Good Hi Fi system should produce enuogh bass without adding sub otherwise something is wrong with the speakers, amplification (not enough power ?) ,cables or the listening room.

itzhak1969,

Sorry I don`t agree. Even the biggest speakers like Focal Grand EM benefit from properly installed subs. Of course you need a fast sub that matches your mains.
Your statement may be somewhat correct if your listening room is very small but again then there are more reflection bass than a real pure bass.

Anyway the main topic here seems to be our beloved BO.
So I did a quick google on our mighty leader and enlightener Bo.
It seems that it`s not at all about MA. He has probably fallen in love in some some artifactial DSP surround. 
I will continue in my next post.

Your comment is perfect adding a sub is no more than addiction to artificial unnecessary extra bass .

Or

Maybe the amplification doesn’t have enuogh power to drive the MA, maybe the cables need ugrade or the listening room is very big I don’t now ....

The MA 500 should handle low frequencies properly without adding sub .

Long live our big leader and pathfinder Bo!

I use the Onkyo PR-SC5509 these days as a pre amp. With Audyssey Volume and EQ you can reveal details which are not there even with the best highend pre amp. I give you a few examples. Compared to the XP-20 you hear word endings on a sss, ttt of th so much more clear than with the XP-20 .

Now I need to push this.

Soooooo........... to all serious audiophiles!
2017 is a yeat of Tru-Fu coming and we all will be blessed and enlihtened.

A second coming of our big leader and the mysterious Onkyo DSP.

1. Evey serious audiophile must use Onkyo 5509 as a preamp and procces the signal through it`s messed up DSP to hear it`s artificial 3D  surround effects. It`s leading to real 3D sound that will go up to 8m behind the loudspeakers.

2. No room treatment or proper placement needed! All can be compensated through a messed up digital room correction programs.

Now I need to push this again.

itzhak1969,

No, No! The sub really helps but you need to take some time to install and blend it correctly. Today we have many subs that can act fast and can be integrated perfectly to top high-end systems.
