Clearaudo Concept vs Rega P6

You may be able to find some prior posts on this forum discussing the Concept TT vs different Rega TT's that might be helpful but probably not down to the carts that you are considering. 
 

I recently compared the P6/330/Ania to the Mofi Ultradeck with MoFi's better cartridge and the Clearaudio Concept with the Clearaudio MM cartridge (the $250 one).

I kept the Rega.  In my system, at least, it was noticeably better - quieter, less colored, more explosive and propulsive - than the others.  Part of that was due to the Ania MC cartridge digging out more detail, but having heard the Rega with the Exact2 MM cartridge, most of the difference is from the table/arm.  It's a great combination, and I wouldn't be surprised if it wouldn't be better than my old LP12/Lingo/Cirkus/Aro/Troika setup from long ago.  

That said, system matching matters - I have an Exposure 3010S2 preamp and 3010S2 monoblocks driving Monitor Audio GX300 speakers, and it's not hard to imagine a system where the Clearaudio or MoFi tables worked more synergistically, even if the Rega's margin over those two was significant.  IMO, obviously.  

I would go with the Clearaudio.  I had a Rega Planar 3 and hated it. Much too lightweight sound.  

Clearaudio Concept.

I had the Rega and then switched over to the Clearaudio Concept. Its much more robust.

 Went to Concept Wood from Rega P25, nice step up

@cafb71 Have you considered the -  Music Hall MMF-7.3 2 Speed Belt Drive Turntable - it's about the same price as the Rega.

Features: 

• music hall’s unique dual-plinth construction
• one-piece full carbon fiber tonearm
• fully adjustable VTA, azimuth, and dampened arm lift mechanism
• counterweight’s center of gravity is level with the stylus tip, is decoupled from the arm, and acts as a resonance damper
• completely isolated/decoupled DC motor with 33 and 45 rpm speed controls located in the front left corner of the turntable, thus canceling any potential vibration from the motor/belt to the cartridge
• motor sits on its own resonance-damping puck
• precision stainless steel main bearing sheathed in Teflon® for noise-free, fluid operation
  
• non-resonant acrylic platter with metal screw-on record clamp and soft felt mat
• high-quality gold RCA connectors and detachable phono cable
• adjustable tip-toe feet with anti scratch cups
• low-noise, fully-manual belt drive design
• built-in round spirit level for proper leveling

I'm  not sure if the arm is a good match to your existing cartridge

Just something else to consider - Steve

Well, I went with the Rega Planar 6 with NEO PSU, fitted with the Rega Ania Pro MC and also upgraded to the Eat E-Glo Petit Tube Phonostage.  Should have it all within 4 weeks or so.  Thanks for all those who weighed in.

Great choice.

I agree, excellent choices.

Enjoy!

A great table/arm/cartridge combination.
