Hi,
Go for 6 SE, it will sound brilliant. The 8 SE IS better, but they are both superlative. What's great about going down the Cyrus route is if you get the 6 SE and after a year or so, feel that you want a change, you can send your machine back to Cyrus and have it upgraded to the 8 SE and once that's done, if you want even more, you can add a PSX-R.
Sorry, I can't be of much use on the standmount recommendations.
