High Performance Preamplifier
£4,025.00-
Push the Power of Audio Control
”Simply put, it’s one of the best sounding two-channel preamplifiers I’ve ever heard.” – ‘Home Theater Review – 5/5’.
STR Preamplifier includes a high-resolution preamplifier and a digital section, with support for asynchronous USB up to 32-bit/384 kHz PCM and DSD 2.8/5.6 MHz sources. This high-quality USB audio input transforms digitally stored audio from your Windows or Mac computer into warm, natural analog sound.
Reference stereo sound from the AV pros
The Canadian company that’s world renowned for making some of the best AV equipment in the world, also produces stereo amps and, as you’d expect, they’re something special. The STR Preamplifier combines a high-resolution analogue pre-amp with built-in DAC (Digital to Analogue Convertor) for reference sound quality. Thanks to Anthem’s acclaimed ARC room correction system, perfect results are guaranteed in all spaces.High-resolution sound
Handmade circuits, featuring top quality components ensure a clear, dynamic sound. For the best possible sound with your analogue sources, Analogue Direct bypasses auxiliary circuits for the ultimate in detail.Anthem Room Correction for professional results in any room
Designed in conjunction with the National Research Council of Canada, ARC (Anthem Room Correction) provides a sonic output that’s ideal for your particular room. Using the supplied mic and stand, 5-10 placement measurements are made. Next, use the supplied software on your PC to determine the optimal settings on the amp to suit your room. The result is a sound closer to the original – in any room. (Professional set-up recommended).Connect your digital sources
Featuring a built-in 32-bit DAC, the STR Preamplifier connects directly with your digital sources. With no fewer than two optical and two coaxial inputs, there are enough inputs for a CD, TV, streamer and set-top TV box. For the best sound from your home computer or laptop, there’s also an Asynchronous USB input – ideal for steaming hi-res music files right up to 384kHz/32-bit and DSD 5.6 MHz.Up-sampling to 192kHz-32-bit
Even if you don’t have access to Hi-res music files, you can get much of the benefit from your existing digital sources. Thanks to digital up-sampling, all digital inputs can be upsampled to 192 kHz/32-bit resolution for enhanced clarity and detail.MM and MC phono inputs to suit most turntables
Making the STR Pre-amp suitable for all types of turntable, the built-in phonostage accepts both MM (Moving Magnet) and MC (Moving Coil) cartridges. The phonostage also offers six pre-RIAA curves plus adjustable settings to get the best sound from your cartridge and records.Bass management for two subwoofers
The STR Preamplifier gives you far more subwoofer options than most stereo pre-amps. Twin outputs let you use one or two subs. If you decide on two, they can be configured for left and right or dual-mono – whatever you feel sounds best. Used in conjunction with Anthem’s ARC, bass management gives seamless blending for smooth, ‘thump-free’ sound.Professional XLR, balanced interface
More usually found in studios, XLR balanced sockets offer excellent noise resistance and a ‘locked in’ connection for the lowest distortion and most secure connection. The STR Pre-amplifier offers a class-leading four inputs, four outputs for the analogue stage and a further digital XLR input.Make the most of all your digital and analogue sources, with the Anthem STR Preamplifier at the heart of your system.
Moving Coil and Moving Magnet Phono
Anthem has also taken into consideration the resurgent popularity of vinyl records, and has included separate inputs for moving magnet and moving coil cartridges, with the phono section completely shielded to maintain a clean signal. The transparency and refinement of the STR Preamplifier reveals the hidden magic of classic media.
In addition, the phono curve is continuously adjustable for proper playback of any record that predates the RIAA equalization standard.STR Features & Functions
