Vinyl Newbie - So Many Questions!


New to these forums and new to vinyl, but longtime audiophile, so I feel comfortable saying that I know what I’m hearing but can’t figure out why. 

It would probably help if I summarize my system to aid in troubleshooting:

Marantz TT 15S1

iFi Zen phono preamp

Naim Uniti Atom as streamer/preamp/dac

Conrad Johnson CAV-45 S2

Klipsch Cornwall IV

I’ll start with the easy one

1.  I followed the setup instructions for the Marantz tt meticulously. Every time I start the motor, the belt squeaks and slips on the motor pulley before getting up to speed. It’s annoying and really cheapens the experience. Is this normal?

 

2.  The sound quality ranges from very bad to very good, largely dependent on the record. I don’t have a large collection as I just started with vinyl, but many of these pressings sound absolutely terrible. Many sound distorted and compressed. Many have tons of clicks and pops. I double checked the settings on my phono preamp which is really just moving magnet. There aren’t a lot of settings. One for MM and three for MC. I connected the phono preamp directly to the Conrad Johnson instead of the analog input on the Naim and while it does sound “better”, it’s mostly the same. 
 

I don’t have another cartridge or phono preamp to swap out and try to isolate the issue. Could it simply be that the phono preamp is defective?  It seems that if the cartridge was defective it would just all sound bad.  Could it be that my system is revealing enough that it’s showing the limitation of the iFI?  I just think it would sound “good” all the time, but never really “great”. Could it be that all of these pressings are so incredibly crappy that I’m hearing just how bad they are?

The couple of “mainstream” records do sound pretty good. Namely Gregory Porter, Adele, Gary Clark Jr, Miles Davis, John Coltrane. But even a couple of those have inconsistently cut holes for the spindle (some of them bind), significant warps, and some off-center labels. The independent stuff is all over the map. A couple of the John Prine pressings sound very good, but have soooo many clicks and pops it’s ridiculous - even after cleaning. And one of them wouldn’t even go on the spindle because the hole was so small. 
 

Anyway, I’m just perplexed and pretty annoyed. I’ve debated buying another turntable (with cartridge) and phono preamp just to see if there’s any change.  Any suggestions?  Is that my best course of action - to just buy another preamp and cartridge to troubleshoot?

Thanks again everyone. A couple of clarifications:

 

I am currently running the phono preamp directly into the CJ which, as someone else stated, is a control amplifier (integrated amp minus any gain stage).  It’s basically an MV-60 with three inputs and a volume control. 
 

I also remove the dust cover for all listening.

 

The cartridge is a Clearaudio Virtuoso - a MM cart that sells for around $1,000. 
 

The iFi does not allow for adjustment to the MM cartridge load and is defaulted to 47k ohms. 
 

I do not have a stylus pressure gauge but followed the setup instructions very carefully and believe it is set at the recommended pressure - certainly within the recommended range. 

Phono cables?

input capacitance at the iFi MM inputs? (Input stage also adds capacitance. We need to figure out the total capacitance seen by your cartridge.)

Sounds like you have some very decent equipment and things just need tweaking. You've got some great advice here so I'm sure things will fall into place. An ultrasonic cleaner is not a necessity but clean records are and there is plenty of advice using various methods to be found. I am a fan of solutions with no alcohol and have had great success with Disk Doctor and recently a fantastic lens cleaning solution called Bi-Oh! Disk Doctor solution is no longer available :(

As for cleaning/treating rubber belts stay away from alcohol since it dries out rubber. Use Rubber Renue by MG Chemicals.

Recommended load capacitance for your Virtuoso is 100 pF. MM input C for the Zen is 110pF. So even before adding C due to your phono cables, you are at the outer edge of the C your cartridge “likes”. Cables can easily add another 100pF even if short in length. What cables and what length?

Yes... a phono preamp is meant to plug into a preamp... it should be OK.

If your preamp sounds ’right’ with CD, etc. ... it should work with ifi

Go to Clear audio to get specs for your cartridge... 47k ohms should be OK.

GET A FORCE GUAGE.... they are cheap. You cannot properly set up your TT and cartridge without one.

Once you have made sure your cartridge is setup... you can play with VTA (height of tonearm) start at dead level, raise or lower to your preference.

Make sure your records are clean. Get on u-tube and watch setup videos and cleaning videos... helps newbies.

If your cartridge has collapsed... clear audio has a trade in , trade up program.

BUT... more than likely it’s your setup skills... no offense... try again with the proper tools.

AND... the belt. Take it off, put in a bag with a little baby powder... shake it. May help. Belts stretch..they are a wear item... you can replace it.
