I recently pulled out my old Technics SL-1350 direct-drive turntable and connected it to a Pyle PP444 preamp and Marantz SR-5010 receiver, both new. I listened to a dozen of my LPs from the '60s and '70s. TT ran fine, but something was obviously wrong. In all the vocals, the lead singers sounded faint and hollow; like they were recorded in a deep well, while the backup singers and instruments were quite prominent. I dragged out my Behringer UFO202 and 40-year-old Olson preamps - same problem with both. My cartridge is a Shure M55E. Do cartridges go bad? What else could be wrong? I'm stumped!

Somewhere in the wiring, you reverted to karaoki mode. Singers are almost always center channel.

Inverting the ground and hot for one channel of the two will cancel the center channel.

Harry may have the answer. Speaker phasing is very important. If you have the same problem using headphones, then it is not speaker phasing.

Other things to consider are whether you are plugged into an input with RIAA equalization - usually an input labelled phone (for phonograph, but read the pre-amp instructions)

Bad stylus might be a problem, but I don't know what it would sound like. If you have a magnifying glass, you might want to look at the stylus tip. They can get chipped and get crudded up, with bad consequences.

Thanks to all of you for your comments. The mystery is solved! The comments I received started me re-thinking the problem. Harry's words, "singers are almost always center channel" particularly set me on the right path. I had been eyeing the center channel speaker output on my new Marantz. Not using it; just looking at it and thinking about it, repeatedly. You see, the last time my turntable played, it was hooked up to a stereo Altec receiver, decades ago; ya' know, back in the 2.0 days. The records all sounded great in 2.0, but we hadn't been spoiled by surround sound yet, at least not in our homes.
Now comes my mighty 7.1 channel Marantz, and the lead singers are all but lost... why?... because it was just a temporary 2.0 channel hookup, to check the new receiver and the old turntable.
Then today bigbear posted, "If you have the same problem using headphones, then it is not speaker phasing." So I plugged in the headphones and I did NOT have the same problem. I instantly realized the center channel was not optional! I dashed to my storeroom and dug out a 1962 University bookshelf speaker to use as a temporary center channel. Voila! The "Frankie Valli sound" was back! (And all the other leads, too.) I just ordered a JBL Loft 20 for my new center channel speaker, and I had already been replacing several bad electrolytic capacitors in my JBL E250P powered subwoofer. Along with my two venerable JBL J325A mains, it should all shape up into a decent 3.1 channel phono system.
Thanks again!

That's a good question to ask. They are all originals.

Dude111, are you sure you know what you're talking about? There are NO digital LPs. LPs are strictly analog. Yes, some LPs have been "digitally" remastered and reissued, but the digital remastering is an intermediate step - the content goes from old master audio tape (analog), converted to digital, digitally edited, and then output as an analog signal for cutting the master disc.

Why a digital intermediate? Because digital allows things like noise reduction and mixing more easily than the old analog equipment so you end up with an analog signal that's lower in noise, better fidelity, better equalization and such.
