Do I need BOTH amp and pre to be sonic holography?

The phrase was something like 'Interaural Crosstalk Delay'.......

In my (now ancient) messing with backchannel phased speakers (no delay) I was able to get great results by using a 2nd amp and wiring a pair of speakers IN SERIES between positive poles. Live recordings were LIVE.
In those days the system was a pair of JBL4311s in front w/ an SAE power amp and a pair of RSL3600 Studio Monitors and a Kenwood KA7100.

I STOLE the idea from the then popular DynaQuad circuits I saw.

Get a c-9, but get the manual for speaker set up. If you like the sound, you won't want to go back.

Wow. The depth of knowledge, and generous willingness to share it, is stunning and very much appreciated. Obviously I am a neophyte to this hobby, but learning as I go along with limited finances at this point, from research, trail and error, and in no small way from quite helpful people such as yourselves.
Sorry, I did realize I needed the pre for holography, but was interested in the value of the concept. Thank you Ghost, I shall start search for upgrading preamp first, as affordably as I can. Perhaps the Mc C35 I mentioned.

I know I sound like a stuck record, but nothing can replace auditioning equipment at a "high end emporium". No amount of reading post's written by some of the smartest people I have ever encountered will tell you what true "high end" sounds like.

You have to make that trip to a "high end emporium". Once the sound get's stamped on your brain, you'll know when you're getting it right.

It's really incorrect to say the name meant nothing. The sonic holography circuit is first patented, which means it has to do something. What it actually does is send a little of the left channel signal to the right channel, but 180 degrees out of phase. It also adds a little of the right channel to the left channel but 180 degrees out of phase. In this way, it helps to couple the left speaker to the left ear, the right speaker to the right ear, and the out of phase signals make that happen. Impressive on the right recordings, awful on gimmicky recordings. The C-6 preamp will work with any amplifier.
