I was going to do a serious evaluation last night but then I had an emergency come-and-fix-my-Mac call from my mom. I did however, listen to part of a song with and without the unit. My impression was that the G2 made the sound tighter and more focused, with less bass. (is this what they call "taut" perhaps?) The stereo spread seemed narrower and the vocals seemed more centered. I stared at a lightbulb a bit this morning but didn't notice much difference. No, that wasn't my formal review, but just the overall impression I got. It seems to be the same effect I remembered from the first unit actually. I was glad that I was able to perceive what I thought was a difference and\or improvement, but I would not be inclined to purchase this item unless I made upgrades elsewhere.
What I really really really want to audition is the Furman IT-1220. I was going to rent one from Mars Music last time if they had one, but they went out of business the day I visited! Bad timing, aina? I am not willing to spend 1200 bucks on something unless I know it can kill my ground loops and filter out the grunge caused by other electronics in the house. I determined the hum induced in my Mackie HR-824's amp is caused by a humidifer running on the Low setting. If I switch it to High the hum on the Mackie is less, but still there. When I think of power conditioning it's those kind of problems I hope they will fix. But patching the DeZorel between either the Mackie or the humidifer did nothing. I dunno, maybe there is no cure for having cheap electronics running on the same line as your hifi gear.
How come there isn't more interest in battery powered stuff I wonder? I remember reading about some phono preamp that was battery powered, but the cool thing was that you didn't have to charge the batteries in some kind of separate thing, it just plugged into the wall and charged when necessary. Cool. From an ecological view I am not fond of non-rechargeable batteries (careless waste is a pet peeve of mine), but if they are self-sustaining that seems more logical.
