Hello Tube Amplification--Goodbye Subwoofer

Agreed.  Keep the sub

You all are probably right. It could enhance presence of the bottom end. I think I was just so bowled over by the new sound.  I'll check back in. 

jbhiller,

Another vote for keeping your sub. Every time I make a positive change in my system, I always have to re-examine my sub settings. Never fails to amaze! Good luck!

I'm using a pair Martin/Logan Depth i's in an acoustically treated room. I'm constantly amazed out how accurate the ML manual is.

Upgrades can often have your system sounding "perfect", soon after you may realize there is more to be had. Or the upgrade actually wasnt as cracked up to be as you thought initially.

Its almost as though your hearing is manipulated or tricked somehow by the new sound and you later realize you were taking more of a sideways step or even a step back in some cases.

I have heard others touch on similar thoughts. Is there a term for this, or an good explanation as to why it happens?

I find it can take several hours of listening to become "in tune" with the system again. Thats what I meant by let the changes "digest" a little while before making any rash decisions :).
