Cheap tweaks...What would YOU reccomend?

vansevers and tweakaudio has tons of tweaks on their web

I've done two cheap tweaks that dramatically improved my system lately.

1) elevating my amp by placing a phone book beneath it.
-There is a night and day difference in bass extension. The bass is flat before the presence of the phone book. After, the bass is more deeper, controlled and permeates the room in an almost waves like manner.

2) spent $40 bucks purchasing 2 sheets of Dynamat Extreme from Carmedia1.com and tacked it on the bottom of my shelves. This transformed my shelves from a "scat scat" to a "thonk thonk" when knocking on it. The aural improvement is equivalent to swapping to slightly higher end power cords in the digital front ends.
-The highs and "digital" harshness is tamed a few degrees. Before, the highs hurt my ears if I played over the "55" setting on my digital preamp for over ten minutes. After, I can play up to "65" without ear fatigue.

what was in the cup?

No one I've shared this with has taken this seriously.

If you have two pairs of speak cables, one copper and one silver, of similar gauge, give this a try.

On speaker end connect:
1) positive AU to positive HF
2) negative AU to positive LF
3) positive CU to negative HF
4) negative CU to negative LF

On amp end connect:
1) positive and negative AU to positive lead(s)
2) positive and negative CU to negative lead(s)

The theory is the positive current being conduced by AU will give cleaner and more detailed highs while the negative current being conduced by the CU will give stronger and smoother bass with more coherency and cogency than merely splitting CU and AU between LF and HF during bi-wire procedures.

OK, forgo the "positive" and "negative" and lets just go with "red" and "black" for now.

OKOK lets try this again.

Silvercable on speaker end:
Connect cable's red to speaker's HF red.
Connect cable's black to speaker's LF red.

Copper on speaker end:
Connect cable's red to speaker's HF black.
Connect cable's black to speaker's LF black.

On amp end:
Connect Silver cable's black and red to amp's RED.
Connect Copper cable's black and red to amp's BLACK.

I hope this clears things up for the color and polarity challenged. = D

I see where you are confused now. Current is not supposed to be categorized as negative or positive? Then forgo that part and use the rest.

And the current going to the speaker is ac or dc?

I believe you can cancel off unwanted resonance with shelves made of any materials as long as it is well made. Each material has a different mechanical vibration signature, and you just need to compact numerous materials together that has varied density and conduction properties such as Nuance and Symposium shelves. I place paper between my metal shelves and component with some dynamat under the shelves.

Gonglee3,

I am doing almost exactly what you are doing. I've recently switched back to my ancient pair of Monster Reference 2 interconnects. And, I cut the ends off my USB cord to make a pair of CAT5 speaker cables. The results are phenomenal.
