I bought this one one when first came out, but just had a chance to give it a try. There are plenty of great sounds for punk and hard rock in this pack. There were also a few really nice cleans included.
Here's a quick clip messing around with a few of these profiles. LRS Mars 2500 OV30 10 to the left and LRS Mars 2500 OV30 37 to the right.
In most cases, Soundcloud uses a bandwidth of only 128 kbps. As a result, what you hear isn't free of artefacts, especially the high end. For critical listening and also product comparison, please keep that in mind. Users who setup a comparison should use linear wave files and supply dropbox links.
Are you planning on profiling this when any other speakers?
