Cheap tweaks...What would YOU reccomend?

This may sound weird, but if you wear your hair long, pulling it back away from the ears will actually improve the sound! (Thick hair is a VERY effective sonic damper!)

Hi, Haoleb. Tweaks are tricky. They all do something to the sound in your room. Listen to the effect after doing each one and decide which way it sounds best "to you". One of the cheapest tweaks I know is lifting all cables, cords, wires and power supplies off the floor. Mine lay on thick pieces of stryfoam. I actually have the preamp sitting on a 2"inch stryfoam because it works in my system. Now the turntable likes to be on three marbles riding in spoons glued to vibrapods which sit on stryofoam on a granite tile. Sounds silly but the end result is analogue glory, [to my ears and others who have heard the system]...I use large marbles riding in small bottletops on three granite tiles under the speakers. Why? Well the bass articulation and speed are greatly enhanced. But this may not work for you. Remember, the spirit of tweaking is fun and learning about your system....take your time with the tweaks and you will be, [like with the inner tubes], surprised. I've tried the tubes and yes, they work...cheers, bluenose

I like the homemade room lenses and rollerblocks a lot.
My best tweek in antistatic spray on my whole system. Interconnects, speaker cables, power cables, plc, ics inside the components, wires inside the components etc. The improvements include a bigger soundstage, crisper dynamics, and reduced glare/brightness.

You could get a copy of Robert Harley's book, "The Complete Guide To High-End Audio". Lots of good information in there.

If you haven't replaced your receptacles at the wall (or in your line conditioner if you have one), I'd strongly recommend the Arrow Hart 8200 (available for about $8 U.S.) If you have two or 3 receptacles that your system is drawing from, this will make a very worthwhile improvement to sound quality. I also like the vibrapods (bear in mind that I have a relatively modest system and we are talking about "cheap" tweaks) and use them under both electronics and speakers (floorstanders). If you have a budget CD player, you might want to experiment with damping the interior of the casing (commercial industrial floor tile attached with double sided heavy duty carpet tape works well); I've had good results doing this. All of these are sub $20-$25 tweaks ( a little more if you start piling on the vibrapods), which I figure is pretty cheap.
