UnitiQute is Naim's new, compact digital streaming all-in-one high-end audio player. Shouldn't the above have the the following commas? UnitiQute is Naim's new, compact, digital, streaming, all-in-one, high-end, audio player. I was recently told that commas joining adjectives are not essential if there is no ambiguity without them. Is this why they have been left out? If so, why did the writer choose to use the one comma after 'new,' do you think? Thanks.
