How to tweak a system.

do you mean how to change the "sound" of your stereo system with passive components ?

do you mean how to minimize inherent but audible imperfections of a component, without replacing that component ?

there are many anti resonant devices (materials) which can affect the performance of a component. is this what you mean by tweaking ?

Actually, Mrtennis(I bet I can guess your favorite sport?), I'm from the old school that had turntables and all the cartridge and arm adjustments. Turntables had springs and feet and some had motor adjustments. We still have speaker placement, though. Thanks for the XLO recommendation,?(if I go to see your moniker, I lose this letter. I actually have 6 different anti resonant devices, but I've not compared them, per se. I do want to mention two tweaks that are no brainers. One(from Naim) is to separate power cords from signal cords. The second is to raise speaker wire and interconnects at least 8 inches from the floor(from Mapleshade). I couldn't raise my speaker wire that high, but I used three 16 ounce styrofoam cups(thank you Dollar Tree) at various places to raise my signal cables from my rug.

I've got lots to say about speaker placement, but what I might say will depend on

1)Type of speakers,

2) Size of room

3)dimensions,

4)location of walls and openings and windows,

5)What are your sonic priorities,

6)What limitations do you have regarding optimum speaker and listening position placement, i.e. is this a dedicated audio room or is it a dual use room to be shared with others.

And since I'm asking questions have you done any research into the subject of room acoustics etc? Have you read the various formula's by Cardas, Audio Physic's, Dunlavy, or looked at the Cara program on the Rives site. There is already a lot in print in in Audiogon and AudioAsylum archives to keep you busy reading for a long time. Just depends on how serious you are. It's time consuming and can be a frustrating task when you try to maximize speaker placement and room acoustics. But, its worth the effort!

hi mmakshak:

my favorite sport is football, i.e, to americans, the sport would be soccer.

i watch the english premier league games whenever i can. years ago, i coached junior boys, ages 10 to 12.

it's a wonderful sport requiring athleticism, ball handling skill and aerobic fitness.

The beauty of the XLO Test CD Track 3 (out-of-phase) is that set up of speakers using Track 3 is independent of type of speakers, room dimensions, use of room acoustic treatments such as tube traps, location of windows, and openings to other rooms.

Virtually all other methods of speaker set up are generalizations that may or may not hold true for a particular system/room. Track 3 of XLO Test CD allows audibility of speaker position to within about 0.5 inch in a well tuned system.

Cheers, GK
