Tom Evans The Vibe Feedback

I've had my Vibe for years now and have used it with many different amplifiers and sources. I find that I can make it sound all kinds of ways depending on the amp/source I use with it. It is not up-front if used with a laid-back amp. It is super clear and detailed in all cases, without throwing detail out at you like some preamps I've had. It can be subdued or it can be exciting. It is the most transparent piece of equipment I think I've ever owned.

I've got a vibe with the pulse 2 power supply..everything I've researched shows a lithium logo on the back, except mine....I figure mine is an original before the lithium upgrade....anybody got an idea of what the retail was on my vibe, and when it was most likely manufactured?

My idea is the obvious one you already thought of and for some strange treason discarded..........cheers,Bob
