i have the xa25 which is the power amp section of the int25, i run a dac with volume control into it, so it is functionally working very similarly to the int cousin fed with a fixed output source
sonically, in build quality, and in terms of the company and people who stand behind it, it is absolutely superb, without qualification
whether it will please you more than luxman or sugden class a amps driving your speakers, i really can’t say
