Pete just called around to my place today...mainly to collect/deliver a few bits ,as he was in the district anyway.....but he had also  brought  the " blue light " device with him.  I was interested to give it a try.

We cranked up a cd fro my Bonnie Raitt collection (USA/folky/bluesy) which I've listened to for many years, after giving the gadget its  2 mins warm up time.  Knowing Petes enthusiasm for the thing I had to admit that I wasn't certain of any dynamic improvement.  Maybe a little extra definition?  Not conclusive though. 

As a test, Pete unplugged it whist we were listening .......there WAS  a difference at this point.....for me slight loss in warmth in presenatation.  SOMETHING happened. 

I personally would n't pay £700 for the kit (even if i had £700 , which i don't).....but I did like its effect.

Pete reckoned he was hearin an improvement in soundstage.  Maybe I've been playing with different bits too much this last week, maybe my cold has stuffed my ears...I didn't pick that up.  I do know Pete well enough now to know he has got an ear for this stuff (when mine's had enough), which is mainly why my system, under his guidence, is  beginning to sound ok (with a presentation to rival my brothers MF/Spendor floorstander  combo). So if Pete said the blue light gadget was improving the sound satge , as far as i'm concerned , it probably was.
