Why are the vocals on some records hidden behind the music on my system?


Help! I am new to this forum, but have been into audio for over 45 years and have never had this problem before. I was lucky enough to come into some money and decided to use some of it to up grade my system for the first time in almost 30 yrs. The system consists of McIntosh MC-402, McIntosh C-100, McIntosh MCD-500, VPI HW19 MKIII, Soundsmith Aida, Furutech Ag-12 phono cable, Furutech silver head shell wires, Furutech interconnects and Furutech speaker cables (yes I like Furutech) and Raidho XT-3 speakers. Now on some albums the vocals are buried behind the music and you have a really hard time hearing the singer? Not all albums are voiced in this manner but enough that it is bothersome. I have a large dedicated man room (24 x 27) with minimum treatment. CDs sound just fine so I feel that it is with the phono preamp in the C-100? I have moved the speakers 100s of times and have them at 5' 8" apart and 8' 1" to the focal point and the soundstage is good and the vocals are better, but you still have to really listen hard to hear certain vocals on some albums. Most of my albums are 30 to 50 years old and have been cleaned with a sonic cleaner (best thing ever imho). Even some of my new heavy vinyl has this problem.

cleeds - the alignment itself didn't take 2 1/2 hrs but making adjustments to the vta is a change an listen to see if it is better or worse then doing that over an over until you find what you feel is the best . almarg - maybe I don't have the PT-6 it might be a PT-5 because there is no dial to adjust vta only a set screw to tighten after manually raising or lower the tone arm by feel, I wish there was a calibrated dial it would have been so much easier.  I though it was the PT-6 because of some other differences in the vinylengine.com library to the PT-5. The overhang is 18mm as it is for a 9" tone arm which is what the ProJect shows it to be also. The mirror on the Pro-Ject is for adjusting azimuth. Your method of setting anti-skate sounds similar to what I stated except you use cantilever deflection instead to tonearm drift. Your way may be more accurate so it's something I can try.

Note though that my post referred to the dial for setting VTF (i.e., tracking force), not VTA.

It sounds like you're relying on intuition and feeling here. While I think listening is a critical part of phono cartridge setup, you're chasing your tail if you don't start with measurements, imo. For VTA, that means using a VTA alignment gauge. For overhang and tangency it means using a mirrored alignment gauge that aligns the actual cantilever, rather than the cartridge body. There are so many variables in phono cartridge setup that if you rely on crude tools and listening alone, achieving proper alignment is very much a hit-or-miss proposition. And while it's difficult to diagnose a problem such as yours remotely, it sure sounds like a setup problem to me.

Your speakers too can  clash with your amp,preamp 
the McIntosh are decent but a Pass Labs 250.8 would destroy it 
as well as Ampzilla ,and ambrosia Amp,preamp  little kniwn gems 
from late great Jim Borgiano. Nelson Pass New 250.8 
and many others are far more refined.
i sold Macintosh  nice Looking and dependable, but not the last word in resolution.  For Cd McIntosh for not their Forte.
look up the Lascala, Tube dac, or a Great Lampizator dac ,
or manygreat players .  Rule of thumb don’t buy everything  from 
one company  ,no one makes great everything 
 unless you have $$. Gryphon  .comes to mind , Goldman,
 great Swiss company not too expensive Ensemble.
  Even cables are system dependent . Your system is good 
just a few things  can be bettered for similar  money’s that we’re spent.  Just speaking the truth .having owned a store .

audioman- being in a HI-FI deprived area (rural Okla.) I would have to gone to Dallas, Houston, Denver you get the picture, just to check out any HI-FI stores (unless you count BestBuy). So I bought something that I had heard in the past that sounded good. Now I did go to RMAF in 2017 to hear the Raidho speakers (XT-2 and D-1.2). Wish it was like the 70's with a audio store on every other corner (I lived in Tulsa most of my life). Maybe one of these days I can change it up a bit? Plus all these are used so I didn't pay full price even though it still was a lot of money for me.
