Warm sounding phono cartridge

Clicks and pops after ultrasonic cleaning either suggest really poor quality or damaged vinyl records, or something is off with your cleaning procedure.

Re thin sound, consider experimenting with loading setting on your phono stage. I don't know recommended loadings for your two carts and what your PS has as options. I also found that putting a SUT between MC cart and MM-in of PS generates a fuller sound.

Also adjusting tracking force may change the sound quite a bit. VTA for some has a strong effect; I could not hear anything.

I have 2 phono stages.  A Manley Chinook and a Hegel V10.  I have played with the loading on both and get similar results. Although the Hegel seems to have less top and bottom to me than the Manley.  A good example is I just bought a Jackson Browne Somebody's Baby 12' Single Promo Released in 1982.  The condition is very good.  The album is quiet but sounds thin to me using the Hana.  A lot of the albums that I own of that vintage seem to have a similar sound to them.  Is there a cartridge that can add some color and fullness?  Something that is easy to listen to that doesn't necessarily add a lot of detail.

@artemus_5 It could possibly be due to the cartridge change.

When I upgraded from a Dynavector XV-1s to a Lyra Atlas I was amazed at how much less I noticed ticks and pops on my old records. As if they had disappeared. Someone I know at Audio Quest who used to handle the Lyra line explained it this way,

I think what you are hearing re ticks is the fact that the Lyra has a much faster transient response, which also means it has less overhang. Tics and pops start and stop very quickly and have less audible impact on what you hear.

It may just come down to differences in the cartridges. A less resolving cartridge may or may not be the answer

I have a Hana ML cartridge and I don't have an issue with popping or thin sound. I use a Sutherland TZ Vibe photo stage.  I just listened to it last night and it sounds great. 

Maybe try an elliptical?

I had a Dynavector Karat with an elliptical that was 'fat' or full sounding.

If a phono stage doesn't have 'headroom' sometimes the pops and clicks don't attenuate well.  I agree with the other poster: if after cleaning you still get them, it's the vinyl.

Maybe try rolling some 6922s in the Manley to get the sound you like?  Tons of 6922/6DJ8 to try out there.
