Currently use the Vincent phono preamp 8.

Any suggestions for stepping up without spending more than $1000?  
This tough because the PHO 8 is spectacular for the money.  I used one for several years.  I am not going to mention the phono stage that I purchased for just under $1000 on sale which was not an upgrade and is literally the most disappointing unit I have ever purchased.  

You best bet is probably the Musical Surrounding Phonomena II+ which I think is $750 new.  Great unit.

The Musical Fidelity MX VINYL was discontinued.  I could try and get you one as it looks like their is still inventory at the wholesaler.  It is $999.  

Those are your two best options IMO.  
Thanks for the info, I will look at both.
