This is wonderful sounding amplifier with phono stage. Please google reviews for the Obelisk, this is the Si 3 version (latest) which is said to match the performance of the previous version with the external power supply upgrade. A very healthy 50w in 8ohms. It’s been described as “Naim with Tubes” but I’d say it’s more like Naim with a deep soundstage and less emphasis on a driving bass line. It’s a great match for many, many speakers. Slightly warm but great detail. Please check out my feedback for peace of mind. Low ballers will be politely ignored.
