Ampli barato bravo vs ne5532
« en: Noviembre 08, 2016, 23:03:42 »
He mirado opciones baratas para mover unos hd580, y he llegado a estos 2 amplis, por un lado las valvulas que dicen le van muy bien a los sehneiser, pero que me dan aspecto de producto tipo kit o brico.
Luego he visto unos linep a929 con chip ne5532 que tienen buena pinta:

Two-channel switch circuit(3.5 headphone base and gilt RCA base) replaces input signal with no need to unplug, just turn the panel option switch.
High-precision power bleeder circuit ensures the stability of circuit and reduces DC shift of output.
Advanced input and output connecting base ensures the smooth and durability of signal channel.
NE5532, well-tailored for the high-performance audio system in best signal amplification, acts as front-end amplification.
High-sensitivity headphone protection circuit has your headphone protected.
6.35mm headphone output socket, optionally added with 6.35-3.5 switching base, applicable to HI-FI headphone and high-power impedance headphone.
Original potentiometer made in Taiwan, with small sound loss, high balance, good hand feel and durability.
Aluminum alloy housing has a high density of wiredrawing in oxidation treatment, good-looking and noble with screen, but with no color-shading as paint spraying.
