I'm pretty set on keeping my Silversmith Fidelium cables. Of all the cables I've tried over the years (and they're quite a few and almost all more expensive than the Silversmith's), these the most neutral, detailed, yet smooth cables I've tried.
Same goes for the digital front end. Replacing the PS Audio DirectStream Sr (with multiple modifications) would cost way more than replacing the amp.
Also, I'm not going back to separates again. I've had some many over the years and the simplicity of an integrated is getting more appealing the older I get.
So I'm either going to stay with the INT-25 (and there's a lot that I love about it!) or I'm going to a tube integrated (and there's a lot I love about tubes).
I do appreciate all the input and options offered up.
