Lively, fast & open sounding integrated under 3k?
The Triangle signature Theta’s can go down to 4ohms, and to me sounded like they needed to be livened up
A used John Curl designed Parasound Halo Hint integrated, you should be able to pickup for $3k or less, it’ll drive almost anything even has a ESS Sabre dac in it as well as a phono stage if you need it.
