Better is relative to the listener. Ultimately? probably. But if my room was bigger and my speakers (Avantgarde Duo XD) had more room to breath, I'd probably prefer the SIT1.
But for me, I'm already at the minimum distance. I actually prefer a not quite as energetic presentation and I like a mid hall listening experience.
If I had efficient conventional speakers, I think the SIT1 would offer a better experience but there's no way I'm getting rid of my Duo. Amazing you are there experience as it is now.
I also love my Job integrated amp and Job 250 monos, as well a my Valvet E2SE and Luxman MQ300 on them.
All different flavors of good.
As compared to my SIT3 amps (yes I have a backup), they are a little more ballsy, have a bigger sound-stage, are just as smooth and have a little closer presentation.
Do you mean say the SIT1 are better than the SIT3 ?
