NEEDED!!! Bi Amp Pros out there that can give me some advice

Ive never Bi Amp'd before and I would like to try it out. I want to avoid costly mistakes so any advice would be greatly appreciated.

Aragon 8008 bb would keep for the lows
Pass Labs Aleph 5 Amp looking to buy for the highs
Dunlavy SC 3's
PS Audio Perfect wave DAC no longer using a preamp
HSU ULS 15's sealed in Stereo two of em 
Tice Power block signature.


The 8008 BB is 200 at 8 ohms and the Dunlavys are 5.5 nom. The Aleph is rated at 60 wpc at 8 and 90 at 4. So I guess Id be running around 70 wpc with the PASS at 5.5 non load. Since Im running XLR out I would either have to y split the XLR's outta the PS Audio or use concurrently with RCA's that the PS audio will do. but I know that changes things on output impedance. So Im hoping some of ya guys been down this path and will help me out. Thanks in advance for any feedback

Yer a lucky feller clio! I still come to the Bay Area occasionally (my Cupertino High School 50th anniversary get together is next month!), and plan on making it to Roger's place to hear his direct-drive ESL's when I do. Sounds like a "done" system to me!

@clio09, really interesting to hear you are using a quad of 8" woofers with your Quads. Did you go sealed, or ported? If sealed, about a 1 cu.ft. box? I’ll bet it’s the same woofer Roger uses in his Music Reference ESL’s (which I’m dying to hear), ay? Ain’t it great to have Roger posting on AudiogoN of late? I REALLY miss his AudioCircle Forum (which can still be accessed).

By the way, Rythmik Audio and GR Research now offer an 8" model of their OB/Dipole Sub, which is the same as the 12" model but with less output. Great with planar speakers, of course. I have no doubt four 8’s is better than two 12’s, for the well-known reasons. Better to deal with bass modes acoustically than electronically! ---Eric.
