, I didn't try!). It feels like some Radial boxes I have in build quality, also good for stage work especially that the buttons are a bit protected by the frame that extends longer than the buttons reach in their out position. It's has some weight to it physically, so if you need 10 DIs for live and lug them around yourself, look for something a little lighter - I use this in the studio to a stage box and that works fine; the weight is a positive there so it stays in place nicely.

This DI sounds great. It isn't as transparent as a Radial J48, but it really sounds great. I often use it on Novation Bass Station 2 and it sounds better through this DI than it does through the J48 or directly to a line input of a console.
Even if it were a single channel DI, it would be still great for the price.
The connectors are also reliable.
The only downside is that the chassis isn't very well protected and the paint can start chipping off if you throw it around too much. It isn't bad, though. If you take care, it can certainly last for ages. Mine still looks like new.
