Any experience with Ayre L5-Xe Power Conditioner?

I bought the L-5xe yesterday. Initial impression is very good. much quieter background, and no change in tonal balance.

How long would it take to burnt in the unit?

I have my Messenger preamp and C-5xe connected to the L-5xe, and really wouldn't be without it. However, I heard a slight negative effect when I had my MX-Rs running into the filter, so they now go directly into wall outlets. The 'table (actually the SOTA's PS/vacuum) runs into L-5xe outlets, but only for the sake of convenience (i.e. I can hear no difference vs. using a wall outlet).

I use an L-5 with my AX-7 and CX-7 (I think neither of them include the internal Ayre Conditioner). I posted a review on AA. In short, it made my system more resolved and liquid; a nice improvement.

My system uses the L5xe, with an Ayre power cord...for power for the KX-R, 3 MX-R...the D1xe and Meridian go to a different power conditioner...it seems to provide a benefit as to lowering the noise floor...but the most important thing I did was to have dedicated 20amp circuits run with over sized wire directly to my incoming power panel...keeping the digital units on one circuit and the analog stuff on another...AC noise, for me, is not an issue. So I reccomend the L5...but do the power line thing also...by the way I use top quality furtech AC sockets...and on all AC power cords.
