Its symmetrical dual-mono design places two fully independent, mirror-symmetrical Class-A amplifiers under one bonnet, each with its own power source, delivering up to 10W per channel from the balanced XLR output. Six Burson discrete opamps, dual MUSES72320 volume controls and Burson's Silent Power modules complete a compact, fully balanced design available in Standard and Max editions.\u003c\/p\u003e\n\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\n\u003cp\u003eThe Soloist GT4 brings much of the character of Burson's flagship amplifiers to a more compact chassis - powerful, dynamic and remarkably composed, with deep, well-controlled bass and a wide, three-dimensional soundstage. Because it is a dedicated analogue amplifier, it pairs beautifully with the DAC or streamer of your choice, and the dual-mono layout keeps imaging precise and channel separation exceptionally clean. Three levels of hardware crossfeed, three gain settings and stereo balance adjustment let you fine-tune the presentation to your headphones and music. As a preamplifier with a dedicated subwoofer output, it is equally at home driving a pair of powered speakers or a power amplifier on your desktop.\u003c\/p\u003e\n\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10W Pure Class-A Dual-Mono Design:\u003c\/strong\u003e Two fully independent, mirror-symmetrical Class-A amplifiers, each with its own power source, deliver up to 10W per channel into 32 ohms from the XLR output while eliminating crosstalk and interference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual MUSES72320 Volume Control:\u003c\/strong\u003e Two MUSES72320 precision volume chips with discrete buffers - one per channel - offer a -112 dB dynamic range with accurate channel matching and pristine stereo separation at every listening level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiscrete Opamps \u0026amp; Silent Power:\u003c\/strong\u003e Six swappable Burson Vivid discrete opamps and Burson's Silent Power modules, with noise filtering over 200 times better than standard regulators, ensure a clean, vanishingly low noise floor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Support:\u003c\/strong\u003e Hi-Fi Centre is an Authorized Dealer for Burson Audio, ensuring authentic products backed by full manufacturer warranty coverage, in-store demonstration and expert technical support.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand \u0026amp; Model:\u003c\/strong\u003e Burson Audio Soloist GT4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Class-A Headphone Amplifier \/ Preamplifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEditions:\u003c\/strong\u003e Standard, Max\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Topology:\u003c\/strong\u003e Pure Class-A, fully balanced, symmetrical dual mono\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Power (XLR \/ Single-Ended):\u003c\/strong\u003e 10W \/ 5W at 32 ohms; 8W \/ 4W at 100 ohms; 3.8W \/ 1.9W at 150 ohms; 1.3W \/ 0.65W at 300 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 3 levels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrossfeed:\u003c\/strong\u003e 3-level hardware crossfeed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume Control:\u003c\/strong\u003e Dual MUSES72320 with discrete buffers, -112 dB dynamic range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpamps:\u003c\/strong\u003e 6x Burson Vivid discrete (V6 Vivid in Standard; V7 Vivid in Max)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Regulation:\u003c\/strong\u003e Burson Silent Power 01 (Standard); Silent Power 02 (Max)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone Output Impedance:\u003c\/strong\u003e 0.5 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre Out Impedance:\u003c\/strong\u003e 25 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 38 kohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 0 Hz - 48 kHz (±1 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD:\u003c\/strong\u003e \u0026lt;0.0015%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 2x XLR, 2x RCA, 1x mic bypass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1x XLR preamp, 1x RCA preamp, 1x RCA subwoofer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone Outputs:\u003c\/strong\u003e 4-pin XLR, 6.35 mm single-ended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Modes:\u003c\/strong\u003e Headphone, Headphone + Subwoofer, Preamp + Subwoofer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Features:\u003c\/strong\u003e Stereo balance control, remote control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e External - 24V 5A PSU (Standard), Super Charger 5A (Deluxe), Fusion Core (Max)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x D x H):\u003c\/strong\u003e 255 mm x 270 mm x 70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approximately 5 kg (main unit)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the differences between the Standard and Max editions?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll three editions share the same Soloist GT4 chassis, 10W dual-mono Class-A amplifier and connectivity - the differences are in the opamps, voltage regulation modules and external power supply. The Standard edition uses Burson V6 Vivid opamps, Silent Power 01 modules and a 24V 5A power supply. The Max edition includes everything in the Deluxe edition and adds Burson's GaN-based Fusion Core power supply for the greatest dynamic headroom.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the Soloist GT4 include a DAC?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The Soloist GT4 is a dedicated analogue headphone amplifier and preamplifier, so it needs an external DAC or streamer connected to its XLR or RCA inputs. This lets you choose your preferred source and upgrade it independently. If you would prefer an all-in-one solution with a built-in DAC, consider the Burson Conductor GT4.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the Soloist GT4 compare with the Soloist Voyager?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth are 10W dual-mono Class-A headphone amplifiers and preamplifiers with dual MUSES72320 volume controls, six discrete opamps, three-level crossfeed and a subwoofer output. The Soloist GT4 is housed in a more compact, lighter chassis, while the flagship Soloist Voyager uses a larger Cool Case chassis and includes Silent Power 02 modules in every edition. Our team is happy to demonstrate both side by side in our showroom.\u003c\/p\u003e","brand":"Burson Audio","offers":[{"title":"Standard","offer_id":67824790110261,"sku":"Timekeeper GT4-Standard","price":5600.0,"currency_code":"CAD","in_stock":true},{"title":"Max","offer_id":67824790143029,"sku":"Timekeeper GT4-Max","price":7000.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/BursonAudioTimekeeperGT4.jpg?v=1793118576","url":"https:\/\/hificentre.com\/products\/burson-audio-timekeeper-gt4-mono-power-amplifier-pair","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
