FET input + Class A/B MOSFET out = 50 Watts into 8 Ohms, 95 Watts into 4.
Cees Ruijtenberg of Metrum and now Sonnet fame is probably best known for his DACs, like the Sonnet Morpheus that caught my fancy when I reviewed it in September of last year. The fully balanced Kratos Mono Power Amplifiers are fairly straight forward as you can see—RCA or XLR in and a single pair of speaker binding posts out on each mono block. Just add power and a front end.
A front end very much like the new, and newly arrived in Barn, Sonnet Pasithea DAC/Preamp. Yes, I’m going to review them as a stack of Sonnet. Just add speakers.
The Kratos literature suggests they share some sonic qualities with a tube/ss hybrid design, something I look forward to listening for. Stay tuned!
