Upgrade...Sounds great...Goes away

Sometimes a change,is just that.
When was political correctness an issue-just the facts maam.Dragnet!

where did the teleportation thing go.

Yes! Now I have something else to change/improve to move towards a sound that I am happier with. Sometimes it's change sometimes it's improvement and sometimes it's both. Adding vibration removing devise(Navcom pucks) is a change that led to an improvement in detail equaling cleaner leading edges throughout the spectrum equaling more detail. Now that there is more detail I can hear more and want to change something that I wasn't aware of before. Isn't this one example of how our systems evolve?

Samhar- YES, BUT: You're just imaging the improvement. You know: The (ubiquitous/inevitable/worthless) 'Placebo-Babble', er... I mean, 'Placebo-Effect'. KUDOS on your experimentation. Don't give up the Quest.

I know that, but I like to pretend that different tubes sound different and it makes me feel like I'm donating to a good cause when I give to the poor tube dealers. BTW I'm running Sieman El88CC's in my pre and loving them. My next fantasy CCa's, WOW this is as good as sand box therapy!!!!
