First Preamp with Proper Balance

Greetings,
I am wondering if anyone else has had the experience I have; after several receivers, pre/amp combos etc. I just recently put a Rogue Audio Magnum 66 into my system. It is the only time I have ever heard the system sound truly balanced!
All these years I have sensed that the right channel is slightly stronger than the left. This was true with receivers years ago and in this system preamps such as a Meridian 501 and Audio Research LS-9, both good pieces of equipment.

I have changed nothing else, just the preamps. But the Rogue gets the separation and STRENGTH of each channel perfect! I always thought I'd just have to live with that anomaly - the slightly stronger right channel. The Meridian had balance control, and I ususally had to pump up the left channel quite a bit (no, room anomalies were not the cause). The Audio Research had no balance control. But when the Rogue was inserted into the system, the "rightness" of it was clear, almost shocking!

This is almost a scary discovery, that a higher end piece of equipment such as Meridian or Audio Research might "skew" the balance/separation so much!

Again, no, there are no other issues such as a bad amp channel, mismatched interconnects, polarity messed up, etc. Plain and simple, these other amps sounded too right - pardon the pun - too much right channel and not enough left. And, lest I receive a barrage of hearing loss jokes, I believe my hearing is just fine. Of course, maybe deaf people just think everyone else speaks too softly! ha

Has anyone else ever had similar experience. I'm inclined to believe that the Rogue has superior design, at least in that regard. When I first heard the Rogue in my system, this correction of left/right channel was so astounding, I sat for hours listening, thinking THIS is how it's SUPPOSED to sound!!!!
