Any thoughts on Daitz's reconstructed pronunciation ?

[muminustrollus]

I am listening all the time to prof. Daitz's recordings of Ancient Greek and I am completely under the spell of the powerful and highly musical sound of the language as reconstructed by that American scholar.

Do you think this reconstruction is accurate? I have read very unfavorable comments on the Web (from Greeks !) who say that Sydney Allen and Stephen Daitz relied too heavily on clues provided by the Latin transcription of Greek words. They allude to ancient coins from Asia that supposedly show a different pronunciation for the upsilon.
