McIntosh MA352 replacement

@kvpower 

The best advice you received here is to get a sub, better yet, get two! You have dismissed that. The LS 50s are stellar, but a sub(s) will knock them out of the park far more than better tubes. Subs are not just for bass output. 

@jeffreyw I tried. I guess their mind is already made up even before this post.

@kvpower IMHO I would do a Gold Lion tube roll first. It's a couple of hundred $$s. If that works it will save you big bucks and you get to hang on to the Mac. If it doesn't you can resell the tubes. My bet is you will hear a significant improvement. Good luck to you.

Without maximizing speaker placement and room treatment, swapping the amp will achieve minimal (or worse) performance improvement. The multiple suggestions for stereo subwoofers is also spot on. It’s about way more than just low end. 

I appreciate all your input. I ordered 2 KC62 subs already. I’m also ordering the tubes, I'm curious to see what they will do. Thank you all.
