Bi-amping advice for M/L Aerius

These speakers have taken me through many upgrades and get better every time. I started with CJ PV10a and Sonograph sa125 amp. Then I swithched to Proceed amp with ARC LS-15 and upgraded cable to Transparent "super" balanced between pre and amp, single ended between cd (Sony 9000es) and pre and super bi-wire to the ML's. All of this of course was not done at the same time. Every upgrade was very noticeable through these speakers. Now I got the bug to upgrade to the next line of Transparent......this is killing me.

Actually an easy way to actively bi-amp your Aerius's is to add a sub woofer with its own amp and a high pass x-over that is worth a damn (Like the Velodyne FSR/HGS series of one from HSU). By rolling off the bottom end of the ML below 50-80 HZ, you will pick up a nice amount of headroom on both the main amp & MLs, add extension down to 20HZ, and considerably open up the soundstaging of the MLs to boot. A brand new Velodyne FSR-12 sub can be had for $800-900. You can get more options by going to an outboard active electronic x-over (Marchand or HSU). This allows you to expand your choice of subs to those that are excellent (REL for example) but don't have high pass filters built into their electronic x-overs.

Good advice 1953, I do agree with you. I heard the Marchland x-over is great and from what I seen on the vmps website. I'm looking at there subs now.
