Does your system sound "less full" when using it for two channel listening, multi-channel listening or both? Are you using subwoofer/s for your two channel listening? The reason I ask is that while also searching for that magic pill, I went through a similar period where I had trouble finding that sweet spot in my system's sound. The one addition that made the most significate and immediate improvement in my system sounding full and warmer was a REL sub-bass subwoofer for two-channel listening. It turned out to also be the most economical improvement to my system's overall sound quality. An easier tweak would be trying slightly different main speaker orientations. Try toeing your Revels out a little more. The result might be more subtle but it doesn't cost anything but a little time.

Of all the possibilities, this may be one of the most salient. These are, apparently, the original Studios (which I used to own) and the newer ones are significantly superior in almost every way. Consider a change here, if you insist "I am not about to return my new speaker cables....."

First off, really sorry to hear about your result. It is really frustrating to have a good result undercut with a bad one. Good old systems, change one thing and you get a cascade of changes. I can easily see myself telling someone, “yeah, I bought a new speaker cable, and it cost me $100K.”

I will say from a high level, the change you heard was what happens with greater transparency. I find an amplifier about ten years newer is typically a “wow” that sounds better and typically by being more natural with more lower midrange and bass. About fifteen years ago I replaced my 20 year old Threahold T2 and it sounded tinny and gutless in comparison with the Pass amp I replaced it with. I guess this points to a likely problem, replacement of any old piece of equipment is likely to result in a significant improvement in performance of that piece resulting in exposing a weakness elsewhere. I will say I agree with Kevin, ‘wack a mole’ is a very really likely outcome.

On the other hand, tremendous opportunity for a component upgrade cycle.

If you really liked the Krell, a newer Krell might be a good choice. I am partial to Pass designed solid state amps. But in my mind tube amps recently became a possibility with Audio Research adding microprocessor control for auto biasing and extending tube life.

After decades of reading reviews I can pretty much make a component decision without going to a dealer. But maybe read lots of reviews form your opinion. Then call up a dealer and have him set up a demo with defined equipment so you can hear 2 or 3 choices. When I fly across the country I’ll call a dealer a week before and explain my preferences and what I might want to hear. Then I show up at the appointed time.

I am not about to return my new speaker cables, so I am asking my fellow audiophiles about the likelihood of being able to "have my cake and eat it, too" by now updating my power amplifiers.

At present, I use two 20-year old Krell amplifiers (the FPB 200C for left/right; FPB 250MC for center channel) to drive my Revel Ultima Studio and Voice loudspeakers. I recognize that Krell, among others, have made significant technical improvements in their amplifier designs and performance. Would Krell's new XD amplifiers provide a "richer" sound than my current models? Are there other manufacturer's amplifiers I should consider as upgraded replacements?
I just found myself in the exact same situation. I wonder if I would improve the bottom end of the overall presentation going from a 85W amplifier (4 ohms) to 150W
