Excellent 2ch preamp with ht pass thru. Barely used and in excellent condition. Incredible sounding unit for the price. I will not be building the system that I had planned so the wife says some things must go. Here is some info from audio audioadvisor where I purchased the unit.
Parasound's NewClassic Model 2100 is a versatile two-channel preamplifier that's equally expert with venerable and modern technology, from vinyl to MP3. A low-noise phono input provides the correct gain and load for both MM and MC cartridges. The Model 2100 also enables you to upgrade your present surround sound system for serious two-channel, audiophile-quality listening.
"The Parasound 2100 and 2250 [power amplifier] offer sound quality across the board so good, I would have thought you'd have to pay at least $3,000 to get it," reports Chris Groppi in his June 2008 review for Secrets of Home Theater and High Fidelity. "If you have $2K to spend on a preamp and amp, you can't go wrong with the Model 2100 and 2250."
"The NewClassics make a fine upgrade for those wanting to ditch their mass-market receivers and step in to the world of hi-fi separates," writes Clarke Robinson in his November 2007 review of the Parasound Model 2100 preamp and Model 2125 power amp for EnjoyTheMusic.com. "I am very easily excited by the music they produce. For that they get my recommendation."
Front-panel iPod / MP3 Input
The NewClassic's front-panel MP3 input makes connecting your iPod or other portable player really convenient. The Model 2100 even increases level automatically via a 12dB auto gain offset whenever you plug your portable MP3 player into the front panel jack to make sure it plays at the same volume as your other sources.
Left, Right, and Sub Bypass
Left, right, and sub bypass jacks make it simple to use the Model 2100 and your surround sound receiver in the same system, even if your system has a subwoofer and small left and right speakers. This great feature lets you keep the 2100 directly in the signal chain and play either stereo or surround sound without messing with wires. Automatic pass-through is activated as soon as you turn off the 2100. And bypass input can be selected via remote.
Built-in subwoofer control is another key feature. Parasound really thought of it all with the Model 2100. An adjustable subwoofer crossover provides analog bass management for your stereo sources, and you can adjust the subwoofer level on the front panel. Also included are separate output jacks for full range (large speakers), and 80 Hz high pass filtered (small speakers). This lets you push only frequencies about 80 Hz to your satellite speakers, without needing an expensive external crossover.
Switchable Phono Stage / Line Stage Input
The Parasound has seven inputs and a built-in phono stage. One input pair can be switched for MM or MC phono cartridge with correct input impedance. But if you're not a vinyl junkie, the input isn't wasted. Just flip the switch, and it becomes a line-level input. Needless to say, the built in phono stage sounds superb, but you would expect nothing less from the fuss-budgets at Parasound.
Custom Installation Features
The Model 2100 offers a 2-way RS-232 serial port connection for integration with Creston and other whole-house controllers. It also provides external IR repeater input and loop out jacks, as well as a remote control with discrete codes for Off and On. Two auto turn on modes (AC power, 12v trigger) add to the flexibility. And selecting automatic turn on / off defeats the front panel power button.
Other features include headphone jack with auto mute for line out jacks, a motor-driven analog volume control, a balance control, bass a treble controls with defeat button, wireless remote with tone control on / off button, and a detachable IEC AC cord. The Model 2100 uses a high-current power supply and accepts both 115v and 230v AC. Voltage is automatically selected.
