Parasound's new Halo integrated

What do you have now, and what improvements do you expect to get with the upgrade?

It's good that you listed your Rega. I haven't heard the model you have, but I've only seen positive comments on it. I suspect it would be an excellent sounding amp. One of the things you may want to consider if you upgrade to the Parasound, is that you won't be just getting more power. You'll be getting a different sounding amp. For me, at least, that's extremely important. And which amp is better is just personal preference. So my advice would be to demo the Parasound before you buy it. When you are replacing an amp as nice as the Rega, its much easier to make a mistake.
