Preamplifiers - Hifiverse audio equipment catalog

The Classic PRE preamp has the same functionality as the pre-section of the integrated amplifier. The power supply unit is equipped with a 74 VA transformer. In total, the circuit is powered by 11 separate voltage regulators. There is also a port for an external PSX-R power supply. Dimensions 215 x 75 x 365 mm, weight 4.4 kg.

The model is equipped with a DAC unit on an ESS ES9038Q2M chip with support for high–resolution audio decoding – PCM streams are received with parameters up to 32 bits / 768 kHz, and DSD - up to DSD512.

Tube-based line-stage (6 x 6H30P dual triodes, plus 6550WE and 6H30P in power supply) offers standard 2V RMS into 200K ohm balanced load with maximum balanced output capability is 70V RMS.

The “Hybrid Passive Attenuator” preamplifier ensures high-quality impedance matching of the connected components. With an input impedance of 47 kOhm, the output is 250 Ohm. The basis of the audio path is a balanced transformer with a pair of separate windings - it provides a 3-step gain switching (-10, 0, +6 dB).

The Revelation 2 Preamplifier based on Line Stage Gain Module with servo circuit monitors the signal and corrects for inconsistencies. Switched-Mode Power Supply (C-SMPS) offers more than 20 dB quieter DC voltage.

Based on a matched pair of Western Electric WE300B triodes, uses fully balanced input and output stages and operating in pure Class A this preamplifier offers very high sound quality.

The Onkyo Icon P-80 network preamplifier is equipped with a built-in phono preamplifier that supports MM and MC cartridges, an HDMI ARC input and wireless connectivity options such as Wi-Fi, AirPlay 2, Chromecast and Bluetooth. The new preamplifier supports popular streaming services, including Spotify, TIDAL and Amazon Music, and is Roon Ready certified. The built-in DAC operates on the powerful Asahi Kasei AK4452 chip with support for PCM up to 32 bit / 768 kHz.

The Nagra Reference Preamp has become the flagship of the Nagra Audio preamplifier line and, according to the manufacturer, will be the perfect partner for the new Reference Amp monoblocks. The Reference series components, which include the Reference Turntable, the Reference DAC, the Reference Preamp and the Reference Amp mono power amplifier. The Reference Preamp sets a new standard for analog preamplification.

Fully discrete, balanced Dual Monaural line-stage (preamplifier) with heavily regulated and filtered power supplies and extreme wide-bandwidth frequency responses.

The Audiolab 9000Q preamplifier is equipped with a DAC unit based on the ES9038PRO chip from ESS Technology. The DAC module is capable of decoding PCM audio up to 32-bit/768 kHz and DSD up to 22.5 MHz (DSD512), as well as MQA. There is also Bluetooth version 5.0 with support for aptX HD and LDAC codecs. Analog connectivity includes three unbalanced line inputs on RCA connectors and one balanced XLR, as well as a phono input for working with moving magnet (MM) cartridges, which has been further improved compared to that installed in the 9000A integrated amplifier.

The amplification stages in the Riviera Audio Labs APL1 operate in pure class A. Riviera Audio Labs APL1 uses a more powerful power transformer and a capacitor block of the power supply filter. The preamplifier also uses an input transformer circuit for both types of inputs.

The manufacturer states that this model was developed as a linear preamplifier that combines the rich and mature sound of the G-70 with the power of the flagship G-1000.

The TEAC HA-507 model is made as a fully balanced scheme with a “dual mono” configuration and is capable of providing an output power of up to 6.7 Wt per channel when driving headphones with a nominal impedance of 32 ohms with a balanced connection, which makes it suitable for working with a wide range of headphones.

QUAD has announced the revival of its legendary QUAD 33 preamplifier.

hARt Lab Tune Two is a new High End preamplifier with on-board digital-to analog converter, streamer, phonostage and headphones output.

Marantz LINK 10n is a reference-class preamplifier with a built-in network audio player, developed using advanced Marantz technologies that made MODEL 10 and SACD 10
