6 Moon’s Srajan Ebaen did review the 30K flagship Allnic L 10000 DHT line stage that utilizes the 300b and lacks an output transformer thus an OTL component. The Allnic 1500 integrated amplifier uses the 300b in a traditional power amplifier output stage fashion with output transformers . Although different types of audio components, I agree with David. The review provides useful information/insight concerning Allnic’s design, technical and engineering competency. They are a high quality manufacturer of audio products.
