Current price
$3,495 current U.S. authorized retail priceConfirm new rather than demo condition, standard KT88 tube set, finish, optional cage, freight and warranty at checkout because dealer stock and older reviews preserve different KT90 or KT120 tube packages. Confirm authorized new stock, exact finish, tax, shipping, return terms and checkout package before paying.
Checked 3 days agoDirect source1 evidence itemAmplifier architecture and ownership branch
dealer-supported all-tube integrated with user bias and phono
Checked 3 days agoOur synthesis3 evidence itemsExact amplifier and purchase boundary
The exact Cronus Magnum III with the invoice-defined current tube complement, remote and mains lead is retained; optional tube cage, speakers, cartridge, sources, replacement tubes, bias tool, cables and dealer setup are separate unless itemized
Checked 3 days agoOur synthesis3 evidence itemsAmplifier topology and signal path
The signal and output stages are tube based, with four user-biased output tubes and switchable Ultralinear or Triode operation. The current manufacturer page anchors the standard KT88 configuration; older KT90 or KT120 review packages must not be inherited
Checked 3 days agoOur synthesis3 evidence itemsContinuous power, impedance and load boundary
The current manufacturer page rates 100 watts per channel in Ultralinear operation and does not state a comparable Triode figure, with separate 4- and 8-ohm transformer taps. Older award summaries report 90 watts for a different tube package; use the invoice, current manual and correct speaker tap rather than blending them
Checked 3 days agoDirect source3 evidence itemsAnalogue inputs, preamp and bypass paths
Three RCA line inputs, a configurable phono input and buffered variable outputs feed the integrated path. There is no balanced input, power-amplifier bypass or fixed home-theater mode, and variable outputs are not automatic subwoofer crossovers
Checked 3 days agoOur synthesis2 evidence itemsDigital, television, Bluetooth and network path
There is no onboard DAC, optical, coaxial, USB audio, HDMI, Bluetooth, Wi-Fi, Ethernet or streaming service. Every digital or network source is an external component with its own grounding, gain, support, account and privacy boundary
Checked 3 days agoOur synthesis3 evidence itemsPhono, cartridge and headphone boundary
The internal phono stage offers separate MM and MC gain and loading choices within documented ranges. Cartridge output and recommended loading must match the chosen setting; the tube headphone output retains heat, load and hearing-exposure boundaries
Checked 3 days agoOur synthesis3 evidence itemsSpeaker terminals, subwoofer and output boundary
Separate 4- and 8-ohm output taps serve one speaker pair, while buffered variable RCA outputs can feed a compatible powered subwoofer. No internal bass management, main-speaker high-pass, delay or room correction is provided
Checked 3 days agoOur synthesis2 evidence itemsRoom correction, tone, control and bypass
There is no tone control, measurement correction, app or programmable level limit. The relevant commissioning controls are cartridge settings, output-tube bias, output mode and the exact speaker tap
Checked 3 days agoOur synthesis3 evidence itemsMains power, heat, ventilation and placement
Exposed tubes and internal high voltage create burn, shock and fire risks during and after operation. Add the optional cage around children or pets, preserve generous overhead clearance, keep combustibles away, let tubes cool and never open the chassis or bypass the fuse
Checked 3 days agoOur synthesis3 evidence itemsSoftware, service license, account and privacy
Core operation is offline and has no app, account, subscription or firmware dependency. Any external streamer, DAC or room processor retains its own license, update, privacy and support terms
Checked 3 days agoOur synthesis3 evidence itemsFirmware, warranty, parts and regional service
Rogue publishes the exact manual and current factory contact, with a retained three-year amplifier and six-month tube warranty boundary. Tube wear is consumable rather than a fixed failure schedule; log bias, channel behavior and tube identity and use competent dealer or factory service
Checked 3 days agoOur synthesis3 evidence itemsHearing, electrical, tube and installation safety
Amplifier and headphone capability are not safe listening levels. Use the exact supported mains supply and speaker load, power down before rewiring, keep ventilation clear, keep liquids away, control cable strain and exposure time and never open or service energized equipment. Tube models retain lethal voltage and burn risk after shutdown and require their exact manual and competent service.
Checked 3 days agoOur synthesis3 evidence itemsSound, compatibility, reliability and outcome boundary
No amplifier topology, wattage, impedance label, protection circuit, DAC, network service, phono stage, room correction, cable, review, owner report, warranty or service plan guarantees sound quality, speaker compatibility, safe listening level, reliability, uptime, software continuity, resale or any listening, health, safety or commercial outcome.
Checked 3 days agoOur synthesis5 evidence itemsCurrent verdict
The serviceable all-tube referenceCronus Magnum III is defended for an owner prepared to manage tube heat, bias, consumables, output taps and dealer service in exchange for a complete analogue and configurable phono path.
