The NuPrime IDA-8 consists of an ultra-low-noise integrated amplifier and digital-to-analog converter that decodes USB PCM 384 and... DSD 256 with the convenience of wireless audio in a small, handsomely designed home stereo component. NuPrime's new Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology in a milieu of un-measurable noise. The IDA-8's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to be believed. With all stages in one chassis, the IDA-8 avails itself of the shortest possible signal paths in order to facilitate vanishingly low levels of noise and distortion for a black-velvet background to music. The listener's initial reaction might very well be "I can't believe my ears!" The IDA-8's low noise floor is further complimented by an innovative volume control based on a thin-film resistor design that positions a single resistor in the signal path for each volume setting. Volume changes occur in 99 precise 0.5dB increments for each input's individually adjustable volume level. Precise level matching is a breeze, as is the user's ability to make comparisons of music sources.

Phono Preamps

Our flagship model combines exceptional phono preamp performance with three additional aux level audio inputs, then adds an variab...le output level control. Soft-touch switches control power on/off and source selection. While off, the TC-754 even remembers what source was last selected and reselects it when powered back up. The output level control allows connection to a power amp either directly or through an equalizer; or it can simply be used to fine tune the audio level sent to your computer sound card or receiver. Spectacular RIAA equalization accuracy and a S/N ratio of 85dB make the TC-754 our best performing phono preamp; its additional features are extra icing on the cake!

The dbx 286s is a full featured Channel Strip Processor that delivers a studio quality microphone/instrument preamplifier and four... processors that can be used independently or in any combination. Why mic up vocals and instruments through a noisy, blurry mixer? The sonically pristine dbx 286s Mic Preamp has all the features you need, including wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter to remove low frequency hum, rumble or wind. Use the patented dbx OverEasy compressor to transparently smooth out uneven acoustic tracks or deliver that classic "in your face" vocal performance that only a dbx compressor can. Eliminate vocal sibilance and high frequency distortion from instruments such as cymbals with the frequency tunable De-Esser. Fine-tune the Enhancer HF Detail control to add sparkle and crispness to your tracks and make adjustments to the LF Detail control to add fullness and depth to vocals and bass instruments while cleaning up the muddy low midrange frequencies. And, the separate threshold and ratio controls on the Expander/Gate allow you to subtly reduce headphone leakage or radically gate noisy guitar amps. The dbx 286s offers a full compliment of metering and status LEDs to visually guide you to achieving the right sound. The floating balanced XLR Mic Input accepts balanced or unbalanced inputs to easily connect to professional and home studio microphones. The additional 1/4" TRS Line Input can accept balanced/unbalanced signals to process live electronic instruments or pre-recorded tracks at mix down. Use the Insert jack to interface between the Mic Preamp and the signal processing sections to "loop out" to external processors (such as EQ or delay unit) or to mix the Mic Preamp's signal out to an external destination. read more
