The T2 as a dac streamer is better than what you would get from a Star being used as just a streamer.
Even vs the more expensive Naim NDX 2 the T2 is hard to beat.
The dual ESS Sabre dac's have a more dense image focus and the soundstage is bigger.
The Naim Uniti Star is an excellent all in one, and most people use it as an all in one.
Your best bet is to sell the Star and get a T2.
