Ben the KT120 works just fine in the Dialogue Premium Integrated as I have used them in mine with no problem. The KT150 works also. Do a search here on Audiogon as there are a few threads covering the 120 and 150. I see no reason why they wouldn't work in the amp. Also you could email Upscale Audio as they are the importer of PrimaLuna. Hope this helps.
