Agree. The Korean Rose 150 switched to ESS for Europe as did TEAC for the NT505X. Think Cary in the USA secured enough AKM4499 chips to maintain production.
Thank you bosssound for your detailed write-up. I have no experience of any other competitor so my own appraisal is subjective. Glad that it is meeting expectations even with one channel operating. My “ revelation” comment was due to its capabilities to deliver an exceptionally wide and detailed soundstage without any fatigue. Last night I listened to Keith Jarrett’s live Koln concert from 1974 on Qobuz 24/96. It was the very first CD that I bought or heard, (in Wichita,ka) when my colleague bought a Sony player back in 1983. I have enjoyed that cd hundreds of times over the years, but the TEAC reveals more ambience from the hall, creaks and a cough, plus a vibrancy to the music. I’m not capable of describing piano notes accurately, but was in no doubt that this was a more enjoyable listen than my old cd. Look forward to your thoughts when secure a fully functioning unit.
