Had the opportunity to demo a Grado Opus3, and have some interesting findings!
In a nutshell, coming from series 2 Prestige experience, it's true that the Opus3 just has more of all the great qualities of a Prestige. It's just better, period. The low end is round, rich, and intoxicating, and the top end is even more clear and detailed than an 8MZ. It tracks inner grooves much more accurately, with less distortion throughout the side. It's extremely musical - sometimes I got lost in it, other times I audibly "wow!"'d. Some of its most impressive qualities are in the soundstage. It is remarkably wide, stereo separation is 3D and lifelike in a way that I haven't experienced before.
However, of that same wide soundstage is where I encountered an issue, at least in my setup. I initially thought that my right channel was coming in a smidge quieter than my left. I rebalanced without improvement, then checked Azimuth, which perhaps was just a tick off. It was tricky to see with my ruler, but I put the possibility in play. Unfortunately on the VPI Cliffwood, Azimuth isn't adjustable, but the Opus did come with a couple of nuts/spacers that I didn't initially use, and one of those seemed to satisfy my eye that any tilt was corrected. Initially I did notice a bit more juice out of the right channel as was corrected for, but something still wasn't quite right.
Then it clicked for me that vinyl is cut lat/vert, or mid/side, meaning there is information in the center of the image, and information on the left and right sides. What I experienced was that the lateral audio was unbalanced - the hard panned stuff on the left was coming in stronger, with more presence and top end than the right channel side audio. For example, if there was a cut with hard panned guitars, the left channel guitar would be much cleaner, more present, and therefore appear louder than the right side, which in comparison felt muffled and less dynamic.
To make sure I wasn't going crazy and to rule out any issue with the turntable, I switched back to the Goldring E3 I'd had on previously, and sure enough, a balanced picture emerged from the hard panned audio, albeit not with quite the vividness of the Opus3, but vastly more balanced. And a silver lining here, I was never really wowed with the Goldring, but after re-mounting, it clicked for me. It now sounds lively and exciting to my ear, without being overly bright. It's a rocker! Funny how fickle of a format this is!
Anyway, apologies for the essay, but hopefully some of this was useful? To finish with a question for all - has anyone experienced this issue before? My only thought is that perhaps since the VPI has no anti-skate, that the Opus3 would perform better with it - maybe it was riding the inner wall of the groove harder, which would be the right channel, and that had some effect on the dynamics? I enjoyed the Opus so much that I might just be crazy enough to give it a roll on another deck! Haha.
Massive thank you in order to
@AnthonyI for making all of this possible. Spin on everybody!
