Should I Upgrade My Krells

Here are the details. I have a Krell 150A Amplifier, Krell 250P Pre-Amplifier, Cary 303/200 CD Player, Vienna Acoustic Bachs, AudioQuest Viper XLRs throughout. Some Very Thick Monster Cable speaker wire (M100 series I think). I bought the Krells off of E-Bay in ABSOLUTE pristine condition 1 1/2 years ago. I will say that my Bachs are HERE TO STAY as I'm a silk dome tweeter fan as well as a Vienna fan! IMHO, nothing sounds better than Vienna. . . again MY personal opinion. Also, the Cary is quite phenominal!!!

When I purchased the Krells on E-Bay, I paid $2,150.00. When new, both units went for $4,800.00.

It has been said that sometimes Krell can be a bit too agressive and that may be true (I don't know with authority). If this is in fact the case, I believe that since the Bachs and Cary are very much laid back, this offsets the brashness of the Krells. I think the Krells do well in producing bass on my Bachs especially since they have no bass driver, but rather are ported on the back. IMHO, I feel as thought the midrage is positively intoxication and the high end can be likened to mercury. If I had one complaint, it would be imaging. I wished that my system was able to do this more effectively!!!

I went to audition the Mozarts side by side to the Bachs at my local Tweeter store. To my amazement, I truly believe the Bachs sounded better! Further, the set up I heard at the store which included B&K electronics and a no name cd player sounded better than my home system???? In short, I experienced far better imaging than my home system???? Can B&K be on the same level as Krell in this aspect?? I know my Cary is not in question as it's about as good as it gets at the price point I paid.

This all being said, should I replace the Krells? I don't want to sacrifice what I already have in Bass, Midrange, and Treble. I want to improve the imaging as I know that can be done and have heard it demonstrated!!

Any advice would be welcomed!
