Yes...we have experimented both ways and actually run it both ways on different sets up we have.
For our setups...again, this is for our specific setups. We run Qol behind the preamp in our higher end room with Cary FE211s tube amps and in front of the preamp in our more affordable setup with a Cary 200.2 solid state amp.
There are many reasons as to why one may feel it sounds better in one position or the other. Some reasoning may be scientific, some may be physiological, and others mental but the reason an audiophile should place it in one place or another should be governed by what makes your ears happy...."Listen to your Ears!"
