KRELL Solo 575 XD Newest Version
This Krell Audio’s biggest baddest Monoblock Power Amplifier with 575 Watt continuous output and Featuring Krell iBias Technology Circuitry Highlight (KRELL Solo 575 XD).
Krell iBias Class A technology allows our latest amplifiers to run in full Class A mode to full power while minimizing
heat generation. All signal gain is realized in the current domain using discrete, proprietary, multiple-output current mirrors with extraordinary open loop linearity. There are no generic integrated circuits or op amps used anywhere.
Current mirrors in the final gain stages use a new output power device that operates at a 73% higher voltage,
delivers almost 10% more current, and offers 120 watts of additional power handling capability as compared to previous devices of all the amazing amps we get to audition this one fits neatly in the middle of the cost factor being expensive bit not offensively like a mortgage on your home expensive and considering.
This amp built for those that own or are buying top 5% of the worlds best of the best Not pricey in comparison to others in its performance class. Quite honestly after listening to the NEW UPGRADED XD version I immediately thought of amps costing 3x’s the Krell’s reasonable price tag and had to grin knowing KRELL was back from the nearly dead to the top of the world with this amplifier!
The signal path is fully complementary and balanced .Independent complementary pre driver and driver stages for the positive and negative output transistors make the output stages extremely fast and linear.
Krell amplifiers are fully direct-coupled, with no capacitors in the audio signal path. This design gives the Krell amplifiers lower internal impedance, which allows firmer, more precise control of your speakers.
Krell CAST Circuitry
Krell CAST Circuitry delivers the purest signal when connected to Krell CAST equipped preamplifiers.
Power Supply Highlights Four 750VA toroidal transformers feed amplifier modules that include the audio circuitry, rectifier, and power supply filtering mounted to an individual heat sink.
This design shortens the electrical path from the power supply to the output transistors, reducing the overall impedance and allowing the circuit to respond faster and control the speakers better and more accurately.
Feature Highlights Network connectivity brings convenience, monitoring, and reporting to end users from any smartphone, tablet, or laptop. Amplifier configuration options include display brightness and timeout. For energy conservation, the amplifiers can be programmed to power off at a preset time of inactivity.
Individual channels can be muted and firmware updates can be initiated from the web server.
Excessive current, output DC, fan speeds, short circuit, and overheating are all monitored in real time. Messages are displayed on the front panel and reported on the web server interface. Additionally. end users can be sent an email notifying them of any operational anomalies.
