Pro-Ject Extension 12 to SME Model 10


Hello,
I am considering upgrading my turntable from a Pro-Ject Extension 12 to a SME Model 10.
Would this be a worth while upgrade?
Would it actually sound better?
Is there another turntable in the price range of the SME Model 10 to consider?
I am unfamiliar with the benefits of upgrading the turntable as this is the first that I have owned.
I would keep my current cartridge a Sumiko Pearwood Celebration II.
Any advice would be appreciated.
Thank You

Thank you for the responses.

The Pro-Ject Extension 12 is the companies first venture into making a higher end product which lists for $5000 and punches above its weight so to speak. It includes a 12" carbon fiber arm and it is sturdy as it weighs over 50 lbs.

I have been told that my turntable is the weak link in my system. My system consist of a Conrad Johnson ARTsa amplifier, Conrad Johnson ET7s2 for a Preamp, Audio Research Ref 2 se Phono Pre and Nola Grand Metro Reference Gold Speakers.

I find vinyl to have a much fuller sound with better low end grunt, separation of instruments, more detail, black space between instruments, better clarity in vocals and simply more pleasing to my ears.

Any suggestions on a turntable that would be an upgrade giving me more of the positive attributes that vinyl delivers?

The turn table does not have to be a SME. I would buy a used turntable as I can get better value.

Thank you for the advice.

Pkelly1504, it will be very interesting to know why you plan upgrade have you found negative SQ in Xtension 12?

I have P-J RPM 9.1 and thinking my next upgrade: Xtension 12 or Signature 10.

The best recommendation I received are: Brinkmann (Brado, Osis), Clearaudio (Innovation, Ovation), VPI (Prime 21 and Signature).  But these cost a lot new, and need expensive dust cover.

Based on price point and top level X-line, Xt12 seems very high end, being weakest link in your system might be not valid I will investigate this if I ware you. It is possible need spend a lot money to get better sound from you already have..., not wise!

Also consider upgrading power plug from wall wart to box use detachable power cord, in case you haven't done that.

Also look for upgrading tonearm to better model (Breuer, Graham, Jelco are good example), tonearm can make significant improvement.

Good luck
@knight7m , You should upgrade your list with the Sota Nova Vacuum. It can also be had with a beautiful dust cover!
Agreed mijostyn5.
I like know what SQ differences between Sota and VPI.   I dont like tube sound, its moody and put me into sleep.   I like SS sound but similar to Krell: definations, resolution, extensions, neutral.
