How important is it for you to attain a holographic image?

I think it is extremely important. I think most recording artists (vs ‘live performers) intentionally work to create excellent holographic images.

...Hendrix, Pink Floyd, NIN. 

My system will put sounds in your head, behind your head, right next to your ear and sometimes 12 feet away from one of the speakers. 

Wicked cool.

As to room treatments and room corrections....

I have a concrete carpeted floor with another thick throw rug over that. I have some cheap rice papered changing screens and some ‘mass’ in my corners but those are my only room treatments. 

I found that that once I had proper power going to my woofers and very non-tube-like tube amp for my mids and highs, I no longer needed room correction or room treatments beyond what I have already listed. Everything just worked the way it should.

A high current, high dampening amp for your low end is a must. I still have ‘dance club’ bass but it is tuneful, fast, never bloated and it does not interfere with mids or highs. It just takes your breath away sometimes....

I am using Infinity Kappa 8 speaker. A very rare tube amp for my mids and highs and a BAT VK-500 for my low end. The VK-500 with BATPAK is just crazy good! 

Everyone should enjoy a good holographic setup. It’s like magic!

“Harmonic envelope” is a very good explanation of sound....almost holographic. 

@pwhinson I don’t doubt your friends JBL m2 setup sounds amazing....

many people on this site would regard that system as ‘substandard’ or ‘not worthy’ of comment, but I have a feeling it works great.

i have been playing with Crown XLS 1500 and 1502 class d amplifiers.  They are meant for sound reinforcement and/or live gigs. They have internal crossovers and can produce some serious watts!  And they are super quiet, no buzzing or humming, and no heat. You can easily afford them and the fans never come on. At one point in a bi-amp setup I was using four of them in mono and throwing a combined 6000watts at my Infinity Kappas. The Crown XLS are great on the mids and highs—tube like, holographic—but for the lows they don’t have the dampening factor to stop the absolutely insanely designed lowend of the Infinity Kappas.

Honest I think the Crown XLS 1500 amps are very nice. 

Try finding a pair of JBL 4408’s or 4406’s and use a Crown or two to drive them. You can get holography in style and on the cheap!

@bsimpson Good call!

Plus some of us out here are trying to recreate what the artist(s) intended when they were in the studio mixing the album. 

Hendrix can only be fully appreciated in a system that produces holographic imaging. And I am not exaggerating.
