Actually the PP SE debate wasn't what I had in mind. There are great versions of both. The question is(and the reply you gave that you should build around your favorite speakers came closest) is this. Obviously there is always another step on the ladder; but after all this is about music and sound. What I am interested in knowing is which amp caused you to sit up and say thats it! And if that never occurred then I would imagine then this is about the search for that. So; is it an endless quest; or does there exist a mark to hit. Should you hit that mark; do you stop? If you were to find a build that sounded exactly how you wanted; what would be next? Or is it building for the sake of creating with no agenda other than the search for what works and the personal urge to explore and finding how close to the performance edge you can get.
