OK, long time since I've been here, but always said that if a balanced CLAS came out I would revisit the idea of a 'portable' setup. I'm currently using a iPod 160gb > Zo2 > Unique Melody Merlins. I have previously had the Fostex HP-P1 (wasn't really to my liking) and a CLAS+RSA SR-71B with balanced cable, this was my favourite setup, and regretted selling it for the HP-P1. Now that you know a little history, I'll let you know what I'm looking for, I'm a basshead, there's no 2 ways about it, I like a lot of bass, but I like it to be clean and not muddy which is what lead me down this path in the first place. Now my current setup gives me the bass adjustablility I'm looking for, but none of the other features that I miss about the CLAS+SR-71B setup. So what I'm asking, does the CLAS-db + Rx MK3_B setup have a range of bass from very subtle (pot all the way down) to outrageously over the top "Who would listen to this much bass!" levels (pot all the way up)? Or is it more of a very subtle (pot all the way down) to "What a respectable person may listen to" (pot all the way up). I'm not saying that I'll turn it up that high, just that I would like the option to set as much as I want. And does it compare soundstage and presentation wise to the SR71B. Would be looking to use this with 320kb/s streaming through USB on the PC at work, and Apple Lossless through the iPod. Hopefully I've covered everything you need provide me with some advice. Cheers.
