If you're looking for the best deal on an integrated amplifier which also provides the resolution and clarity as those costing many times over, look no further.  An extremely wide sound stage and imaging that takes you to the music are just a few attributes of our latest creation.  Many of the features derived from the STP preamp have given this unit an edge that many others are looking for.

It all starts with our proprietary fully balanced dual FET unity gain buffers on the front end to welcome incoming signals.  Our true resistive-ladder volume control is fed from the FET input stage and offers exceptional tracking.  Our line stage that couples the amplifier to the front-end offers a balanced output regardless of the selected input.  This offers much better common-mode rejection, and a quieter background.   

Some features the STI series have that others don't is the same HT bypass feature as the STP, and a loop through feature.  Like the STP, you can connect a DC trigger cable to your Pre/Pro (and set-up the proper input in the setup menu) to automatically configure the unit for HT use.  When an input is selected to be used as the HT input, the DC trigger can be activated by your Pre/Pro to “power up” the unit, and automatically set the volume to unity gain.  This allows for all volume controls to be made through the surround processor.

If you're looking for the ultimate in transparency, and an unbelievably accurate pre-amp, then we have the product for you. Spot on imaging and an extremely wide sound stage are just a few attributes of our STP preamp. We had so much fun with the proto-type it's actually intrigued us to continue making changes to the design than intended.  More improvements were also made beyond the standard STP, the STP-SE was born.  In the Special Edition unit we are upgrading the internal input/output wiring to Kimber Tcss (multi-gauge, multi-strand, continuous strand pure copper).  We are also upgrading 4 crucial power-supply capacitors to our W4S Low ESR "Super Cap".  These improvements offer improved 3-D imaging and instrument placement. iltering caps (4-22,000uf caps) are upgraded to the Wyred 4 Sound Low ESR "Super Cap". These improvements offer improved 3-D imaging and instrument placement. Specifications

The ST series stereo amplifiers offer a huge range of flexibility. With balanced outputs ranging from 125-570 watts in 8 ohms, and 195-1140 watts in 4 ohms per channel! Each channel of the amplifier has independent inputs for a balanced or unbalanced connection which are easily selected by the selector switch on the rear of the unit. The stereo is basically 2 mono amplifiers in one chassis, a true dual mono.  The only common connection between the channels besides the chassis is the AC power. Our proprietary input stage was designed for optimal performance, and transparency. The dual, balanced FET input stage offers excellent integration with any source, with maximum openness. Connection of these amps to a tube type source is a match made in heaven! Specifications

The SX series amplifiers offer a huge range of flexibility. With balanced outputs ranging from 125-570 watts in 8 ohms, and 220-1225 watts in 4 ohms! Each amplifier has independent inputs for a balanced or unbalanced connection which are easily selected by the selector switch on the rear of the unit. Our proprietary input stage was designed for optimal performance, and transparency. The mono amplifier offers the ideal in channel to channel isolation, and the ultimate in sonics. The dual, balanced FET input stage offers excellent integration with any source, with maximum openness. Connection of these amps to a tube type source is a match made in heaven!  

Wyred 4 Sound's ultimate expression of the Bang & Olufsen ICE modules is found in the SX range of monoblocs: starting with the sweet and detailed SX-250.

Twice the power of the SX-250, with essentially the same fluid, gutsy character, the SX500 is the best selling Wyred 4 Sound monobloc, with the lowest distortion.

The Absolute Sound's 'Editor's Choice' two years running, the massively powerful SX1000 is one of the best bargains in audio today: high end, but not high priced.
