@carlsbad2 Hi, no it’s Class A, NOT Class B. Maybe 95F rather than frying an egg on my output transformer of my Class A tube EAR 890s.
The Rei amplifier distinguishes itself through the implementation of WestminsterLab’s proprietary iBias and CCS systems, which have significant electronic implications. With these technologies, the Rei achieves a notably faster warm-up time compared to typical Class A amplifiers. The iBias technology dynamically adjusts the bias, taking into account the current and load of the amplifier.
This innovative approach enables the Rei to deliver the coveted benefits of Class A amplification without the typical drawbacks. Its ability to maintain optimal performance while mitigating issues associated with heat generation and power consumption makes the Rei truly exceptional. From the site Rei | WestminsterLab
I’ve heard these amps with my speakers and my EAR 912 pre-amp/VAC Reference pre-amp. Audiophiles are selling their SET to heavy duty Boulder/Gryphon amps for these amps. They run cool, lightweight, energy efficient for Class A and sound powerful. Superior sound and power but not as inexpensive as Class D amps.
One reviewer- Intelligent handling of the bias current results in an idle power consumption as low as 60 to 80 watts, and the heat sinks, which have been given their precise shape by finite element analysis, only get hand-warm even during listening sessions.
I intend to purchase a pair in the future but I just ordered the Lampizator Poseidon Pre-amp/DAC. I am in no way affiliated with any brand other than being best friend of GroverHuffman cables as a beta tester.
