advice for warming up phono sound


I currently have a Rega P3 with a Nagaoka mp200 running to a schitt mani phono pre and a Peachtree nova 300 and Paradigm prestige 75 speakers.  I'm finding the sound to be a bit harsh.  Saxophones lack a little body and reverb is very pronounced and a bit glassy.  I'm thinking of replacing the phono pre.  I've heard great things about the Avid Pellar but I'm wondering, if I want to warm up the sound to something more natural, should I be thinking tubes?  I'm also wondering if anybody has any thoughts about replacing the glass platter with delrin as way to warm things up.  Thanks!

Get a cork mat and recheck the alignment of the cartridge - particularly the SRA. Also check the tracking force. Give the stylus a good cleaning with a Magic Eraser (use it after every side!). Don't forget that LPs vary widely in SQ!
Almost forgot: get and use a record weight to get a better coupling of the record to the mat!
the harshness is likely coming from your phono pre.
if you are a DIYer you can replace those red wima caps with Nichicon XY series, much better sounding cap.

If not a DIYer, then would suggest looking for a diff phono pre.
