The spiral wire tail on this piggy is made of a secret alloy of copper, titanium, magnesium, and unobtainium. When placed atop the amplifier, the wire tail acts at the quantum level, imparting a sense of organic ease and coherence to the recording.
The sleeping piggie tweak imparts a relaxed sound to the system. It's especially useful with baroque chamber music performed with squeekie-weekie sounding period instruments that otherwise might sound harsh and strident.
Solid state amps can sometimes sound harsh and bright, but the crystal piggie tweak restores the crystal clarity of an original master tape. Selling for $100, this Waterford crystal piggie is the 2nd most expensive tweak on this page, and is therefore the 2nd most effective.
The megapig tweak creates the subjective impression of adding an extra octave of bass extension. With the megapig sitting on top, the eight 7" Vifa XT woofers in this line array load the room with bass to the point where you can feel it in your chest! The total impact can be varied by piggie placement - over the woofers for greater bass impact, the middle for less.
The pink piggie tweak rounds out the midbass nicely. Piano recordings especially become richer and fuller sounding. I named this piggie Jezebel because of her shameful behavior around boy piggie tweaks, so be careful to isolate her or you will have more little tweakies than you need.
You can bank on this one improving the sound of your system.
I live in Texas, and one requirement of any Texas system is that it must sound Texan, which is the opposite of wimpy. My Grant Fidelity tube processor helps by itself, but when I stacked the UT piggie atop the transformer housing I heard an enhanced midbass that reminds me of a fat Texas girl I once saw doing the two-step at a C&W dance hall.
The audio world is fueled by bullshit, but this simple elixir is the most effective tweak of all I have heard. Only $500/bottle.
