Features:
Sound characteristics: sound quality is improved in all directions, especially in the high and midrange
Tuning orientation: PG=professional audio level, purify power, enhance control, improve sound quality;
IG=instrument level, pure power supply based on PG, improve sound quality;
AG = Aerospace Grade, which strengthens emotional expression based on IG, with a gentle and noble voice.
Usage >>>
The UFEEL op amp board series are all [Plug-and-play-upgradable op amp auxiliary module]. Unplug your original op amp and plug it into the op amp upgrade board, and then plug the op amp upgrade board into the machine’s op amp socket Just go on.
Grade >>>
PG=professional audio level, IG=instrument level, AG=aerospace level.
The level can roughly correspond to PG->full play plastic seal, IG->full play pottery seal, AG->full play gold seal.
The effect can roughly correspond to: PG-> Sky-Priced Items + Sky-Priced Wires, IG-> Sky-Priced Items + Sky-Priced Wires + Sky-Priced Shelves, AG->There is no other way to achieve similar effects.
Please don’t think about what components are used on the board. Don’t use components to guess the effect. This is the result of a well-trained sound calibration experiment
UFEEL BUFFERED-OP UPGRADER use two oP work as MAIN+BUF to be one COMPOSITE-OP. Can use as a classical OP in all circuits without changing GAIN or the original functions.
The MAIN OP leads sound quality. The timbre and other acoustic characteristics are composite by MAIN & BUF. This 1+1=>2.use high performance audio OP at MAIN, use all kinds of oP even the ordinary, cheap ones at BuF may bring big surprises
Voltage-feedback OP only, BUF should be unity-gain stable, Can add a GND-WIRE on the bottom if you want
