Luis,
If you read through the previous posts, you'll see that the majority of those who upgraded to the 2.1 version actually liked it better, so that puts me in the minority, and there's a good probability that you might prefer the new version more. It could be just the way my system is put together that makes me prefer the older 2.0 version. The Fusion Impulse power cord is a perfect compliment for my preamp, however, this is an Audio Horizons thread and Joseph has his own power cord line. I don't want to take away from that.( I still use the original Premium power cord version in my system). I think we discussed this in a phone call a while back where we both preferred the less expensive model, the Premium, to the Transparency model.
