THX Ultra2-Certified Parasound NewClassic 2125 v.2 Plays with Clarity, Punch, and Detail: 150Wpc Power Amplifier Features Fully Discrete Circuitry and Cool-Running Operation
High-value, high-performance power amplifiers don't come much more vetted than the Parasound NewClassic 2125 v.2. The THX Ultra2-certified overachiever outputs a whistle-clean 150Wpc into eight ohms and a beefy 400Wpc in bridged mode. Delivering 35 amps of peak current per channel, NewClassic 2250 v.2 provides two-ohm stable operation with a load selector switch and drives speakers with confidence, authority, and ease. In addition to its compact 4.25 x 17.25 x 16-inch (HWD) chassis, it comes loaded with the audiophile technology and engineering for which Parasound remains famous.
Equipped with fully discrete circuitry and a high-current toroidal transformer, the 27-pound unit plays very efficiently and runs supremely cool. DC servo and relay protection circuits, a switchable high-pass filter, rear-mounted left and right gain controls, and a suite of standby, status, and high-temp indicators give you convenient options and peace of mind. The rack-mountable NewClassic 2125 v.2 also allows for auto turn-on/off via DC trigger or audio signal (with two sensitivity settings). A rear-mounted lockout switch disables the front A/B buttons for custom-install use, while heavy-duty, gold-plated five-way speaker terminals ensure compatibility with practically any speaker connections.
True to Parasound tradition, the quiet-operating NewClassic 2125 v.2 reproduces music with enticing clarity, vivid textures, expressive detail, and take-notice dynamics. Few power amplifiers with its capability, build quality, and reliability reside at its end of the price spectrum. Parasound's two-year warranty and our 100% Music Direct Satisfaction Guarantee see to it you have every reason to audition NewClassic 2125 v.2 in your home today.
